Axis of Xamarin.Android Chart (SfChart)

25 Nov 202224 minutes to read

Charts typically have two axes that are used to measure and categorize data: a vertical (Y) axis, and a horizontal (X) axis.

Vertical(Y) axis always uses numerical scale. Horizontal(X) axis supports the following types of scale:

• Category
• Numeric
• Date time

The following APIs are available in ChartAxis:

• VisibleLabels - Represents the axis label collection, which is visible in axis.
• VisibleRange - Represents the Start and End range of an axis. The Delta property of VisibleRange represents the delta value.

Category Axis

Category axis displays text labels instead of numbers.

C#

[C#]

chart.PrimaryAxis = new CategoryAxis();

Placing labels between ticks

Labels in category axis can be placed between the ticks by using LabelPlacement property of categoryAxis. Default value of LabelPlacement is OnTicks i.e. labels will be placed on the ticks by default.

C#

[C#]

chart.PrimaryAxis = new CategoryAxis() 
{ 
	LabelPlacement = LabelPlacement.BetweenTicks 
};

Displaying labels after a fixed interval

To display labels after a fixed interval n, you can use Interval property of ChartAxis. Default value of interval is 1 i.e. all the labels will be displayed by default.

C#

[C#]

chart.PrimaryAxis = new CategoryAxis() 
{ 
	Interval = 2, 
	LabelPlacement = LabelPlacement.BetweenTicks 
};

Indexed category axis

Category axis can also be rendered based on the index values of data source by setting the ArrangeByIndex property to true in the axis.

C#

[C#]

chart.PrimaryAxis = new CategoryAxis() 
{ 
	ArrangeByIndex = false 
};

ColumnSeries series1 = new ColumnSeries()
 {
        ItemsSource = view.Data1,
        XBindingPath = "Country",
        YBindingPath = "Year2016"
 };
 ColumnSeries series2 = new ColumnSeries()
 {
        ItemsSource = view.Data2,
        XBindingPath = "Country",
        YBindingPath = "Year2016",
 };

chart.Series.Add(series1);
chart.Series.Add(series2);

Numeric Axis

Numeric axis uses numerical scale and displays numbers as labels.

C#

[C#]

chart.PrimaryAxis = new NumericalAxis();

Customizing numeric range

To customize the range of an axis, you can use the Minimum and Maximum properties of NumericalAxis. By default, nice range will be calculated automatically based on the provided data.

C#

[C#]

chart.SecondaryAxis = new NumericalAxis() 
{ 
	Minimum = 10, 
	Maximum = 50
};

Customizing numeric interval

Axis interval can be customized using the Interval property of ChartAxis. By default, nice interval will be calculated based on the minimum and maximum value of the provided data.

C#

[C#]

chart.SecondaryAxis = new NumericalAxis() 
{ 
	Interval = 10 
};

Apply padding to the range

Padding can be applied to the minimum and maximum extremes of the axis range by using RangePadding property. Numeric axis supports the following types of padding.

• None
• Round
• Additional
• Normal
• RoundStart
• RoundEnd
• PrependInterval
• AppendInterval

None

When the value of RangePadding is None, padding will not be applied to the axis. This is also the default value of RangePadding for horizontal axis.

C#

[C#]

chart.SecondaryAxis = new NumericalAxis() 
{ 
	RangePadding = NumericalPadding.None 
};

Round

When the value of RangePadding is Round, axis range will be rounded to the nearest possible value by the interval.

C#

[C#]

chart.SecondaryAxis = new NumericalAxis() 
{ 
	RangePadding = NumericalPadding.Round 
};

Additional

When the value of RangePadding is Additional, axis range will be rounded and an interval of the axis will be added as padding to the minimum and maximum values of the range.

C#

[C#]

chart.SecondaryAxis = new NumericalAxis() 
{ 
	RangePadding = NumericalPadding.Additional 
};

Normal

When the value of RangePadding is Normal, nice range will be calculated for the axis based on the best readability of the data. This is also the default for vertical axis.

C#

[C#]

chart.SecondaryAxis = new NumericalAxis() 
{ 
	RangePadding = NumericalPadding.Normal 
};

RoundStart

When the value of RangePadding is RoundStart, axis range will be rounded in the start to the nearest possible value by the interval.

C#

[C#]

chart.SecondaryAxis = new NumericalAxis() 
{ 
	RangePadding = NumericalPadding.RoundStart  
};

RoundEnd

When the value of RangePadding is RoundEnd, axis range will be rounded in the end to the nearest possible value by the interval.

C#

[C#]

chart.SecondaryAxis = new NumericalAxis() 
{ 
	RangePadding = NumericalPadding.RoundEnd  
};

PrependInterval

When the value of RangePadding is PrependInterval, axis range will be rounded and an interval of the axis will be added in the start as padding to the minimum values of the range.

C#

[C#]

chart.SecondaryAxis = new NumericalAxis() 
{ 
	RangePadding = NumericalPadding.PrependInterval 
};

AppendInterval

When the value of RangePadding is AppendInterval, axis range will be rounded and an interval of the axis will be added in the end as padding to the maximum values of the range.

C#

[C#]

chart.SecondaryAxis = new NumericalAxis() 
{ 
	RangePadding = NumericalPadding.AppendInterval 
};

Auto Interval On Zooming

AutoIntervalOnZoomingEnabledproperty determines the update of axis interval based on the current visible range while zooming the chart. Default value of this property is true. If this property is false, the nice interval will not be calculated for new range after zoom in and actual Interval will be sustained.

C#

[C#]

NumericalAxis primaryAxis = new NumericalAxis()
{
    AutoIntervalOnZoomingEnabled = true
};

Date Time Axis

Date time axis uses date time scale and displays date time values as axis labels in specified format.

C#

[C#]

chart.PrimaryAxis = new DateTimeAxis();

Customizing date time range

To customize the range of an axis, you can use the Minimum and Maximum properties of DateTimeAxis. By default, nice range will be calculated automatically based on the provided data.

C#

[C#]

Calendar calendar = new GregorianCalendar(2010, 1,1);
DateTimeAxis dateTimeAxis = new DateTimeAxis();
dateTimeAxis.Minimum = calendar.Time;
calendar.Set(2015, 12,30);
dateTimeAxis.Maximum = calendar.Time;
chart.PrimaryAxis = dateTimeAxis;

Date time intervals

Date time intervals can be customized using Interval and IntervalType properties of the DateTimeAxis. For example, setting Interval as 2 and IntervalType as Years will consider 2 years as interval.

Essential Chart supports the following types of interval for date time axis

• Years
• Months
• Days
• Hours
• Minutes
• Seconds
• Milliseconds

C#

[C#]

chart.PrimaryAxis = new DateTimeAxis() 
{ 
	IntervalType = DateTimeIntervalType.Months, 
	Interval = 6
};

Apply padding to the range

Padding can be applied to the minimum and maximum extremes of the range by using RangePadding property. Date time axis supports the following types of padding:

• None
• Round
• Additional
• RoundStart
• RoundEnd
• PrependInterval
• AppendInterval

None

When the value of RangePadding is None, padding will not be applied to the axis. This is also the default value of RangePadding.

C#

[C#]

chart.PrimaryAxis = new DateTimeAxis() 
{ 
	RangePadding = DateTimeRangePadding.None 
};

Round

When the value of RangePadding is round, axis range will be rounded to the nearest possible date time value.

C#

[C#]

chart.PrimaryAxis = new DateTimeAxis() 
{ 
	RangePadding = DateTimeRangePadding.Round 
};

Additional

When the value of RangePadding is Additional, range will be rounded and date time interval of the axis will be added as padding to the minimum and maximum extremes of the range.

C#

[C#]

chart.PrimaryAxis = new DateTimeAxis() 
{ 
	RangePadding = DateTimeRangePadding.Additional 
};

RoundStart

When the value of RangePadding is RoundStart, axis range will be rounded in the start to the nearest possible date time value.

C#

[C#]

chart.PrimaryAxis = new DateTimeAxis() 
{ 
	RangePadding = DateTimeRangePadding.RoundStart 
};

RoundEnd

When the value of RangePadding is RoundEnd, axis range will be rounded in the end to the nearest possible date time value.

[C#]

chart.PrimaryAxis = new DateTimeAxis() 
{ 
	RangePadding = DateTimeRangePadding.RoundEnd 
};

PrependInterval

When the value of RangePadding is PrependInterval, range will be rounded and date time interval of the axis will be added in the start as padding to the minimum extremes of the range.

C#

[C#]

chart.PrimaryAxis = new DateTimeAxis() 
{ 
	RangePadding = DateTimeRangePadding.PrependInterval 
};

AppendInterval

When the value of RangePadding is AppendInterval, range will be rounded and date time interval of the axis will be added in the end as padding to the maximum extremes of the range.

C#

[C#]

chart.PrimaryAxis = new DateTimeAxis() 
{ 
	RangePadding = DateTimeRangePadding.AppendInterval 
};

Date-time category axis

The DateTimeCategoryAxis is a unique type of axis used mainly with financial series. Like CategoryAxis, all the data points are plotted with equal spaces by removing space for missing dates. Intervals and ranges for the axis are calculated similar to DateTimeAxis. There will be no visual gaps between points even when the difference between two points is more than a year. The following APIs are used to customize the interval of DateTimeCategoryAxis.

• Interval - Gets or sets the double value that represents the interval between the labels.
• IntervalType - Gets or sets the DateTimeIntervalType that represents the type of the interval to be displayed.

C#

[C#]

DateTimeCategoryAxis xAxis = new DateTimeCategoryAxis();
xAxis.Interval = 1;
xAxis.IntervalType = DateTimeIntervalType.Months;
chart.PrimaryAxis = xAxis;

Logarithmic Axis

Logarithmic axis uses logarithmic scale and displays numbers as axis labels.

C#

[C#]

chart.SecondaryAxis = new LogarithmicAxis();

Customizing the logarithmic range

To customize the range of log axis, you can use the Minimum and Maximum properties of LogarithmicAxis. By default, nice range will be calculated automatically based on the provided data.

C#

[C#]

chart.SecondaryAxis = new LogarithmicAxis()
{
    Minimum = 100,
    Maximum = 10000
};

Logarithmic Base

To change the log base value, you can use LogarithmicBase property.

C#

[C#]

chart.SecondaryAxis = new LogarithmicAxis()
{
    LogarithmicBase = 2
};

Common Axis Features

Customization of features such as axis title, labels, grid lines and tick lines are common to all the axes. Each of these features are explained in this section.

Axis Visibility

Axis visibility can be controlled using the Visibility property of axis. Default value of Visibility is Visible.

C#

[C#]

chart.SecondaryAxis.Visibility = Visibility.Gone;

C#

[C#]

chart.PrimaryAxis.LabelStyle.TextColor = Color.Red;
chart.PrimaryAxis.LabelStyle.TextSize = 12;
chart.PrimaryAxis.LabelStyle.Typeface = Typeface.DefaultBold;

Format the Labels

Axis labels can be formatted using LabelFormat property of ChartAxis. This supports all the SimpleDateFormat patterns for date time axis and all the DecimalFormat patterns for the number axis.

Label and Tick Positioning

Axis labels and ticks can be positioned Inside or outside the chart area by using LabelStyle.LabelsPosition and TickPosition properties of ChartAxis. By default labels and ticks will be positioned outside the chart area.

C#

[C#]

chart.PrimaryAxis.LabelStyle.LabelsPosition = AxisElementPosition.Inside;
chart.PrimaryAxis.TickPosition = AxisElementPosition.Inside;

Axis Label Rotation

The axis label can be rotated by using LabelRotationAngle.

C#

[C#]

chart.PrimaryAxis.LabelRotationAngle = 315;

Edge Labels Placement

Labels with long text at the edges of an axis may appear partially outside the chart. The EdgeLabelsDrawingMode property can be used to avoid the partial appearance of labels at the corners. Default mode is Center.

C#

[C#]

chart.PrimaryAxis.EdgeLabelsDrawingMode = EdgeLabelsDrawingMode.Shift;

Edge labels visibility

The visibility of the edge labels in an axis can be controlled using EdgeLabelsVisibilityMode property.

The following options are available in EdgeLabelsVisibilityMode,

• Default - used to display the edge label based on auto interval calculations
• Visible - used to display the edge labels (first and last label) irrespective of the auto interval calculation until zooming (i.e., in normal state).
• AlwaysVisible - used to always display the edge labels even while zooming the chart.

The following code example demonstrates the AlwaysVisible option while zooming.

C#

[C#]

chart.PrimaryAxis = new NumericalAxis()
{
    EdgeLabelsVisibilityMode = EdgeLabelsVisibilityMode.AlwaysVisible
};

Axis line offset

AxisLineOffset property can be used to set offset value for the axis line.

C#

[C#]

chart.PrimaryAxis = new NumericalAxis()
{
    AxisLineOffset = 15,
};

Label extent

The LabelExtent property allows to set the gap between axis labels and title. This is typically used to maintain the fixed gap between axis labels and title when the digits of the axis value changed in live update.

C#

[C#]

chart.PrimaryAxis = new CategoryAxis()
{
    LabelExtent = 50
};

Offset the rendering

The PlotOffset property is used to offset the rendering of the axis at start and end position. The following code snippet demonstrates to apply the plot offset to both x and y axes.

chart.PrimaryAxis.LineStyle.PathEffect = new DashPathEffect(new float[] { 4, 4 }, 3);

Grid Lines Customization

The ShowMajorGridLines and ShowMinorGridLines properties are used to control the visibility of grid lines. MajorGridLineStyle and MinorGridLineStyle properties in axis are used to customize the major grid lines and minor grid lines of an axis respectively. By default minor grid lines will not be visible.

The grid lines can be customized using following properties:

• StrokeColor - used to change the stroke color of the grid lines
• StrokeWidth - used to change the stroke width of the grid lines

chart.SecondaryAxis.MinorTicksPerInterval = 2;

Tick Lines Customization

The MajorTickStyle and MinorTickStyle properties in axis are used to customize the major tick lines of an axis and minor tick lines of an axis respectively. They provide options to change the StrokeWidth, Size, StrokeColor and Visibility of tick lines. By default minor tick lines will not be visible. MinorTicksPerInterval property can be used to specify the number of minor ticks per interval that resided between the adjacent major ticks.

C#

[C#]

NumericalAxis numericalAxis = new NumericalAxis();
numericalAxis.MajorTickStyle.TickSize = 7;

ChartAxisRangeStyleCollection axisRangeStyles = new ChartAxisRangeStyleCollection();

ChartAxisRangeStyle rangeStyle = new ChartAxisRangeStyle() { Start = 15, End = 21};

rangeStyle.MajorGridLineStyle = new ChartLineStyle() { StrokeColor = Color.ParseColor("#096EBF"), StrokeWidth = 3 };

rangeStyle.LabelStyle = new ChartAxisLabelStyle() { TextColor = Color.ParseColor("#096EBF"), Typeface = Typeface.DefaultBold }; 

axisRangeStyles.Add(rangeStyle);

....

numericalAxis.RangeStyles = axisRangeStyles;

Inversing Axis

Axis can be inversed using the Inversed property of axis. Default value is False.

C#

[C#]

chart.SecondaryAxis.Inversed = true;

Placing Axes at the Opposite side

The OpposedPosition property of axis can be used to place the axis at the opposite side of its default position. Default value is False.

C#

[C#]

chart.SecondaryAxis.OpposedPosition = true;

Maximum number of labels per 100 pixels

By default, a maximum of 3 labels are displayed for each 100 pixels in axis. The maximum number of labels that should be present within 100 pixels length can be customized using the MaximumLabels property of an axis. This property is applicable only for automatic range calculation and will not work if you set value for Interval property of an axis.

C#

[C#]

chart.SecondaryAxis.MaximumLabels = 5;

AutoScrollingDelta

AutoScrollingDelta is used to ensure that the specified range of data is always visible in the chart. It always shows the recently added data points at the end and scrolling will be reset to the end of the range whenever a new point is added.
By adding ChartZoomPanBehavior to the chart, you can scroll to see the previous datapoints.

AutoScrollingDeltaType

In DateTimeAxis, you can apply auto scrolling delta value in Years, Months, Days, Hours, Minutes, Seconds and Milliseconds by setting AutoScrollingDeltaType property. Default value of this property is Auto and the delta will be calculated automatically based on range.

C#

[C#]

chart.PrimaryAxis = new DateTimeAxis()
{
                AutoScrollingDelta = 3,
                AutoScrollingDeltaType = DateTimeDeltaType.Days
};

AutoScrollingMode

AutoScrollingMode property can be used to determine whether the axis should be scrolled from start position or end position. The default value of AutoScrollingMode is End.

C#

[C#]

chart.PrimaryAxis = new CategoryAxis()
{
      AutoScrollingDelta = 3,
	  
      AutoScrollingMode = ChartAutoScrollingMode.Start
};

Axis Crossing

Axis can be positioned anywhere in the chart area by using CrossesAt property. This property specifies where the horizontal axis should intersect or cross the vertical axis or vice-versa. Default value of CrossesAt property is null.

C#

[C#]

chart.PrimaryAxis  = new CategoryAxis() { CrossesAt = 0 };

chart.SecondaryAxis =  new NumericalAxis() { CrossesAt  = 8 };

Crossing a specific axis

CrossingAxisName property takes axis Name as input and determines the axis that used for crossing. By default, all the horizontal axes cross in primary Y axis, and all the vertical axes cross in primary X axis.

C#

[C#]

chart.PrimaryAxis = new CategoryAxis()
{
    CrossesAt = 0,

    Name = "PrimaryAxis",

    CrossingAxisName = "SecondaryAxis"
};

chart.SecondaryAxis = new NumericalAxis()
{
    CrossesAt = 2,

    Name = "YAxis",

    CrossingAxisName = "PrimaryAxis",
};

BubbleSeries series = new BubbleSeries()
{
    ...

    YAxis = new NumericalAxis()
    {
        CrossesAt = 8,

        Name = "SecondaryAxis",

        CrossingAxisName = "PrimaryAxis",
    }
};

Crossing in date time axis

For crossing in date time horizontal axis, date object should be provided as value for CrossesAt property of vertical axis.

C#

[C#]

    chart.PrimaryAxis  = new DateTimeAxis() { CrossesAt = 0 };

    chart.SecondaryAxis =  new NumericalAxis() { CrossesAt  = new DateTime(2003, 1, 1) };

NOTE

Axis will be placed in the opposite side if the value of CrossesAt property is greater than the maximum value of crossing axis. Axis will be placed in the default position if the value of CrossesAt property is less than the minimum value of crossing axis.

Positioning the axis elements while crossing

The RenderNextToCrossingValue property is used to determine whether the crossing axis should be placed at crossing position or not. The default value of RenderNextToCrossingValue property is true.

C#

[C#]

chart.PrimaryAxis = new CategoryAxis()
{
    CrossesAt = 20,

    RenderNextToCrossingValue = false
};

chart.SecondaryAxis = new NumericalAxis()
{
    CrossesAt = 5
};

Smart Axis Labels

Axis labels may overlap with each other based on chart dimensions and label size. The LabelsIntersectAction property of axis is used to avoid overlapping of axis labels. The default value of the LabelsIntersectAction is None; other available values are MultipleRows, Hide, and Wrap.

C#

[C#]

chart.PrimaryAxis.LabelsIntersectAction = AxisLabelsIntersectAction.MultipleRows;
