Label format

Format numeric labels

By using the label-format property, you can format the numeric labels. Numeric values can be formatted with n (number with decimal points), c (currency), and p (percentage) commands.

CSHTML

<ej-pivot-chart id="PivotChart1">
    //Applying currency format to axis labels
    <e-primary-y-axis label-format="c" ></e-primary-y-axis>
    <e-size width="950px" height="460px"></e-size>
</ej-pivot-chart>

Following table describes the result when applying some commonly used label formats on numeric values:

Label Value	Label Format Property Value	Result	Description
1000	n1	1000.0	The Number is rounded to 1 decimal place
1000	n2	1000.00	The Number is rounded to 2 decimal place
1000	n3	1000.000	The Number is rounded to 3 decimal place
0.01	p1	1.0%	The Number is converted to percentage with 1 decimal place
0.01	p2	1.00%	The Number is converted to percentage with 2 decimal place
0.01	p3	1.000%	The Number is converted to percentage with 3 decimal place
1000	c1	$1,000.0	The Currency symbol is appended to number and number is rounded to 1 decimal place
1000	c2	$1,000.00	The Currency symbol is appended to number and number is rounded to 2 decimal place

Label format customization

By using the label-format property of e-primary-y-axis, you can add the category labels with a prefix and/or suffix.

CSHTML

<ej-pivot-chart id="PivotChart1">
    <e-primary-y-axis label-format="${value} K" ></e-primary-y-axis>
    <e-size width="950px" height="460px"></e-size>
</ej-pivot-chart>

Common axis features

Axis visibility

The axis visibility can be set by using the visible property of the respective axis.

NOTE

By default, the value of visible property is true in the pivot chart.

CSHTML

<ej-pivot-chart id="PivotChart1">
    //Disabling visibility of Y-axis
    <e-primary-y-axis visible="false"></e-primary-y-axis>
    <e-size width="950px" height="460px"></e-size>
</ej-pivot-chart>

Label customization

By using the font property of the axis, you can customize the font family, color, opacity, size, and font-weight of labels.

CSHTML

<ej-pivot-chart id="PivotChart1">
    //Customizing label appearance
    <e-primary-x-axis font-color="Blue" font-font-size="14px" font-font-family="Segoe UI" font-font-weight="Bold"></e-primary-x-axis>
    <e-size width="950px" height="460px"></e-size>
</ej-pivot-chart>

Label and tick positioning

Axis labels and ticks can be positioned inside or outside the chart area by using the axis-label-position and tick-lines-position properties. The labels and ticks are positioned outside the chart area, by default.

CSHTML

<ej-pivot-chart id="PivotChart1">
    //Customizing label and tick positions
    <e-primary-x-axis axis-label-position="Inside" tick-lines-position="Inside"></e-primary-x-axis>
    <e-size width="950px" height="460px"></e-size>
</ej-pivot-chart>

Grid lines customization

By using the major-grid-lines and minor-grid-lines properties of the axis, you can customize the width, color, visibility, and opacity of the grid lines.

NOTE

By default, the minor grid lines are not visible in the pivot chart.

CSHTML

<ej-pivot-chart id="PivotChart1">
    // Customizing grid lines
    <e-primary-x-axis major-grid-lines-width="5" major-grid-lines-visible="true" major-grid-lines-color="Blue" minor-ticks-per-interval="1" minor-grid-lines-width="25" minor-grid-lines-visible="true" minor-grid-lines-color="Red"></e-primary-x-axis>
    <e-size width="950px" height="460px"></e-size>
</ej-pivot-chart>

Tick line customization

By using the major-tick-lines and minor-tick-lines properties of the axis, you can customize the width, color, visibility, size, and opacity of the tick lines.

NOTE

By default, the minor tick lines are not visible in the pivot chart.

CSHTML

<ej-pivot-chart id="PivotChart1">
    // Customizing tick lines
    <e-primary-x-axis major-tick-lines-width="10" major-tick-lines-visible="true" major-tick-lines-size="15" major-tick-lines-color="Blue" minor-ticks-per-interval="1" minor-tick-lines-width="15" minor-tick-lines-size="25" minor-tick-lines-visible="true" minor-tick-lines-color="Red"></e-primary-x-axis>
    <e-size width="950px" height="460px"></e-size>
</ej-pivot-chart>

Inversing axis

The axis can be inversed by using the is-inversed property of the axis.

NOTE

By default, the is-inversed property is false in the pivot chart.

CSHTML

<ej-pivot-chart id="PivotChart1">
    //Inversing the X-axis
    <e-primary-x-axis is-inversed="true"></e-primary-x-axis>
    //Inversing the Y-axis
    <e-primary-y-axis is-inversed="true"></e-primary-y-axis>
    <e-size width="950px" height="460px"></e-size>
</ej-pivot-chart>

Placing axes at opposite side

The opposed-position property of the chart axis can be used to place the axis at opposite direction from its default position.

NOTE

By default, the opposed-position property is false in the pivot chart.

CSHTML

<ej-pivot-chart id="PivotChart1">
    //Placing axis at the opposite side of its normal position
    <e-primary-x-axis opposed-position="true"></e-primary-x-axis>
    //Placing axis at the opposite side of its normal position
    <e-primary-y-axis opposed-position="true"></e-primary-y-axis>
    <e-size width="950px" height="460px"></e-size>
</ej-pivot-chart>

Smart axis labels

When the axis labels overlap with each other based on the chart dimensions and label size, you can use the label-intersect-action property of the axis to avoid overlapping.

NOTE

By default, the label-intersect-action property is none in the pivot chart.

The following options that are supported for label-intersect-action property are:

• Rotate45
• Rotate90
• Trim
• MultipleRows
• Wrap
• Hide.

CSHTML

<ej-pivot-chart id="PivotChart1">
    // Avoid overlapping of x-axis labels
    <e-primary-x-axis label-intersect-action="MultipleRows"></e-primary-x-axis>
    <e-size width="950px" height="460px"></e-size>
</ej-pivot-chart>
