Label format

Format numeric labels

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

  • html
  • <template>
      <div>
        <ej-pivot-chart e-primary-y-axis.bind="primaryYAxis">
        </ej-pivot-chart>
      </div>
    </template>
  • javascript
  • export class BasicUse {
           constructor() {
                //...
                primaryYAxis:
                {
                    //...
                    //Applying currency format to Y-Axis labels
                    labelFormat: 'c'
                }
            }
        }

    The following table describes the result of applying some commonly used label formats to 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 labelFormat property of the primaryYAxis, you can add the category labels with prefix and/or suffix.

  • html
  • <template>
      <div>
        <ej-pivot-chart e-primary-y-axis.bind="primaryYAxis">
        </ej-pivot-chart>
      </div>
    </template>
  • javascript
  • export class BasicUse {
           constructor() {
                //...
                primaryYAxis:
                {
                    //...
                    //Adding prefix and suffix to Y-axis labels
                    labelFormat: '${value} K'
                }
            }
        }

    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 the visible property is true in the pivot chart.

  • javascript
  • export class BasicUse {
           constructor() {
                //...
                primaryYAxis:
                {
                    //...
                    //Disabling visibility of Y-axis
                    visible: false
                }
            }
        }

    Label customization

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

  • html
  • <template>
      <div>
        <ej-pivot-chart e-primary-x-axis.bind="primaryXAxis">
        </ej-pivot-chart>
      </div>
    </template>
  • javascript
  • export class BasicUse {
           constructor() {
                //...
                primaryXAxis:
                {
                    //Customizing label appearance
                    font:
                    {
                        fontFamily: 'Segoe UI',
                        size: '14px',
                        fontWeight: 'bold',
                        color: 'blue'
                    }
                }
            }
        }

    Label and tick positioning

    Axis labels and ticks can be positioned inside or outside the chart area by using the labelPosition and tickLinesPosition properties. The labels and ticks are positioned outside the chart area, by default.

  • javascript
  • export class BasicUse {
           constructor() {
                //...
                primaryXAxis:
                {
                    //Customizing label and tick positions
                    labelPosition: 'inside',
                    tickLinesPosition: 'inside'
                }
            }
        }

    Grid lines customization

    By using the majorGridLines and the minorGridLines properties of the axis, you can customize the width, color, visibility, and opacity of the grid lines.

    NOTE

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

  • javascript
  • export class BasicUse {
           constructor() {
                //...
                primaryXAxis:
                {
                   //Customizing Grid Lines
                    majorGridLines:
                    {
                        color: 'blue',
                        visible: true,
                        width: 5
                    },
                    minorTicksPerInterval: 1,
                    minorGridLines:
                    {
                        color: 'red',
                        visible: true,
                        width: 5
                    }
                }
            }
        }

    Tick lines customization

    By using the majorTickLines and the minorTickLines properties of the axis, you can customize the width, color, visibility, size, and opacity of the tick lines.

    NOTE

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

  • javascript
  • export class BasicUse {
           constructor() {
                //...
                primaryXAxis:
                {
                   //Customizing Tick Lines
                    majorTickLines:
                    {
                        color: 'blue',
                        visible: true,
                        width: 10,
                        size: 15,
                    },
                    minorTicksPerInterval: 1,
                    minorTickLines:
                    {
                        color: 'red',
                        visible: true,
                        width: 20,
                        size: 15
                    }
                }
            }
        }

    Inversing axes

    Axes can be inversed by using the isInversed property of the respective axis.

    NOTE

    By default, the isInversed property is false in the pivot chart.

  • javascript
  • export class BasicUse {
           constructor() {
                //...
                primaryXAxis:
                {
                    //Inversing the X-axis
                    isInversed: true
                },
                primaryYAxis:
                {
                    //Inversing the Y-axis
                    isInversed: true
                }
            }
        }

    Placing axes at opposite side

    The opposedPosition property of the chart axis can be used to place the axis in the opposite direction from its default position.

    NOTE

    By default, the opposedPosition property is false in the pivot chart.

  • javascript
  • export class BasicUse {
           constructor() {
                //...
                primaryXAxis:
                {
                    //Placing X-axis at the opposite side of its normal position
                    opposedPosition: true
                },
                primaryYAxis:
                {
                    //Placing Y-axis at the opposite side of its normal position
                    opposedPosition: true
                }
            }
        }

    Smart axis labels

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

    NOTE

    By default, the labelIntersectAction property is none in the pivot chart.

    The following options are supported for the labelIntersectAction property:

    • rotate45
    • rotate90
    • trim
    • multipleRows
    • wrap
    • hide.
  • javascript
  • export class BasicUse {
           constructor() {
                //...
                primaryXAxis:
                {
                    labelIntersectAction: 'multipleRows'
                }
            }
        }
