Axes

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
  • <body>
        <div ng-controller="PivotChartCtrl">
            <div id="PivotChart1" ej-pivotchart e-primaryYaxis="primaryYAxis"/>
        </div>
        <script>
            angular.module('PivotChartApp', ['ejangular']).controller('PivotChartCtrl', function ($scope) {
                ///..
                $scope.primaryYAxis = {
                    //... 
                    //Applying currency format to Y-Axis labels
                    labelFormat: 'c'
                };
            });
        </script>
    </body>

    Following table describes the result on 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 labelFormat property of e-primaryYaxis, you can add the category labels with prefix and/or suffix.

  • html
  • <body>
        <div ng-controller="PivotChartCtrl">
            <div id="PivotChart1" ej-pivotchart e-primaryYaxis="primaryYAxis"/>
        </div>
        <script>
            angular.module('PivotChartApp', ['ejangular']).controller('PivotChartCtrl', function ($scope) {
                ///..
                $scope.primaryYAxis = {
                    //... 
                    //Adding prefix and suffix to Y-axis labels
                    labelFormat: '${value} K'
                };
            });
        </script>
    </body>

    Common Axis Features

    Axis Visibility

    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 PivotChart.

  • html
  • <body>
        <div ng-controller="PivotChartCtrl">
            <div id="PivotChart1" ej-pivotchart e-primaryYaxis="primaryYAxis"/>
        </div>
        <script>
            angular.module('PivotChartApp', ['ejangular']).controller('PivotChartCtrl', function ($scope) {
                ///..
                $scope.primaryYAxis = {
                    //... 
                    //Disabling visibility of Y-axis
                    visible: false
                };
            });
        </script>
    </body>

    Label Customization

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

  • html
  • <body>
        <div ng-controller="PivotChartCtrl">
            <div id="PivotChart1" ej-pivotchart e-primaryYaxis="primaryYAxis"/>
        </div>
        <script>
            angular.module('PivotChartApp', ['ejangular']).controller('PivotChartCtrl', function ($scope) {
                ///..
                $scope.primaryYAxis = {
                    //Customizing label appearance
                    font:
                    {
                        fontFamily: 'Segoe UI',
                        size: '14px',
                        fontWeight: 'bold',
                        color: 'blue'
                    }
                };
            });
        </script>
    </body>

    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.

  • html
  • <body>
        <div ng-controller="PivotChartCtrl">
            <div id="PivotChart1" ej-pivotchart e-primaryYaxis="primaryYAxis"/>
        </div>
        <script>
            angular.module('PivotChartApp', ['ejangular']).controller('PivotChartCtrl', function ($scope) {
                ///..
                $scope.primaryYAxis = {
                    //Customizing label and tick positions
                    labelPosition: 'inside',
                    tickLinesPosition: 'inside'
                };
            });
        </script>
    </body>

    Grid Lines Customization

    By using the majorGridLines and minorGridLines 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 PivotChart.

  • html
  • <body>
        <div ng-controller="PivotChartCtrl">
            <div id="PivotChart1" ej-pivotchart e-primaryYaxis="primaryYAxis"/>
        </div>
        <script>
            angular.module('PivotChartApp', ['ejangular']).controller('PivotChartCtrl', function ($scope) {
                ///..
                $scope.primaryYAxis = {
                    //Customizing Grid Lines
                    majorGridLines:
                    {
                        color: 'blue',
                        visible: true,
                        width: 5
                    },
                    minorTicksPerInterval: 1,
                    minorGridLines:
                    {
                        color: 'red',
                        visible: true,
                        width: 5
                    }
                };
            });
        </script>
    </body>

    Tick Lines Customization

    By using the majorTickLines and minorTickLines 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 PivotChart.

  • html
  • <body>
        <div ng-controller="PivotChartCtrl">
            <div id="PivotChart1" ej-pivotchart e-primaryYaxis="primaryYAxis"/>
        </div>
        <script>
            angular.module('PivotChartApp', ['ejangular']).controller('PivotChartCtrl', function ($scope) {
                ///..
                $scope.primaryYAxis = {
                    //Customizing Tick Lines
                    majorTickLines:
                    {
                        color: 'blue',
                        visible: true,
                        width: 10,
                        size: 15,
                    },
                    minorTicksPerInterval: 1,
                    minorTickLines:
                    {
                        color: 'red',
                        visible: true,
                        width: 20,
                        size: 15
                    }
                };
            });
        </script>
    </body>

    Inversing Axes

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

    NOTE

    By default, the isInversed property is false in PivotChart.

  • html
  • <body>
        <div ng-controller="PivotChartCtrl">
            <div id="PivotChart1" ej-pivotchart e-primaryYaxis="primaryYAxis"/>
        </div>
        <script>
            angular.module('PivotChartApp', ['ejangular']).controller('PivotChartCtrl', function ($scope) {
                ///..
                $scope.primaryYAxis = {
                    //... 
                    primaryXAxis:
                    {
                        //Inversing the X-axis
                        isInversed: true
                    },
                    primaryYAxis:
                    {
                        //Inversing the Y-axis
                        isInversed: true
                    }
                };
            });
        </script>
    </body>

    Placing Axes at Opposite Side

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

    NOTE

    By default, the opposedPosition property is false in PivotChart.

  • html
  • <body>
        <div ng-controller="PivotChartCtrl">
            <div id="PivotChart1" ej-pivotchart e-primaryXAxis="primaryXAxis" e-primaryYaxis="primaryYAxis"/>
        </div>
        <script>
            angular.module('PivotChartApp', ['ejangular']).controller('PivotChartCtrl', function ($scope) {
                ///..
                $scope.primaryYAxis = {
                    //Placing Y-axis at the opposite side of its normal position
                    opposedPosition: true
                };
                $scope.primaryXAxis = {
                    //Placing X-axis at the opposite side of its normal position
                    opposedPosition: true
                };
            });
        </script>
    </body>

    Smart Axis Labels

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

    NOTE

    By default, the labelIntersection property is none in PivotChart.

    The following options that are supported for labelIntersection property are:

    • rotate45
    • rotate90
    • trim
    • multipleRows
    • wrap
    • hide.
  • html
  • <body>
        <div ng-controller="PivotChartCtrl">
            <div id="PivotChart1" ej-pivotchart e-primaryXAxis="primaryXAxis" e-primaryYaxis="primaryYAxis"/>
        </div>
        <script>
            angular.module('PivotChartApp', ['ejangular']).controller('PivotChartCtrl', function ($scope) {
                ///..
                // Avoid overlapping of X-axis labels
                $scope.primaryXAxis = {
                    labelIntersectAction: 'multipleRows'
                };
            });
        </script>
    </body>
