    Area Background

    Customize chart area grid bands

    You can provide different color for alternate grid rows and columns formed by the grid lines in the chart area by using the [alternateGridBand] property of the axis. The properties [odd] and [even] are used to customize the grid bands at odd and even positions respectively.

  • html
  • <ej-chart id="chartcontainer"  [primaryYAxis.alternateGridBand]="{even: {fill: '#A7A9AB',opacity: 0.1}">
        
    </ej-chart>

    GridBands

    Animation

    You can enable animation by using the [enableAnimation] property of the series. This animates the chart series on two occasions – when the chart is loaded for the first time or whenever you change the series type by using the type property.

  • html
  • <ej-chart id="chartContainer">
        <e-seriescollection>
            <e-series [enableAnimation]="true">
    		<-- Add points here-->
    		</e-series>
        </e-seriescollection>
    	
    </ej-chart>

    However, you can force the chart to animate series by calling the animate method as illustrated in the following code example,

  • html
  • <ej-chart id="chartContainer">
        <e-seriescollection>
            <e-series [enableAnimation]="true">
    		<-- Add points here-->
    		</e-series>
        </e-seriescollection>
    	
    </ej-chart>
  • javascript
  • //Dynamically animating Chart
    function animateChart(){
    
        //Calling the animate method for dynamic animation
        $("#chartContainer").ejChart("animate");      
            
    }

    Control the Speed of animation

    To control the speed of animation, you can use the animationDuration property in the series.

  • html
  • <ej-chart id="chartcontainer">
        <e-seriescollection>
            <e-series [enableAnimation]="true" [animationDuration]="2000">
    		<-- Add points here-->
    		</e-series>
        </e-seriescollection>
    	
    </ej-chart>
