Custom Color Palette

The Chart displays different series in different colors by default. You can customize the color of each series by providing a custom color palette of your choice by using the [palette] property.

HTML

<ej-chart id="chartcontainer" [palette]="[ 'yellow', 'skyblue', 'orange', 
                                 'yellow', 'cyan', 'lightBlue', '#ff0ade']" >
   
   </ej-chart>

NOTE

The Color palette is applied to the points in accumulation type series

HTML

<ej-chart id="chartcontainer" theme="gradientlight">
   
   </ej-chart>

Point level customization

Marker, data label and fill color of each point in a series can be customized individually by using the points collection.

HTML

<ej-chart id="chartcontainer">
    <e-seriescollection>
        <e-series>
		 <e-points>
		   <e-point x="10" [y]="50" fill="#E27F2D" [marker.visible]="true">
           </e-point>
         </e-points>
		</e-series>
    </e-seriescollection>
</ej-chart>

Series border customization

To customize the series border color, width and dashArray, you can use series.border option.

NOTE

Series border can be applied to all the series (except Line, Spline, HiLo, HiLoOpenClose and StepLine series).

HTML

<ej-chart id="chartcontainer">
    <e-seriescollection>
        <e-series>
		 <e-points>
		   <e-point x="20" [y]="80"  border.color="blue" [border.width]= 2
                                                  border.dashArray= "5,3" >
           </e-point>
         </e-points>
		</e-series>
    </e-seriescollection>
	
</ej-chart>

Chart area customization

Customize chart background

The Chart background can be customized by using the background property of the Chart. To customize the chart border, use border option of the chart.

HTML

<ej-chart id="chartcontainer"  background="skyblue"  [border.width]="2" 
                                               [border.opacity]="0.35" >
   
</ej-chart>

Chart Margin

The Chart [margin] property is used to add the margin to the chart area at the left, right, top and bottom position.

HTML

<ej-chart id="chartcontainer"  margin.left="80" margin.right="80" margin.top="40"
                                                             margin.bottom="80">
    
</ej-chart>

Setting background image

Background image can be added to the chart by using the [backGroundImageUrl] property.

HTML

<ej-chart id="chartcontainer"  backGroundImageUrl="wheat.png">
    
</ej-chart>

Chart area background

The Chart area background can be customized by using the [background] property in the chart area.

HTML

<ej-chart id="chartcontainer"  chartArea.background="skyblue">
    
</ej-chart>

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>

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>
