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.

CSHTML

@(Html.EJ().Chart("chartContainer")

        //Providing a custom palette
        .Palette(pl => { pl.Add("grey"); pl.Add("skyblue"); pl.Add("orange"); })
        // ...
    )

NOTE

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

Built-in Themes

Following are the built-in themes available in the Chart

• Azure
• Azuredark
• Flatdark
• Flatlight
• GradientDark
• GradientLight
• Lime
• LimeDark
• Saffron
• SaffronDark

You can set your desired theme by using the Theme property. FlatLight is the default theme used in the Chart.

CSHTML

@(Html.EJ().Chart("chartContainer")

      //Using gradient theme
      .Theme(Syncfusion.JavaScript.DataVisualization.ChartTheme.GradientLight)
      // ...
    )

Point level customization

Marker, DataLabel and Fill color of each point in a series can be customized individually by using the Points collection.

CSHTML

@(Html.EJ().Chart("chartContainer")

      .Series(sr =>
      { 
        sr.Points(pt => {
            //Customizing marker and fill color of a point
            pt.X("0").Y(210).Fill("#E27F2D").Marker(mr => mr.Visible(true)).Add();
            //...
        })
       .Add();
          //...
      })
        // ...
    )

Series border customization

To customize the series border color, width and dashArray, you can use Series.Border option. The series border styles can be applied only to the column, bar and area type of series.

CSHTML

@(Html.EJ().Chart("chartContainer")

      .Series(sr =>
      { 
        sr.Border(border=>border.Color("blue").Width(2).DashArray("5,3")).Add();
        //...
      })
        // ...
    )

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.

CSHTML

@(Html.EJ().Chart("chartContainer")

      //Customizing Chart background
      .Background("skyblue")
      //Customize the chart border and opacity
      .Border(br=>br.Color("#FF0000").Width(2).Opacity(0.35))
      // ...
    )

Chart Margin

The Chart Margin property is used to add the margin to the chart area at the Left, Right, Top and Bottom position.

CSHTML

@(Html.EJ().Chart("chartContainer")

      //Change chart margin to left, right, top and bottom
      .Margin(mr=>mr.Left(40).Right(40).Bottom(40).Top(40)) 
      
      // ...
    )

Setting background image

Background image can be added to the chart by using the BackGroundImageUrl property.

CSHTML

@(Html.EJ().Chart("chartContainer")

      // ...
            
      //Setting an image as Chart background 
      .BackGroundImageUrl("images/chart/wheat.png")
      
      // ...
    )

Chart area background

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

CSHTML

@(Html.EJ().Chart("chartContainer")

      // ...
            
      .ChartArea(ca=>
          //Setting background for Chart area
          ca.Background("skyblue")
          )
      
      // ...
    )

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.

CSHTML

@(Html.EJ().Chart("chartContainer")

      // ...
            
      .PrimaryYAxis(axis=>
          //Customizing horizontal grid bands at even position
          axis.AlternateGridBand(band=>band.Even(en=>en.Fill("#A7A9AB").Opacity(0.1)))
          )
      
      // ...
    )

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.

CSHTML

@(Html.EJ().Chart("chartContainer")

      // ...

      .Series(
          //Enabling animation of series
          sr => { sr.EnableAnimation(true).Add(); 
      })
        // ...
    )

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

CSHTML

@(Html.EJ().Chart("chartContainer")

      // ...

      .Series(
          //Enabling animation of series
          sr => { sr.EnableAnimation(true).Add(); 
      })
        // ...
    )

JS

//Dynamically animating Chart
      function animateChart(){

           //Calling the animate method for dynamic animation
           $("#chartContainer").ejChart("animate");      
        
      }
