7 Jun 20174 minutes to read

EjChart supports horizontal and vertical striplines.

Horizontal Stripline

You can create horizontal stripline by adding the stripline in the vertical axis and set visible option to true. Striplines are rendered in the specified start to end range and you can add more than one stripline for an axis.

TS

this.stripLine = [
    //Create horizontal Stripline using vertical Axis
    {
        //Enable Stripline
        visible: true,
        start: 30,
        end: 40,
    },
           // ...
];

HTML

<ej-chart id="chartcontainer" [primaryYAxis.stripLine]="stripLine">
</ej-chart>

Vertical Stripline

You can create vertical stripline by adding the stripline in the horizontal axis and set visible option to true.

TS

this.stripLine = [
          //Create vertical Stripline using vertical Axis
          {
              //Enable Stripline
              visible: true,
              start: 3,
              end: 7,
          },
           // ...
];

HTML

<ej-chart id="chartcontainer" [primaryXAxis.stripLine]="stripLine">
</ej-chart>

Customize the Text

To customize the stripLine text, use the text and font options.

TS

this.stripLine = [
          //Create horizontal Stripline using vertical Axis
          {
              //Customize the stripLine text and font styles
              text: 'High Temperature',
              font: { size: '18px', color: 'white' }
              // ...  
     }];

HTML

<ej-chart id="chartcontainer" [primaryYAxis.stripLine]="stripLine">
</ej-chart>

Text Alignment

Stripline text can be aligned by using the textAlignment property.

TS

this.stripLine = [{
    //Set stripLine text alignment to top position
    textAlignment: 'middletop',
    // ...                         
}];

HTML

<ej-chart id="chartcontainer" [primaryYAxis.stripLine]="stripLine">
</ej-chart>

Customize the Stripline

To customize the stripLine styles, use the color, opacity, borderWidth and borderColor properties.

TS

this.stripLine = [{
    //Customize the StripLine rectangle
    color: '#33CCFF',
    borderWidth: 2,
    opacity: 0.5,
    borderColor: 'red',
    // ...
}];

HTML

<ej-chart id="chartcontainer" [primaryYAxis.stripLine]="stripLine">
</ej-chart>

Change the Z-order of the stripline

Stripline zIndex property is used to display the stripLine either behind or over the series.

TS

this.stripLine = [{
    //Change stripLine zIndex
    zindex: 'over',
    // ...
}];

HTML

<ej-chart id="chartcontainer" [primaryYAxis.stripLine]="stripLine">
</ej-chart>
