Rendering Modes

23 Jan 20181 minute to read

Chart supports following three rendering technologies:

  • VML
  • SVG
  • HTML5 canvas

VML

VML is used to render chart in lower versions of Internet Explorer such as Internet Explorer 7 and Internet Explorer 8. In these two browsers, SVG and Canvas are not supported, and VML is used by default.

Limitations:

  • Label rotation is not supported.
  • Animation is not supported.
  • Patterns are not supported.
  • Zooming and panning features are not supported.

SVG

SVG is used to render chart by default for all browsers except Internet Explorer 7 and Internet Explorer 8.

Canvas

You can switch between SVG and canvas rendering by using EnableCanvasRendering option. The canvas rendering is used in the following scenarios:

  • Plotting large number of data points.
  • Performing high frequency live updates.

The following code example illustrates how to enable HTML5 canvas rendering in chart.

  • CSHTML
    • <ej-chart id="container" enable-canvas-rendering="true">
  </ej-chart>

    Limitations:

    • Animation is not supported.
    • 3D charts are not supported.
