Chart Does Not Render with JavaScript Disabled

The Kendo UI Chart widgets requires JavaScript to run.


Enable JavaScript.

Chart Does Not Render on Mobile Device or Tablet

The browser must support SVG as the below ones do:

  1. iOS Safari 3.2 and later versions
  2. Opera Mobile 10.0 and later versions
  3. Android 3.0 and later versions


Layout Is Different in Exported PDF Files

Such issues are typically caused by the different fonts that are used on screen and in the PDF.

For display, the browser will substitute the selected font with whatever is provided by the system. During export, you will take the metrics from the actual font in use and determine the PDF layout from that. It is likely that the resulting PDF will be displayed with a different font, leading to layout and encoding issues.


The solution is to make the fonts available for embedding. This means that the fonts should be available as binary TTF files and registered for export.

This is demonstrated in the PDF Export demo on Charts as well.

The example below demonstrates how to embed fonts in exported PDF.

<button class='export-pdf k-button'>Save as PDF</button>

<div id="chart"></div>

    // Import DejaVu Sans font for embedding

        "DejaVu Sans"             : "https://kendo.cdn.telerik.com/2017.3.1018/styles/fonts/DejaVu/DejaVuSans.ttf",
        "DejaVu Sans|Bold"        : "https://kendo.cdn.telerik.com/2017.3.1018/styles/fonts/DejaVu/DejaVuSans-Bold.ttf",
        "DejaVu Sans|Bold|Italic" : "https://kendo.cdn.telerik.com/2017.3.1018/styles/fonts/DejaVu/DejaVuSans-Oblique.ttf",
        "DejaVu Sans|Italic"      : "https://kendo.cdn.telerik.com/2017.3.1018/styles/fonts/DejaVu/DejaVuSans-Oblique.ttf"
