No worries. Be aware of WebGL context limits. 16 per browser (chrome), 2 per browser on mobile. I would suggest you do the webgl check once on app startup then re-use the result.

Hi Saksham,

At the moment SciChart.js requires either WebGL 1 or 2 in the browser, there is no way to use SciChart without hardware acceleration.

Find out what browsers are supported in our documentation page:

Minimum Browser Requirements
SciChart.js is a cutting-edge next-generation JavaScript Chart Library. As a result, we are using the latest technologies to draw our fast, real-time and interactive JavaScript charts.
Minimum requirement for deployment of an application with SciChart.js is your browser must support WebAssembly (wasm) and WebGL 1 (preferably WebGL 2).
A full table of which browsers are supported can be found at the caniuse.com website.

The good news is, 97.94% of browsers support at least WebGL 1 and this number is increasing all the time.

To detect if WebGL is supported, you can add some code similar to this to your application.

function webgl_support () { 
   try {
    var canvas = document.createElement('canvas'); 
    return !!window.WebGLRenderingContext &&
      (canvas.getContext('webgl') || canvas.getContext('experimental-webgl'));
   } catch(e) {
     return false;
   }
 };

If this function returns false then don’t display a SciChart.js chart, but instead an error message.

We could show a better error message than the above in SciChart.js if webgl is not found. I’m going to add a low priority task to our backlog for this. In the meantime, please use the workaround above.
