<p>By default the chart&apos;s canvas will use a 1:1 pixel ratio, unless the physical display has a higher pixel ratio (e.g. Retina displays).</p>
<p>For applications where a chart will be converted to a bitmap, or printed to a higher DPI medium it can be desirable to render the chart at a higher resolution than the default.</p>
<p>Setting <code>devicePixelRatio</code> to a value other than 1 will force the canvas size to be scaled by that amount, relative to the container size. There should be no visible difference on screen; the difference will only be visible when the image is zoomed or printed.</p>
