Thank you Svetlin.
What I'm looking for is not an option to download as an image, but to get a thumbnail - a tiny copy,
to be used on the screen as a representation of the chart.
I found an option of the method drawImage which deals with canvas, but I can't use it since the chart is
not a video/img/canvas etc. (btw - an option of chart as a canvas won't solve it).
Anyways, that is what I need and I'm afraid the option is not available for Angular Kendo chart...
Any idea will be appreciated!
