how to get canvas from chart in v2?

[mastnova]

I need to get a canvas to convert into image and print into pdf. In previous 1.x versions, I used the onReady event to get the plot and then plot.chart.getCanvas() to get the canvas. But in version 2.x this method no longer exists. How can I get the canvas?

to convert canvas to image use - plot.toDataUrl('image/png')
