Upgrading from 5.1.1 to 5.2 causes plots not be drawn

Upgrading from 5.1.1 to 5.2 causes plots not be drawn, with no errors, but the console acts as if it has been drawn.

E.g.

JSROOT.draw(dom_element, root_object);

works for 5.1.1 and 5.2.0, with the same console output:

Extract basic data type 3 TH1::EBinErrorOpt

What does this use behind the scenes to draw the plots? Has there been some change to the JSROOT.draw method which might cause it to draw in the official example but not in our application?

It depends how you use this method. Basic functionality is the same. Only return value is changed. If you want to to access painter instance, you should use forth callback parameter now:

For some reason, with 5.1 the canvas was being resized, whereas with 5.2 it’s not resized when JSROOT.draw is called.

Probably, you are right. At some point I disable setting of canvas pixel size to html element - it may conflict with layout of other html elements. Dimension of div element for canvas should be provided by user.
