We already have one to resize the height of the paragraph result.
So there might be some conflicts

Yes, I've noticed it, but it only shows up when there is a table/graph in view. Should I try merge it here, or this there?

It's not too shocking to have both resize handles, however the resize graph height doesn't work anymore.
You might also want to rebase. (since we merged some graph width fix)
Maybe having one handle for both height and width could be better

Have updated this PR, instead of having multiple resize handles. Merged it into one.

I have tested and it works really well. Thanks @prabhjyotsingh for really improvement.

One thing is, resize drag handle is shown in report mode. But i think it more sense to hide there. What do you think?

Could you also un-commit the note.json?

Found plenty of issues:

1. Scrollbar when code line is too long on notebook refresh/load
   

2. Resize to a size too small error
   
   

3. opposite effect resize
   

Thanks for the review and finding bugs;

1. Scrollbar when code line is too long on notebook refresh/load - Fixed
2. Resize to a size too small error - Fixed by having a minimum height, tried to use jQuery resizable minHeight but that cannot be used in out use case. Hence, fixed with following

var adjustHeight = elem.height() - extraHeight;
if (adjustHeight < 100) {
   scope.updateWidth({height: 100, width: Math.ceil(elem.width() / colStep)});
} else {
   scope.updateWidth({height: adjustHeight, width: Math.ceil(elem.width() / colStep)});
}

3. opposite effect resize - With above two this also got fixed.

Does this looks ok ?

@prabhjyotsingh I will test it again tomorrow, sorry for the delay

Tested, the bug are gone.
There is now a minimum size on the output.
However, would it be possible to apply the same limit to the dragging?
Right now, it looks like you can resize below that minimum height:

Thanks @corneadoug for the feedback and a providing me with a lot of test cases.
Have merged this with the latest master, which seems to solve the bug for me.
Let me know if this works.

I've found weird behaviors.
I can make paragraph width larger than the notebook width and resize proxy is displayed incorrectly.
Please take a look following screenshot

Tested and LGTM.
Thanks @prabhjyotsingh for really useful feature

Merge if there're no more discussions

Re-tested, +1
