Below is the link, i have plotted histogram and bellcurve.
1. I want to change/redraw chart based on x-axis min and max values , so that histogram and normalized curve should also change.
2. I have seen highchart has some default zoom option by drag and drop, but here in the below link, i am unable to do it. can you please help in that ?
