Subplots: histogram and distplot

📊 Plotly Python
1

If I only plot histogram, I will get the plot like pic1. If I adjust ‘xbins’ or ‘nbinx’ in my code, it will just do nothing or disappear. But, the figure is still fine for me.

p.s. Hard, Clay and Grass data length are about 10000, 6600 and 2200

However, when I try to subplot both ‘figure_factory’ and ‘graph_objs’, I will get the plot like pic2. Each histogram doesn’t have same bins like pic3. Is there any idea to make it better?

By the way, I found that I have to disable the rug plot, or it will take out the space. Is it necessary to do this?
