Remove the white space on x axis

Hi experts,

I am new with plotly. I am trying to remove the horizontal space in x axis to form a Renko chart.
Unfortunately, I could not find any solution. Have anyone dealt with the same requirement?

Also, do you know any way to plot the same x axis category with different data not stacked or overlayed (please see the screenshot)? I have tried with multiple categories but it did not work.

Your help is greatly appreciated.
