How 2 make different shapes on histograms?

Hello Everyone,
I have an excel histogram chart, and I'm looking to make it in 2 forms:
For example stripes for one type of data and ordinary for other type of data.
Someone knows how to do that?

HI
I do not understand.
Could you be so kind as to attach an example of what you have and what you would like to obtain, perhaps handmade.

For example at the attachment:
I want some of the histograms to be stripes, and some remain smooth.
How can I do that?

Thanks

I think it can only be done with VBA.
This is the code:

Hi,
Thank you very much for the help.
But is there another way to do this except VBA? I'm asking this because I'm not familiar with VBA.
