Yes, we can.
(1) Right click the axis, and click edit axis.
(2) In General tab, change the Range to fixed and starting from 0.2 and 0.4 respectively.
Please also see the workbook.
Hope it helps.

We can do it, I want it to be controlled by a parameter. When required I can able to trim the chart from 20%, 40% etc with the help of a parameter. That is why I include that slider in the attachment.
