How to set maximum 100% for TopN visuals?

I have created a TOPN visual for percentage CPU usage, I created a visual in TSVB - > Time series, done all settings for axis min and max values. once its shows 100% max on the x-axis, I change the visual to TOPN. but it's not showing usage bar with respect to 100%. for 4% itself bar is totally filled.

How can I change it max as 100%, and bar should fill with respect to 100%
