Dashboard: similar distances between values on X-axis

Hello,

I am used to have e.g. in a trendchart with n=10, 10 dots with a similar distance between them, independently of the date the measurements took place. The dates / time just appear for each value/measurement on the X-axis, but the distance between 2 measurements does not depend on the time span between these measurement . How can I program this?

Thx a lot, Michael
