Can't set x-axis intervals

DanishReza

Hi guys, I am creating a birt reporting template where I need to create a histogram. In the chart, on x-axis, i want to plot maximum and minimum value coming out of my data source. Basically there is a coloumn which consists of several values. From these values, maximum and minimum values should be plotted on the x- axis.

The intervals should be (minimum-max)/10.

Can anyone help me to figure this out. How , what and where to write script for this?

Thanks :)
