I'm trying to make a line graph with one Y-axis and two X-axis. As an example we'll use x-axis (1) as units, x-axis (2) as time and the y-axis is cost. I've tried and tried and I can't even figure out how to get a second x-axis.



Anyone know? Thanks in advance.

Hi,
it is difficult to understand what you like to achieve.
Could you perhaps attach an example (with a partly manually painted graph?), to explain how you want it to look like.

Kind regards
Bjorn
