Is it possible to have 2 differents X scale ?

[Reuns]

Hi everybody,

I have this chart with :

• 4 bars (in green)
• 1 line matching the 4 bars with a different y-scale. (in red)
  This is ok.

Now need to add a new line with a lot of values (maybe hundred). But I only have the 4 first one. (matching the 7 bars)
Is it possible to do this ? And How ?
Thansk for your help.
