HTML5 multi-axis chart

[jl_m]

Hi,

I want to build a stacked column graph.
It is mandatory to have 3 measures but I only need 2, so I created :
- measure 1 : stacked as column bars
- measure 2 : always null (created just for the system to have its 3 measures)
- measure 3 : lines

The result is odd because the lines on measure 3 seems to not be on the same scale.
In fact, even if points on the 2 lines have the same value, they are not one of top of the other, they are separated.
What could explain this behaviour?

Thanks a lot for any help
