First, I'm running 0.9.21, so if the problem described below is fixed, just
let me know.
I'm trying to extend DualAxisDemo5 to support four(4) series (0-based).
My example below almost works, but it overlays the two middle bars (numbers
1 and 2). I added null series as follows (referencing the 'real' series):
series 0: on the right;
series 1,2: on both sides;
series 3: on the left
[The axes placement and mappings work fine; I have axes 0,3 on the left, and 1,2 on the right.]
Here's the code:
