[reportlab-users] Combining Bar and Line Charts

[Kostadin Atanasov]

Yep!

In fact Andy's response helped - I was able to combine the two charts -
line and bar...
I see you have implemented two legends - one for the line, one for the bar,
which is a future question I will have :).

For the moment I am struggling with more basic questions:
1. How to make the bar labels show in the middle of the bar segment (each
bar has let's say 3 segments - it's a stacked vertical bar chart). The only
thing I figured is to calculate the nudge (or dy) manually and apply it on
each label. Is there a parameter, e.g. barLabelPosition = 'middle'... would
be much more elegant solution.

2. How to make the label show a value different than the underlying data (I
want to calculate % separately and pass them as labels). I saw the
property barLabelArray, but passing values in the same shape as the data
list doesn't seem to have any effect. What am I missing? Is there a setting
or a flag that prevents barLabelArray from working?

Your help is much appreciated!
