[reportlab-users] Re: two Y-axes on bar/line chart

[Marc Stober]

Hi Gert,

It is pretty easy to do this by creating two separate chart objects and
overlaying them on the same drawing.

Hope this helps,
Marc

Hi

Does anyone know if it is possible to get Reportlab to generate a bar/line
chart
with two Y-axes?

I.e. Say I want a chart that shows the relationship between the amount of
coffee
consumed and the number of lines coded by a development team.

I want:
1) X-axis -> time
2) Primary Y-axis -> the number of lines coded
3) Secondary Y-axis (right hand side of the chart) -> litres of coffee
consumed

Because the units of the Y-axes differ they cannot be plotted on the same
axis,
thus the need for the primary and secondary axis.

Has anyone ever done something similar with ReportLab?

Regards
Gert Steyn
