Patch for 8 y axes on a QwtPlot
You seem to have CSS turned off.
Please don't fill out this field.
I'm extremely interested in this patch. Does it work with the current qwtplot release? Will it ever be included in the main development trunk?
I think multiple-axis plots are essential to many applications. I have many problems using qwtplot exactly because of the 2 y-axes limit, which prevents me from effectively compare the shape of many curves at the same time.
Plots "panels" are not as effective as multi-y plots for this task.
As the 2-y ax limit is blocking my work, I am also considering to normalize all the curves, then draw additional axes out of the widget. But this would be slower, very complex and not as accurate as native multi-y graph.
This patch doesn't make sense anymore - beside you have to stay with an outdated Qwt version. Instead a maintained branch is available from https://sourceforge.net/p/qwt/code/HEAD/tree/branches that is planned to be released as Qwt 6.3
