[Gnuplot-info] Pivot charts

[Wilfried K. <wil...@gm...>]

Hi !

Is there any way to make pivot charts with gnuplot ?
While the rendering is not as perfect as with gnuplot (especially for latex
integration), this feature is quite cool for rendering complex data.
The basic idea is to provide several lines for the xtics.
Here is an example made with Excel 2010 :

I think such a result can be obtained using xtics (for hbw) and xmtics (for
BlockSize). But I don't really know how.
Furthermore, I do not have any clue on how to have more than two lines with
such a solution.

Does someone have any idea to do this with gnuplot ?

Thank you !

PS : here is an example data file corresponding to the above example.
I can change the format if required. This is just to give an idea.

PPS :
In my real cases, each hbw may not have the same set of BlockSize values.
