Integration with semantic MW
Hi Thank you for this extension, really nice. I want to ask if there's a plan of integrating this to SMW? This is way better than the Semantic result format graph format (google)  printer

Gérard 18:58, 2 December 2009 (UTC) We're glad to hear from you and that you're pleased with the extension. We have no plans in that direction, at least not yet.


 * I'd also appreciate efforts towards integration with SMW!! - Bernhard

Large Dataset Line Graphs
Nice extension, thanks for adding it. Using the pChart classes gives much more swishy renders than using GnuPlot. There is one problem I have not been able to solve for my planned implementation though. When trying to create a line graph with a large amount of data, e.g.:

the x-axis labels become overlaid ontop of each other until all you get is a grey line - i.e. there is no setting to say "show 5 x labels", giving me just "0, 100, 200, 300, 400, 500", on the x-axis. The extension seems to be hardwired to show every x-label as it has been entered in to the data.

This is a bit of a show-stopper for me as I need to plot 500+ point datasets as line graphs with useable x-axis ticks. At the moment I am going to have to stick with GnuplotBasic as it has the configuration to do that. Have I missed some obvious control parameter or is this not yet possible with PC4MW?

Hello, We will look in to this, don't know if the pChart library supports this option. Gérard 03:58, 8 June 2010 (UTC)

Decimals ignored in axis labels
Hi, I'm having a problem where the labels for the y-axis are not showing up properly when I use floating point values.

 0.1 0.2 0.3 0.4 0.5 

With the specified code above, the labels for the y-axis come out like this: http://img15.imageshack.us/f/33312048.png/
