Hi
I am trying to transform revenue data from an XML file into an SVG line chart. The problem is that I am quite new to XPath and XSLT and whereas I can draw the grid for my chart I struggle drawing the lines using the data from the XML doc.
The XML look something like the one below, and I would like to have one chart for each product and in each chart having the time on the x-axis and chart the revenue by regions.
Any help on this is much appreciated.
Thanks
Peter
