Thanks for your response. Right now I have written some test code which uses the ruport/util library in Ruby. I am able to output an SVG graph from the code, if we can glue this into FX I will look to integrate the ruport graphs class.
I will try and get this into FX now but if anyone has any suggestions I look forward to a response.

I would like to ask a few questions about the 'charts' example which is included with the newest release of FX. I like the idea of producing a chart like this however this one appears to need an internet connection to work (i assume to gather formating?).
Right. It uses the Google Chart API, which depends on being able to access the network-based Google Chart service.
I have a large array full of data and I would like to plot a graph based on two of the fields in the array e.g. date againist vs event. Is there a way I can do this similar to the example given in charts.rb. I would like it to work offline and simply draw a line or bar graph based on two sets on data (date along the botton and event frequency up the side). Can this be done?
I hope some others on the list will chime in on this one. There's no built-in charting library for FXRuby, but if there are any existing Ruby libraries that can be used to produce chart graphics, we can probably find a way to feed their output into an FXRuby image.
Hope this helps,
