Problem solved thanks for your help.

Hi Narcís I don't think you have understood if I load a previously save chart series into a current chart the series defined by the loaded graph has a NULL pointer. I can't add new data to the graph. I added the following lines into the demo progam in the Export SVG to test this as part of your demo...

I would like for the end user to define the look of there chart using the build in Edit Chart functions. I can save and load OK but when I try to added data after loading the Series1 is no longer defind ie the pointer to Series1 is Null. How do I redefine this so that it will works as it did before ...
