I am exporting some data from my system. I want to visualize these datasets in an excel chart. I have found and old, closed question, where the solution was missing. The charts should redraw when i change a datafield, this is excel standard, i guess.
I think it may work this way:
Do you know how to do it with POI using Java? Especially the import of the chart as template?
Till now as the apache POI limitation is saying "You can not currently create charts. You can however create a chart in Excel, modify the chart data values using HSSF and write a new spreadsheet out. This is possible because POI attempts to keep existing records intact as far as possible".
However in my case, I have created a chart manually on excel sheet using Named Ranges, and using java, I am updating named ranges as per my requirement. Since the chart is based on named ranges so it also get updated.
