Gantt Chart Legend

Hi,

I'm currently working on a gantt chart and facing problem with the legend. I couldn't modify the legend accordingly. I have tried using the codes from Helphttp://help.sap.com/saphelp_nw04/helpdata/en/a8/1cd93f5e0f9015e10000000a155106/frameset.htm">Help> but I just couldn't produce my own legend. I would very much appreciate if any gurus can help me with the coding part. Currently the legend will take the label name from Series-> label.

Thanks in advance.
