Hi Nathaniel ,
Thanks for your reply
Did you mean adding multiple dimensions like this....
double[][] lineData =3D {d1,d2,d3};
....blah blah
axisChartDataSet =3D new AxisChartDataSet(lineData, lineLegendLabels,
linePaints, ChartType.LINE, lineChartProperties);
dataSeries.addIAxisPlotDataSet(axisChartDataSet);
but the problem here is=20
1. The length of dataseries d2 and d3 may not be same
2. also they may represent diff times on the x axis , This is because
they r transactions which occur sequentially And I don't want to insert
a NAN value for all the missing values because that would put gaps in
the lines of the line chart=20
Eg.. there is no value for point 4 on the x axis for D3 but there is one
for point 5 which is just after 43 seconds . So they fit into the
overchart but are a subset of the same
X axis Y axis
Time D1 D2 D3
