Tachart : Accessing to series ...

[Gozaki]

Hello !

Newcomer to Lazarus, I've a question regarding the Tachart Component.
How to do something like that :

form1.chart1.Series.Items[nbrtrace].AddXY(i*step,j,'',clRed);

Thanks

Could you explain what does it mean?

[Gozaki]

Sure !

I'm reading a binary file (using streams) containing interleaved oscilloscope traces. There is 16 traces in the file. I've thus created a chart with 16 series. I would like to add points to the chart series using such code :

For i:= 0 to tracenumber do
 for j:=0 to xypointsnumber do
    chart.serie.items.addXY (x,y,'',clred)

Thanks

Perhaps you can add them like this:

Code: [Select]

TBarSeries(chart1.Series[nbrtrace]).AddXY(i*step,j,'',clRed);
