hi
I am trying to make a legend using data from the output file (10 numbers in it). First I plot like this:
===========================================
int k = gly.AddPlot( crv, IDM_PLOT_SCATTER );
DataPlot dpLine = gly.DataPlots(k);
dpLine.Curve.Symbol.Type.nVal = 3;
===========================================
Thereafter I make a Legend like this
============================================
FILE *stream;
stream = fopen( name_path, "r" );
string head, sLegend, tmps;
head = "\g(t)\-(B)\+(c) / \g(t)\-(B)\+(l):";
sLegend=head;
for (m=0; m<10; m++)
{
fscanf( stream,"%s\n", cTmp);
string ts(cTmp, 5);
//fscanf( stream,"%s\n", tmps);
//string ts = tmps.Left(5);
printf("%s\n", ts);
sLegend.Format("%s\n\l(%d) %s",sLegend,m+1,ts);
}
fclose( stream );
gly.LT_execute("legend"); // create legend
GraphObject goLegend = gly.GraphObjects("legend");
if( goLegend.IsValid() ) goLegend.Text = sLegend;
=======================================================
I obtain this figure
What is the reason that the decimal numbers are not indexed with 1, 2 .... 10 in the Legend? Interestingly, this works fine if I use
dpLine.Curve.Line.Color.nVal = k;
where k runs from 1 to 10 in the for loop
What I do wrong?
thanks

I think the reason is that the graph layer has only one data plot. If this is true, the easiest solution is to change this line:
sLegend.Format("%s\n\l(%d) %s",sLegend,m+1,ts);
to:
sLegend.Format("%s\n\%d %s",sLegend,m+1,ts);

thank you Deanna,
I made this change
string head, sLegend, tmps;
head = "\g(t)\-(B)\+(c) / \g(t)\-(B)\+(l):";
sLegend=head;
for (m=0; m<10; m++)
{
fscanf( stream,"%s\n", cTmp);
string ts(cTmp, 5);
sLegend.Format("%s\n\%d:\t %s",sLegend,m+1,ts);
}
fclose( stream );
I get somthing like this which I hardly understand why
I affect every second Legend label. Why is that?

Hi Oliver,
Removing the extra '\' in front of %d will fix it... sLegend.Format("%s\n%d:\t%s",sLegend,m+1,ts);
