Adding legend to series

[Anthony]

Hi,

I would ike to add strings for the legend of my series.

My code looks like:
Steema.TeeChart.Styles.Line line;
for (int iPar=0;iPar<noPars;iPar++)
{
// parameter iPar
iTime= 0; // only first time level
float[] xValues = new float[noLocs];
float[] yValues = new float[noLocs];
line = new Steema.TeeChart.Styles.Line();
tChart1.Series.Add(new Steema.TeeChart.Styles.Line());
for (int iLoc=0;iLoc<noLocs;iLoc++)
{
// location iLoc
xValues[iLoc] = iLoc;
yValues[iLoc] = gsSeries[iPar,iLoc,iTime];
}
tChart1.Series[iPar].Add(xValues,yValues);
tChart1.Series[iPar].Chart = tChart1.Chart;
tChart1.BackColor = Color.Azure;
}

but how and where to add the legend *gsParameters[iPar]* defined in

string[] gsParameters;

So, *gsParameters[iPar]* is the legend string for series with number *iPar*.

Thanks,

Hi Antoon,

how about using :
tChart1.Series[iPar].Add(xValues,yValues,gsParameters[iPar]);
?

Hi Pep,

Thanks for your quick reply, but it did not work.

The compiler complained about invalid arg 1,2 and 3. I guess, because there is no overloaded method taking System.Array, System.Array and string (legend) as arguments.

I found some overloaded method taking a string, but that's is the string connected to a data point in series, but not the legend for the complete series.

Some *further* help would be nice !

Thanks,
Antoon

Hi Antoon,

I'm sorry, I mistake me. In that case, using Arrays you should use the StringList as in the following example :

Code: Select all

private void Form1_Load(object sender, System.EventArgs e)
{
float[] xValues = new float[5]; 
float[] yValues = new float[5]; 
Steema.TeeChart.Styles.StringList labels = new Steema.TeeChart.Styles.StringList(5);
labels[0] = "a1";
labels[1] = "a2";
labels[2] = "a3";
labels[3] = "a4";
labels[4] = "a5";		
line1.Add(xValues,yValues);
line1.Labels = labels;
}

Hi Anthony,

As you have already populated your series it may be enough for you using:

Code: Select all

tChart1.Series[iPar].Title=gsParameters[iPar];

Hi,

It works great !

BTW, last 2 questions ..

1) If I maximize my window including the TeeChart component, the TeeChart component is not resized . Why ??

2) Normally I have two or more series connected to both vertical axes, but sometimes there is only one single series to display. In that case I only see one (left) axis. How can I establish that I always see two vertical axis ?

Thanks.

Hi Anthony,

You should set TChart anchors editing it's properties in view designer mode.

2) Normally I have two or more series connected to both vertical axes, but sometimes there is only one single series to display. In that case I only see one (left) axis. How can I establish that I always see two vertical axis ?

You can force both vertical axis to appear using the code above for the remaining series.

Code: Select all

tChart1.Series[1].VertAxis=Steema.TeeChart.Styles.VerticalAxis.Both;

Hi,

Still a question about the TChart' s anchor properties you mentioned.

If I am in design mode with the form including my TChart component, and then right-click and go to Properties in the Context Menu, then the TeeChart editor is launched. In this case I expect a Property Window, with an attribute *anchor* for editing, or is the *anchor* part of TeeChart editor ? And if so, where (on which tab page) can I find that property ??

Thanks again.

Hi Antoon,

You will find the anchor property in the VS.NET property editor for the TChart component you dropped in your form, not in the TeeChart Editor.
