Series values multiplier

Hi All,
I am using TeeChart for .NET (ver. 3.5.3146.24805).
I remember that in an older version of TeeChart (I worked with it it under Borland C++ Builder 5.0 some yeas ago) in the ValueList class there was a double property called "Multiplier" that was a multiplication factor for all the values inside the ValueList object, but I can't find it in the .NET version of TeeChart
....
Is something similar still available ?
Thanks.

Hi Luigi,
Do you mean the multiply function? There's an example of this at All Features\Welcome !\Functions\Standard\Multiply in the features demo. For more information about TeeChart functions please read Tutorial 7 - Working with Functions. Tutorials and demo can be found at TeeChart's program group.

Hi Luigi,
As an update, I see this property is obsolete now in the VCL version and it doesn't exist in .NET. Anyway I think multiply function could help or you could also use something like this:
Code: Select all
for (int i = 0; i < tChart1[0].Count; i++)
{
tChart1[0].YValues[i] *= 5;
}

Hi Narcís ,
If I understood correctly
the multiply function allows to multiply two series A and B and show the resulting function C...
In my case I should multiply all values of A for a constant value, keeping the original values inside the A series: is it possible to do this avoiding to add a point with value K (the multiply factor) into B for each point inside A, but simply one point of value K ?
Thanks.

Hi Luigi,
In that case you can use series marks and GetSeriesMark and GetAxisLabel event like this:
Code: Select all
public Form1()
{
InitializeComponent();
InitializeChart();
}
private double multiplyFactor = 5;
private void InitializeChart()
{
Steema.TeeChart.Styles.Bar bar1 = new Steema.TeeChart.Styles.Bar(tChart1.Chart);
bar1.FillSampleValues();
bar1.Marks.Visible = true;
bar1.Marks.Style = Steema.TeeChart.Styles.MarksStyles.Value;
bar1.GetSeriesMark += new Steema.TeeChart.Styles.Series.GetSeriesMarkEventHandler(bar1_GetSeriesMark);
tChart1.GetAxisLabel += new Steema.TeeChart.GetAxisLabelEventHandler(tChart1_GetAxisLabel);
}
void tChart1_GetAxisLabel(object sender, Steema.TeeChart.GetAxisLabelEventArgs e)
{
if (sender == tChart1.Axes.Left)
{
double tmp = Convert.ToDouble(e.LabelText) * multiplyFactor;
e.LabelText = tmp.ToString();
}
}
void bar1_GetSeriesMark(Steema.TeeChart.Styles.Series series, Steema.TeeChart.Styles.GetSeriesMarkEventArgs e)
{
double tmp = Convert.ToDouble(e.MarkText);
e.MarkText = Convert.ToString(tmp * multiplyFactor);
}
