This is another one, which used to work in earlier builds of version 3.

I have my TeeChart (MasterChart) object with some series. I also have another TeeChart (TempChart) object in memory with just one series. I have a line of code like:

Code: Select all

    MasterChart[seriesIndex].Assign(TempChart[0]);

With latest builds, after I run this code, first, not all the properties are assigned (I assign Line series with Pointer.Visible = true to another Line series and Pointer.Visible stays false). Second, if I write the following code:

Code: Select all

    MasterChart[seriesIndex].Marks.Visible = true;

or just try to set MasterChart[seriesIndex].Color by using your editor - at best nothing happens (but usually I am getting "Object reference not set to an instance of an object" error).

Hi UserLS,

We have fixed this issue (TF02014555) for next v3 and 2009 releases. Please notice that you should use Clone instead of Assign, for example:

Code: Select all

			Steema.TeeChart.Styles.Line line1 = new Steema.TeeChart.Styles.Line(tChart1.Chart);
			line1.Pointer.Visible = true;
			line1.FillSampleValues();

			Steema.TeeChart.Styles.Line line2 = line1.Clone() as Steema.TeeChart.Styles.Line;
			line2.FillSampleValues();

			tChart1.Series.Remove(line2);
			tChart2.Series.Add(line2);

We could also reproduce the Marks.Visible error (TF02014577), which has also been fixed.

Regarding the color issue, it works fine for me here.

The problem I had: I already had my series added to different charts and Clone() did not like it, when I tried to add it to a different chart... Anyway, I have written my own Assign() method, which actually works and assigns all the properties (not just a subset) and makes sure that all of them make sense for the target series type (since I can assign a bar series to a pie, for example).
