Hi,

I have an issue with filled area series and the AreaLines.
I added an Area series to my chart and filled it up with a blue transparent gradient.
Then I set the visible property of the AreaLines to false. But in the transparent region I still see the AreaLines. Probably because they are not drawn with the same transparency.

My sample code:

Code: Select all

m_tchart.Axes.Bottom.Grid.Visible = false;

Steema.TeeChart.Styles.Area area = new Steema.TeeChart.Styles.Area();
m_tchart.Series.Add(area);
fillWithSampleValues();

area.Gradient.Visible = true;
area.Gradient.Transparency = 75;
area.Gradient.StartColor = System.Drawing.Color.Blue;
area.Gradient.EndColor = System.Drawing.Color.Blue;

area.LinePen.Visible = true;

area.AreaLines.Visible = false;

What can I do about is? Is this a known issue?

Thanks,
Marijke.

Hi Marijke,

I've just answered you pro support question. Here is the answer

I've opened a new ticket in the defect list to be fixed in future releases (TF02014691).

Thank you.

Hi Marijke,

After investigating this we've noticed that the most appropriate way to work with transparency gradients within the area series is setting:

Code: Select all

serie.GradientRelative = false;
