Changing colors on series using C# (.NET) and Labels/Legends

[User (Legacy)]

Hello again,

I have two questions today.

1) First a problem when trying to change colors on ceratin series in the

chart. It works fine for constant lines, but nothing happens when I try it

on the series. I use the following code:

chart.OpenDataEx(CfxCod.COD_VALUES, 4, dsLength);

  ...

  (insert the values)

  ...

chart.CloseData(CfxCod.COD_VALUES);

Then I try to change the colors using this code:

chart.OpenDataEx(CfxCod.COD_COLORS, 2, 0);

  chart.Series[2].Color = uiColRed;

  chart.Series[3].Color = uiColGreen;

chart.CloseData(CfxCod.COD_COLORS);

Is this the correct way of doing it? The series do change colors, but not to

the ones I chose, and I can't change them to any other colors.

2) Is there a way to use "labels" with series, like with constant lines? I

know I can use legends but I'd like the text inside the chart, just

above/below a series. Is an annotation the only solution to this?

TIA,

Rolle

NB. I'm using version Cfx IE 5.5 with C# (.NET)

1) What is uiColRed ? you need to pass an OLE color like RGB(255,0,0)

2) The series legend only shows in the series legend box. It can not be

displayed in the chart itself. You can indeed use annotation objects to do

this.

Yes, I am passing the correct value for the color red with uiColRed. But

it's not of type RGB(255,0,0) since this doesn't work in .NET/C#.

It works fine for constant lines. But when I try to change the color for a

series it doesn't matter what I use, it doesn't care. I have even tried not

sending any color at all, and I still get the color chosed by Chart FX. So

in other words, it doesn't matter if I set any color when using

chart.OpenDataEx(CfxCod.COD_COLORS, 2, 0) because it changes automatically

to some standard color. If I don't use CfxCod.COD_COLORS it uses some other

standard color. The following code gives the same result (pseudo):

chart.OpenDataEx(CfxCod.COD_COLORS, 2, 0);

  chart.Series[2].Color = uiColRed;

  chart.Series[3].Color = uiColGreen;

chart.CloseData(CfxCod.COD_COLORS);

chart.OpenDataEx(CfxCod.COD_COLORS, 2, 0);

  // Do nothing

chart.CloseData(CfxCod.COD_COLORS);

But it works when I do this:

chart.ConstantLine[0].LineColor = uiColRed;

chart.ConstantLine[1].LineColor = uiColGreen;

But I am not sure on how to use chart.OpenDataEx(CfxCod.COD_COLORS, 2, 0),

so I might be doing something wrong..? It should work in .NET too...right..?

Rolle

Sorry, I didn't realize this before but you are doing:

chart.OpenDataEx(CfxCod.COD_COLORS, 2, 0);

  chart.Series[2].Color = uiColRed;

  chart.Series[3].Color = uiColGreen;

chart.CloseData(CfxCod.COD_COLORS);

This code allocates two (2) colors only, Series[0] and Series[1] but then

you are trying to assign Series[2] and Series[3]. If you have 4 series you

need to do:

chart.OpenDataEx(CfxCod.COD_COLORS, 4, 0);

  chart.Series[0].Color = ???;

  chart.Series[1].Color = ???;

  chart.Series[2].Color = uiColRed;

  chart.Series[3].Color = uiColGreen;

chart.CloseData(CfxCod.COD_COLORS);
