Series format -> Marks ->Margins query.

[TonyVSUK]

If you are in the TChart editor, and select a line series, followed by "Marks", and then "Margins", you have the option of setting the units to "Percent Font", "Percent Size" or "Pixels".

But in my TeeChartDefines.h file, I only have
// EErrorWidthUnits
const unsigned long ewuPercent = 0;
const unsigned long ewuPixels= 1;

Am I missing one? Shouldn't there be ewuPercentFont, ewuPercentSize and ewuPercentPixels?

Hi Tony,

In TeeChart AX v2010 Beta I can see:

Code: Select all

// EMarginsUnits
const unsigned long maPercentFont = 0;
const unsigned long maPercentSize = 1;
const unsigned long maPixels = 2;

Are these valid in version 8.0.0.7?

Hi Tony,

No, and neither in TeeChart AX 8.0.0.8. It's new in TeeChart v2010.

ok, so back to the original question, if you are in the TChart editor, and select a line series, followed by "Marks", and then "Margins", you have the option of setting the units to "Percent Font", "Percent Size" or "Pixels".

How do you set these in code given there are only two options (ewuPercent and ewuPixels)?

Hi Tony,

What about using values (0, 1 and 2) instead of constants?

[TonyVSUK]

I can use constants easily enough, but that does not answer the question.

The following constants are in TChart 8.
ewuPercent = 0;
ewuPixels= 1;

How do I set the units to "Percent Font" or "Percent Size" when the only option is "Percent"?

Hi Tony,

Sorry if my explanation was not clear enough. What I meant is that even constants are not defined you can use their numeric value, for example:

Code: Select all

	m_Chart1.Series(series1).GetMarks().GetMargins().SetUnits(2);

0: Sets margins to PercentFont.
1: Sets margins to PercentSize.
2: Sets margins to Pixels.

[TonyVSUK]

0: Sets margins to PercentFont.
1: Sets margins to PercentSize.
2: Sets margins to Pixels.

Do these work in TChart 8? If they do, it means the following is incorrect.

I just want to be sure before I let my customers use it.

// EErrorWidthUnits
const unsigned long ewuPercent = 0;
const unsigned long ewuPixels= 1;

Hi Tony,

Yes, it does. I did the tests with v8 here.
