Hi, Mike.

You might try checking the TeeExport.pas unit, especially the InternalTeeEmailFile routine which actually calls the MapiSendMail routine.

Hi.

Try using the is instead of typeof. Something like this:

Code: Select all

...
  if (ts is Steema.TeeChart.Styles.Line)
  { ... }
  else if (ts is Steema.TeeChart.Styles.Gantt
  { ... }
  else if (ts is Steema.TeeChart.Styles.Point)
  { ... }
...

Hi.

#1 has just been added to Smith series (DrawLegendShape method). The fix will be included in next maintenance release.

Hi, Gabor. The problem is PDF export does not (yet) support transparency. The end result is it also cannot interpret Color.Transparent as "transparent brush" i.e. no brush. The workaround for your problem is to set the AreaBrush.Visible property to false if Color is Color.Transparent. This way no ar...

Hi.

Several ways to do it. If you're only displaying/using series title in legend text, then the easiest solution is to change series Title property. Something like this:

Code: Select all

tChart1.Series[0].Title = "Series1Title";
tChart1.Series[1].Title = "Series2Title";
...

Hi. First thing to do is check if each "row" has the same number of elements i.e. if _result.Wall[m].Length are the same for all m's. Colorgrid will work correctly only if x,y is a 2D grid where all rows have the same number of columns. If this is not the case, you'll have to create missing values (...

I think any additional coding (including filtering of points before displaying) would most likely create an overhead i.e. the fastline series would become slower.

Marjan

Hi.

What's the total number of points per series ? I'm guessing here but most likely the number of points is large (compared to number of pixels i.e. chart size). Does the same problem occur when you reduce the number of points in series ?

Marjan

Would be nice if you could display a couple of points on a fastline for printing purposes. I understand your concern but you could implement it the same a markers where you can set a property for the number of markers to display If you only need to display couple of points, then the best solution i...

Forgot the link to article (sorry):

The article was originally written for VCL version, but the same principles apply for .NET version as well.

Hi, Berndt. Strange. PixelDownSample should work fine i.e. it should reduce the number of displaying points to managable size. Using a simple algorithm PixelDownSample replaces group of points with the same pixel x coordinate with two or four points. But you must be aware of the fact the downsamplin...

Hi.

Only the series with their's ParentChart property set to (valid) chart will show up in the datasource combo box. I guess one dirty way to remove some series from selection is to set their's ParentChart property to nil:

Code: Select all

Series2.ParentChart := nil;

Hi. Which TeeChart and Delphi version are you using ? Perhaps the problem is left axis automatic scaling was accidentally disabled at design time. Try reseting it with the following code: acurve.GetVertAxis.Automatic := true; Also, check if all yvalues are not the same. Another thing to check is if ...

Marjan

Hi.

It might help setting point series ColorEach property to true:

Code: Select all

origin.ColorEach = true;

Hi.

As Watermark over chart ? Yes, several ways to do it. You can either paint the image directly on tChart.Chart.Graphics3D in tChart OnAfterDraw event. Alternatively you can also use Annotation tool (with bacground image) or ChartImage tool.
