using Borland C++ Builder 6.0. have a TChart object and using it as a series. on the X-Axis, we have date values which on the initial display of the data, display across several days (ok, so far). when we select a segment of the data (zoom), and keep zooming until we are looking at about 1 days wort...

It would be really great if TeeChart can draw closed 3D shapes. For example - torus: Parametric presentation is X = (q+r*cos(v))*cos(u) Y = (q+r*cos(v))*sin(u) Z = r*sin(v) where q = 10 r = 2 v = -3.14..3.14 u = -3.14..3.14 or see http://en.wikipedia.org/wiki/Torus Something like Grapher for MacOSX....

Hello guys.

I have a chart... I have added a series with some values.

Now I want to add an annotation, which will located at a certain value on the X-Axis.

What I want it the ability to find the Pixel-X of a certain value of the X-Axis.

How is that possible?

Thanks,

Ron.

Hi,
I´m trying to create a surface with a surfaceNearest tool.
The problem is that I need my chart to use OpenGL, since there are
3d Bubbles on it.

But it seems that the tool stops working when I turn my chart into OpenGL

Is there a way to avoid this ?

Thanks

Hi, I just tried to install the Teechart pro VCL 7.07 for C++ Builder 6. The Multi_Language in the demo does not work when I selected with different language from the language list box. In addition, the source code from the source code tab doesn't give enough information how to add or drop languages...

think I've sussed it, set coloureachpoint:=true and in the ongetpointerstyle event set the .valuecolor[valueindex] for each point. Amazing how posting a request for help prompts the brain into coming up with an idea

I have a Tchart (Pro 7.06) with a map style display which has hundreds of Tlineseries, each having 2000-3000 x,y points. At each point there is measured a third variable which I need to colour code by value, so if the variable is say 1.0 I would rdaw point x1,y1 as red, then if point x2,y2 is 2.5 I ...

Hi Narcís Ok thanks a lot, i think i'll have to modify my values to fit the canvas bounds. Thanks for your time. King Regards Dimitrios Hi Dimitrios, I did: procedure TForm1.Draw3D1Paint(Sender: TObject; const ARect: TRect); begin Draw3D1.Canvas.Sphere(-4129749,190627496,0,10); Draw3D1.Canvas.Sphere...

Hello Narcis Thanks for the suggestions but it didn't make any difference. Could you please try the following scenarion and see if it works? In a new project add a TDraw3D and a TeeCommander components to the form. Then simply on the OnPaint Event of the TDraw3D try to draw on the canvas (e.g. Draw3...

Hello, I am trying to make some 3D objects using the TDraw3D. When i draw an object it doesn't appear on the canvas. Probably because the actuall coordinates of the points of the object are pretty huge numbers and very far away from the current view of the canvas. I was wondering, is there any way t...

How can I produce a scatter chart with lines joining successive points in the order they are input, as for example in MS EXCEL'S XY (Scatter) chart type.

Thanks Nick

The answer to null points in a OpenGL surface is to set NumXValues and NumZValues first and then just don't AddXYZ the points that are null.

Paul

Thanks for the info.

What you suggest works only if OpenGL is turned off.

I need OpenGL on for speed reasons.

Any other suggestions ?

I'm creating a 3d surface, adding surface points with AddXYZ(x,y,z), the documentation says null (y) surface points are supported.

How do I add them ?

There doesn't seem to be an AddNullXZ(x,z)

Suggestions ?

Later,
Paul

Hi Narcis I have found a solution (see below) using the AssignValues method. procedure TForm1.SmoothingClick(Sender: TObject); var Tfunctiona: TSmoothingFunction; i: Integer; begin Tfunctiona:=TSmoothingFunction.create(self); Series22.SetFunction(Tfunctiona); Tfunctiona.Interpolate:=false; Tfunction...
