To draw a sphere in ActiveX is done, how can I extract 2D picture by certain value from the 3rd axes? Like cutting a banana.

Hi, all,

In Labwindows, I can use ActiveX to draw a surface in spherical coordinate system by the command CW3DGraphLib__DCWGraph3DPlot3DParametricSurface. X represents latitude (ranges 0~180), Y represents longitude (ranges 0~360), Z is altitude.

Right now, I need to draw a set of 2D graphs to tell the altitude pattern in different latitude. That's fix X at certain value and draw a 2D graph by Y and Z. Here I attach a sample picture, a desired picture. Could anybody tell me how can I make this graph in Labwindows?

Regards,

Pete

Maybe another way, since the data array is in hand, I can draw the Y-Z value in 2D picture. But I cannot find any 2D graph or chart have spherical coordinate system, all of the are cartesian system. Anybody know where to find a cartesian system 2D graph control?

Hi,

Take a look at the following example.  I believe the graph on the right on the user interface is what you are looking for.  Let me know if this helps or not.

C:\Program Files\National Instruments\CVI71\samples\userint\activex\3DGraphContours.cws

Hi, Tarry,

Thank you so much. The issue was resolved. But I still suggest to add the spherical coordinate system in Graph control in Labwindows.
