KitCarlson Active Member Licensed User Longtime User Jan 4, 2015 #1 I have the need for a 3D surface chart, to show a two dimensional array of data values. This is for a hobby project, for showing fuel and ignition timing tables. The data Z, would be indexed by X, Y. Here is a javascript example using webGL. https://code.google.com/p/webgl-surface-plot/ I will pay $100 USD via paypal, for one working example in b4a. I will share with b4x members. If $100 is not enough for work required, perhaps others with 3D chart needs, will help contribute too.

derez Expert Licensed User Longtime User Jan 5, 2015 #2 This can be done with my library Body3D (after slight modification of array sizes) here https://www.b4x.com/android/forum/threads/3d-bodies-four-libraries.48373/ It can be rotated by the user If you want I can do it for you. I tried to run it by BodyGl but it fails due to heavy workload on the OpenGl . Attachments surface.png 38.4 KB · Views: 867 surface1.png 46.1 KB · Views: 897 Last edited: Jan 5, 2015

KitCarlson Active Member Licensed User Longtime User Jan 5, 2015 #3 That is a good start. Is it possible to add axis titles, grids and plot color intensity?
derez Expert Licensed User Longtime User Jan 5, 2015 #4 Yes. Color intensity is already in the picture.
