I'm not familiar with any library that creates 3d graphs.

Surface charts are done using javascript and a webGL compatible browser. Not sure if the b4a Web view has that capability.

@KitCarlson very thanks , but before this post i try with it ( https://code.google.com/p/javascript-surface-plot/ ) and understand webview can't run and support webgl , maybe i can't work with it.

can you run webgl and javascript with webview ?
please give me example if you can .

i don't know why b4a don't want try to make good library for chart
i saw chart framework it's cool but it's not enough and complete.
i think b4a must imagine about future and try to strong this base it's very important in business.
b4a can take all the Android Market

I have tried the example on PC using jsFiddle, it worked. I have a similar need like you.

oh only on your pc ? not your android device ?

 

[KitCarlson]

PC only.

My need is for a hobby, but I am considering $100 USD in job offer forum, for b4a, b4j ways to do it. I will share with all members.

I think someone might have the skills to do it.

very very thank you
i wish b4a do it before another one
we are not alone , maybe someone need it before we said and maybe will need in future

Here's a 3D landscape generated with LibGDX. Hope that helps.

@Informatix very thanks , it's very very good

but how can add axis titles, grids and plot color intensity?
Is it possible and can you help everyone in this forum need it?

I don't have the time to improve my example. Drawing the axis can be done with the same method used to draw the landscape, and drawing the title can be done with a bitmapfont, as usual. If you want to fill the grid with colors, either you draw a colored mesh between lines but that requires some knowledge of OpenGL, or you draw points to fill the empty space between lines but that will be horribly slow.
