Does anyone know if dbPro supports non integer steps like QuickBasic did? If not why not.

I want to be able to plot math functions in 2k and 3d.

I also need to use a transformation matrix to be able to display the 4 cartesian quadrants.

Any help would be appreciated.

1. yes. just use a float variable and use the step command.

???????? what do you mean?

Part of solving the problem is actually noticing that the problem is there in the first place

Thanks, got it! Just trying to plot basic math functions in 2d (sine, cosine, etc).

For the transformation matrix I'll have to review Eulers angles.

What I was looking for is how do I define the cartesian coordinates;
|
-+ | ++
|
--------------
|
-- | +-
|


Like so

For sin etc. all it is is multiply by -1 to flip the plot.

Thanks again
