Hi Michael: I am not familiar with gnuplot (last time I used it was in 1996 or so) so could you explain your use case in a lot more detail? Obviously, you have some data to plot, but at this point I don't know for sure whether it is 2D or 3D data or whether it is experimental data, something you can generate from a simple function, or something that is the result of extensive calculations. In the first case, I would read the experimental data into whatever language you prefer to work with (Python, C, or whatever). In the second and third cases, you can probably call PLplot directly from the programme that produced the data if the calculation is done in one of our many supported computer languages. Are you sure you want to create a plot similar to example 18? The only way that would make sense is if your data is in the form of a line (as opposed to a surface) in 3D space. If that happens to be the case, then first try to get an unmodified version of example 18 to work in the language of your choice, and we can take it from there.

The Python program below should give you roughly the same thing, though
I'm not sure exactly which feature of gnuplot plot you were trying to
recreate. The trick to getting the box at the bottom of the plot is that
you have draw it yourself.

Hazen, Thank you for the suggestion. That worked a lot better (I'm using Java). The trouble I have is with specifying the world coordinates of the viewport and then setting up the window for 3D in a programmatic way, which is what led to my original problem. What strategy would you (or others) suggest for letting plwind and plw3d float based on the supplied data. Thanks. Michael C. Robbeloth Consultant Data Science Automation Inc.

Robbeloth Michael, I don't think you need to worry too much about plwind unless you are planning on changing the azimuthal viewing angle of the plot, just find some setting that you like and it should be good. For plw3d you'll need to figure out the min and max of the data for each axis, then use that (or some multiple of it) to set the min/max for the various axises, leaving the first 3 parameters as 1.0 (or whatever your preference is). -Hazen |
