Gnuplot question: how to plot 3D points as colored points in map view?

I have a simple gnuplot question. I have a set of points (list of x,y,z values; irregularly spaced, i.e. no grid) that I want to plot. I want the plot to look like this:
- points in map view (no 3D view)
- color of each point should depend on its z-value.
- I want to define my own color scale
- plot should contain a little legend box in the form of a color bar listing what z-value corresponds to what color

I tried pm3d, but it seems it only handles gridded data, i.e. x,y's on a regular grid, or at least displays them as such. I just want to see the individual points (no interpolation).

Thanks for your help here.

gnuplot: map view with black and white for 0/1 in the 3rd column

Hi, I am using gnuplot to plot a 3D plot with "set view map". My data looks like ====== X Y Z ====== 100 200 0 200 300 1 200 200 0 . . . The third column only has either 0 or 1. How do I generate a map view plot that will have black (white) for 0 (1)? Thanks, Gaurab (0 Replies)

matching points in Gnuplot

Does anyone know how can one draw lines between 2 sets of data for the same point. let's say that the three points (x1,y1) = (1,2) (4,5) (8.9) became: (x2,y2) = (3,6) (6,4) (4, 0) so if I want to plot these points and match every (x1,y1) with the corresponding (x2,y2), how can I do it?...

NAME
plot: openpl et al. - f77 library interface to plot(3X) libraries. SYNOPSIS
subroutine openpl() subroutine erase() subroutine label(str) character str*(*) subroutine line(ix1, iy1, ix2, iy2) subroutine box(ix1, iy1, ix2, iy2) Draw a rectangle and leave the cursor at ( ix2,iy2). subroutine circle(ix, iy, ir) subroutine arc(ix, iy, ix0, iy0, ix1, iy1) subroutine move(ix, iy) subroutine cont(ix, iy) subroutine point(ix, iy) subroutine linemd(str) character str*(*) subroutine space(ix0, iy0, ix1, iy1) subroutine clospl() DESCRIPTION
These are interface subroutines, in the library -lf77plot, allowing f77 users to call the plot(3X) graphics routines which generate graphic output in a relatively device-independent manner. The f77 subroutine names are the same as the C function names except that linemod and closepl have been shortened to linemd and clospl . See plot(5) and plot(3X) for a description of their effect. Only the first 255 character in string arguments to label and linemd are used. This library must be specified in the f77(1) command before the device specific graphics library; for example, to compile and load a FOR- TRAN program in prog.f to run on a Tektronix 4014 terminal: f77 prog.f -lf77plot -l4014 See plot(3X) for a complete list of device specific plotting libraries.
