![]() ![]() ![]() In an other data i have a lot of values in y and only a few values in x, like 8x100, what should i do in this case also? I use Gnuplot 5.0 patchlevel 3 on Ubuntu 16.04LTS. 1.3 Does gnuplot have anything to do with the FSF and the GNU project 1.4 What does gnuplot offer. I tried to use othes values at "set dgrid3d", but it didn't work. and then i plot with the splot command: splot 'Contours.txt' using 1:2:3 notitle with pm3d,\ 'MCoordPlain.txt' with points nocontour using 1:2: (0) pt 7 The resulted plot is only the contour 2D projection but with no points on it and with no errors. Splot 'abs.txt' u 1:2:3 with lines title 'abs'Īs you can see, I don't have a lot of point (only 8x12), then the surface plotted is like this: Surface, but this is not the kind of surface I want, because it is not getting all the point, and i would like a softened surface, without this peaks. I understood that i have to grid the data, and i tried to use splot in this way: It is freeware (though not necessarily open-source, as the FAQ notes.) Im not sure if the situation has changed, as the development files are now being hosted at Sourceforge->gnuplot. The plot command would have created six points, whereas the splot command comes up with only five different regions for every axis. Theres a story about this, but you should probably read about this for yourself at the gnuplot FAQ. Note, that the result differs already from the plot command. 1 the result of plotting the data just with splot, without interpolation is shown. However since the surface mesh, from which contours are derived, connects sequentially corresponding points, the effect of an irregular grid on a surface plot is unpredictable and should be examined on a case-by-case basis. I have a x, y, z data, like points in a 3D space: Points_3D set pm3d map splot 'heatmapdata.txt' matrix In Fig. gnuplot requires only that the number of points be the same for each block. I am a begginer in gnuplot and I've been trying to plot a surface. Gnuplot is distributed with a large set of demonstration scripts. I am from Brazil, so my english is terrible. Demos for gnuplot version 5.4 (pngcairo terminal) See also the demo output for the SVG and canvas terminals.
