![]() ![]() Note that until a plotĬommand is given, the window will not be created. Select (or create) a new figure with id n. Open windows, since on the backend gnuplot also can not close windows. Manually set the location of gnuplot executable.Ĭlose all gnuplot active connections. There are also several handy operations for decorating plots which areĬommon to many of the plotting functions. Png, eps or pdf files or creating plots directly on png or eps or pdf files.

To have Europe in the center we set also the viewport. Offset between the lowest z vlaue an the xy-plane. We arrange the appeareance of the plot by setting the xy-plane to the lowest z value in order to avoid an Also we want to have a non transparent world, therefore we need hidden3d. We have to tell Gnuplot to map the data on a sphere and using angle values in degree. ![]() The 3D plot needs a little more settings. Set lmargin screen 0 set bmargin screen 0 set rmargin screen 1 set tmargin screen 1 set style line 2 lc rgb '#c0c0c0' lt 1 lw 2 unset border Therefore we first add a gray line style, unset the border and arrange the figure margins. We can also easily draw a whole globe in 3D from the given data. 2 The 2D plot of the world edited with Inkscape This and a solution to convert the lines to dashed versions is also mentioned in the plotting the world entry.įig. Especially the dashed line of the grid is not created in the right way, even though the dashed option is used for the terminal. The last thing I would like to mention is the problem, that the output of the svg terminal is slightly different from the pngcairo terminal. 1 and why we should do this:ġ) change the default colors to more pleasant ones and make the lines a little bit thicker set style line 1 lc rgb '#8b1a0e' pt 1 ps 1 lt 1 lw 2 # - red set style line 2 lc rgb '#5e9c36' pt 6 ps 1 lt 1 lw 2 # - greenĢ) put the border more to the background by applying it only on the left and bottom part and put it and the tics in gray set style line 11 lc rgb '#808080' lt 1 set border 3 back ls 11 set tics nomirrorģ) add a slight grid to make it easier to follow the exact position of the curves set style line 12 lc rgb '#808080' lt 0 lw 1 set grid back ls 12 In the following I will have a look at the things we have to do to reach Fig. 2 Default output of the pngcairo terminal ( code to produce this figure, data) ![]()
