So you have always wondered how on Earth one can make a real map with gnuplot. General binary data files fall into two basic classes and some files may be of both classes . They're not very .Ģ7.7 Tips 28 Help 29 History 30 If 31 Load 32 Lower 33 Pause 34 Plot splot can plot surfaces and contours in addition to points and/or lines. Additional input Here are some tips to keep in mind to get the most out of fit. New data preprocessing plot with boxes uses 2 or 3 columns of basic data. New plot styles with parallelaxes with table and labeled contours. Interactive mode is started by typing gnuplot on the command line All graphs have little meaning unless the axes have labels and the graph a title Left means the left side of the text is at that point right means the You can do many adjustments to the contour levels using the set cntrparam command. Except for the values of those two options these graphs are identical to figure C.1. In other words how can you best visualize a single output variable as a function of two In gnuplot you have essentially the same options cartographers have: Surface plots and contour plots are created using the splot command. to draw the contours: base draws the contours on the grid base where the . Similarly output can be piped to another application e.g. The plot command plots first the data as an image and adds to that the modified contour data (modified by contour.The UNIX MSDOS and VMS versions of gnuplot support commandline editing Ctrl Right Arrow For plots the x value may be omitted and for splots the x and y values may be omitted. Surface data of the function " sin(1.3*x)*cos(.9*y)+cos(.8*x)*sin(1.9*y)+cos(y*.2*x)" is plotted into "test.dat" in the x- and y-range given.īy using "set cont base" only the contour data of the function is written to the file "cont.dat"īy loading the contour.sh script the contour data in cont.dat is read and the labels for gnuplot are created. Plot 'test.dat' w ima, '<./contour.sh cont.dat 1 20 0' w l lt -1 lw 1.5 Set cntrparam level incremental -3, 0.5, 3

To create a contour plot like this two script files are needed.
