hershey-font-gnuplot renders Hershey font text in. Works very nice with the font type I used in here. The Hershey fonts are a collection of vector fonts developed circa 1967 by Dr. The choice of the right type of font is vital so as gnuplot to display correctly not only the letters someone wants, but also other things as the superscripts in labels. If the font path does not complain with errors, then propably you have chosen it correctly, and it will display the fonts you want.Įvery time someone makes a change and wants to save that change to the "name_of_file.png", someone should retype the (*) command first, then give the changes (for example set another xlabel) and finaly replot. Set output "name_of_file.png" (*) -> see below Set term png enhanced font "/usr/share/fonts/truetype/msttcorefonts/Times_New_Roman.ttf" If you want to have hellenic, or some other fonts in your labels, you have to type the path of the fonts that you want to use: Now, in order to save the above "project" to a png file it suffices to type: Iv)with f(x)=#, where # is a number, we plot a line parallel to the x axis Iii)with replot we plot a second plot to the same plot (hope this was clear) Gnuplot is a portable command-line driven graphing utility for Linux, OS/2, MS Windows, OSX, VMS, and many other platforms. For example: set key font ',20' would set the size of the font to 20. Ii)the lt #, where # is a number, gives the color of the line, The font for the key can be set in gnuplot 4.4. I)the linewidth shows "how big" the line will be Replot "file2" u 1:2 w l linewidth 4 lt 1 (the process took place in gutsy gibbon, I think that it will work in most linux boxes) Which allows to choose the fonts we want to use in gnuplot labels and also to extract a plot with multiple sub-plots in a display file. The postscript terminal uses its own font. The following is an example of employing these commands: gnuplot> set ylabel 'labely'. Furthermore, a default font for these drivers may be set via the environmental variable GNUPLOT DEFAULT GDFONT. This is a how to based on here (in hellenic language): Also, we can rotate labels as well as set their font and size. In order for gnuplot to find the font the environmental variable GDFONTPATH should be able to look where the fonts are installed. Searching further about the error it seems that gnuplot cannot find a font that is needed. GdImageStringFT: Could not find/open font Options are 'nocrop enhanced medium size 640,480 ' I have tried to set both the size for postscirpt files inside gnuplot or via the convert command, yet to no avail. I get the output in png and the label as it should be, yet with the exception that the resolution is not as good as cretaing a png file from gnuplot. Maybe you propose to install something else? 1) Every time I type the plot command inside gnuplot I get a preview of my plot in a new window.Ģ) I have installed many tex packages from synaptic, yet to no avail as far as png files from gnuplot are concerned. Please write to gnuplot-beta mailing list if you know any other useful links.
