Discrete data contained in a file can be displayed by specifying the name of the data file (enclosed in quotes) on the plot or splot command line. Together with the function strlen you should be able to build your solution to automatically process your data in gnuplot and place the newline character where you want it (e.g. gnuplot> plot sin(x)/x gnuplot> splot sin(xy/20) gnuplot> plot sin(x) title 'Sine Function', tan(x) title 'Tangent' 3.2 Plotting Data. Set label 1 system("cat stringvar.tmp") at graph 0.1, graph 0.9 (foo eq 'A' & foo ne 'X') ? "true" : "false"
#GNUPLOT TITLE CODE#
# Miscellaneous neat things you can do using the string variables code Titlestring = foo1.\n.foo2 #make new title string with newline characterįor more details refer to the string variable demo script of gnuplot: Length2 = sprintf("%1.d", length / 2) #round halved down string length to find center charįoo1 = substr(foo, 0, length2) #get first half of stringįoo2 = substr(foo, length2, length) #get second half of string In summary you would have something like foo = "my data" Here is a complete list of gnuplot functions: With strlen("string") you can find the length of your string and then with substr("string",begin,end) you could split your strings. Also note that gnuplot saves you the need to retype the name of the data file over again by interpreting. If you can't edit the data in your file, you could use the string functions in gnuplot. The overall plot title appears along the top edge. It is important to note, that \n is only considered by gnuplot if you have "string" instead of 'string'. Otherwise you need to manually enter the title and add the \n at your desired position. Gnuplot will recognize the \n and break the line at that point.
You should edit the data in your file and insert a \n in the field where the title is parsed from.
