One title for multiplot in gnuplot - Stack Overflow

november 2017 by aries1988

If you want more fine control over the page title, you can always use a label specifying the coordinates as screen. Just add this before the last plot and you're all set. (If you add it before the first plot, the same label may be drawn a few times which is probably not what you want.)

You can write the supersript as X^2, and the subscript is Y_3. To make several letters super- / sub-script, you need brace like Z_{64}. To use super and subscripts at the same time, try Z@^2_{64}.

Attractive plots « Gnuplotting

august 2015 by aries1988

As you surely have noticed I don’t use the default colors and line styles from Gnuplot, but define them myself. The simple reason is that the default colors are not optimized to be very pleasant, but are simply primary colors. I just stumbled over an blog entry of Brighten Godfrey, which deals with some thoughts on beautiful plots.

Key

april 2015 by aries1988

The set key autotitle columnheader option is available if gnuplot was built with -enable-datastrings. This command causes the first entry in each column of plotted data to be interpreted as a text string and used as a title for the corresponding plot. If the quantity being plotted is a function of data from several columns, gnuplot may be confused as to which column to draw the title from. In this case it is necessary to specify the column explicitly in the plot command, e.g. plot "datafile" using (($2+$3)/$4) title 3 with lines.

february 2015 by aries1988

With contours you must be careful with the format of the data files. Isolines (say, x-bins) must be separated by a blank line! If there are two blank lines, gnuplot thinks that a new data set follows.

Setting front will draw the rectangle in front of all plot elements, but behind any labels that are also marked front. Setting back will place the rectangle behind all plot curves and labels. Setting behind will place the rectangle behind everything including the axes and back rectangles, and can be used to provide a colored background for the entire graph or page.

Gnuplot: An Interactive Plotting Program

november 2013 by aries1988

Here are briefly some useful hotkeys. Hit 'h' in the interactive interval for help. Hit 'm' to switch mousing on/off. Hit 'g' for grid, 'l' for log and 'e' for replot. Hit 'r' for ruler to measure peak distances (linear scale) or peak ratios (log scale), and '5' for polar coordinates inside a map. Zoom by mouse (MB3), and move in the zoom history by 'p', 'u', 'n'; hit 'a' for autoscale. Use other mouse buttons to put current mouse coordinates to clipboard (double click of MB1), add temporarily or permanently labels to the plot (middle mouse button MB2). Rotate a 3D surface by mouse. Hit spacebar to switch to the gnuplot command window.
