![]() ![]() The example will limit the x-range to because the last N=3 y-values are y<=0. When you plot the data, you simply limit it via every ::n0::n1. of arbitrary input size, and of both real and complex data (as well as of. else if y0 and n1 contains the line index when y was N-times Just to illustrate, you can also limit the data to an x-range where y>0 and including the first sequence of N values y0 and N values y0 & n0!=n0 ? n0=$0 : $20 & n0!=n0 ? n0=$0 : $20 and n0 is NaN (see gnuplot: How to compare to NaN?) then set n0 to the current line index $0 which will be the first time y>0. $Data 0 ? $1 : NaN):2 w lp pt 7 lc "red" notitle Using the ternary operator (check help ternary) the x-values will be set to NaN if y0 Result: Īctually, it was a bit of a xy-problem: You asked for putting data into an array, but the actual goal was to limit the xrange to the range where y>0. Stats FILE u 0 nooutput # get number of rows Script: (requires gnuplot>=5.2.0) # read data from file reversed into array ![]() The following script reads a column of a data file reversed into an array. This sentence makes me think that maybe there is more behind which you don't show and which can maybe solved also without arrays. To generate a PNG image with a width of 1063 pixels (90mm at 300dpi) without changing the look of the figure, set it up as follows, scale 1063.0/420.0 set terminal pngcairo size 420scale,768scale fontscale scale linewidth scale. Now I am trying to set the xrange that the upper limit is set where the data in the second column finally approaches zero. I will assume that you have already created a figure that is just the right size of 420x768. From your current question title and code snippet I assume you want to read data reversed into an array.
