Crash with -c flag and command line arguments

I can confirm that this is happening on Windows 10 with gnuplot 5.4.2. Here's a diff of test_key-title_fig.tex: --- no-key-title/test_key-title_fig.tex 2021-09-02 10:14:07.804128700 -0400 +++ key-title/test_key-title_fig.tex 2021-09-02 10:14:52.742447300 -0400 @@ -165,8 +165,9 @@ \csname LTb\endcsname%% \put(209,2541){\rotatebox{-270}{\makebox(0,0){\strut{}test}}}% \put(3940,154){\makebox(0,0){\strut{}test}}% + \put(5979,1073746140){\makebox(0,0){\strut{}test}}% \csname LTb\endcsname%% - \put(5816,4206){\makebox(0,0)[r]{\strut{}test}}%...

You could use the time function before and after the fit. Something like this: t1 = time(0.0) fit f(x) 'data.txt' via a t2 = time(0.0) print t2 - t1

Here is a minimal working example: set lmargin 40 set xrange[1e5:1e10] set yrange [-50:0] set logscale x set xtics add (1e2, 1e4) set grid plot -40 We see that there is a vertical dashed line where x = 1e2 and x = 1e4 would be located if the x-axis were extended. Every terminal I've tried does the same: qt, wxt, png, pngcairo, pdfcairo. Is this a bug or a feature?

You can tell gnuplot to treat undefined data, such as 1/0, as missing data. Missing data is not plotted and does not leave a gap. See help missing. set datafile missing NaN plot "-" using 1:(($3==3)?$2:1/0) with linespoints 1 1 3 2 2 3 3 3 4 # This line has bad data in it that I want to skip 4 4 3 5 5 3 e

This can be done with bins. The width of each bin is 1 day or 60*60*24 seconds. set style data lines set xdata time set timefmt "%Y-%m-%d" set xrange ["2020-05-02":"2020-05-18"] set yrange [0:5] plot 'sample2.txt' using 1:2 bins binwidth=60*60*24

Fair enough. I agree that this is a really small bug.

When you print a single character with "%1c", that character occupies the full width (==1). I agree with this if a prefix is printed. For example, the output of gprintf('%1c',1e4') is k, which is one character. That's correct. But with gprintf('%1c', 1) there is no prefix to print. The output should still be one character wide (one space) but currently the output is an empty string. It's a bit hard to discuss invisible characters. I think it might be clearer with the script below. The comments show...
