Hi group, I was not entirely sure what to put in the subject line...
I did a very simple physics experiment involving two strings, two weights and one pulley. I'll spare you the details, but by varying one of the two masses, I measured the angle one of the strings made with the vertical. I got these results: # m2 alpha 0 0 10 12 20 23 30 32 15 18 25 27 12 14 22 24 27 29 17 20 where the first column is the mass of the second weight and alpha is the angle, in which I made an error of ±1 degree. So far, so good. Now, I want to plot in gnuplot the following: m2 along the x-axis, but the tangent of alpha with errorbars along the y-axis. So, I have to process this data somewhat further to obtain a second data file with three columns: m2, tan alpha-low, tan alpha-high. Of course, I could use gnumeric or something like that, but I'm wondering if there are command-line tools out there that could do the job. Or should I use a scripting language? perl? awk? bc? Efficiency is not the problem here, ease of use is. Thanks in advance, David -- Hi! I'm a .signature virus.
