[Gnuplot-info] Urgent help! From: olleorama - 2007-05-24 09:45 ```Hi there! Urgent problem! I have datavalues (y) in a multicolumn file 'xxx.yyy' column 2, and the x-values in column 3. I want to make profiles with the y-axis negative, i.e. y=-y, but my main problem is how to assign the values from column 3 as the x values. If I use plot 'xxx.yyy' using 3,2 I only get the data values plotted against a dummy vector and a solid line on y=2, which isn't what I want. And if I use "plot 'xxx.yyy' using 3, using 2" or "plot 'xxx.yyy' using 3, 'xxx,yyy' using 2" I get either errors or multiplot figures, which isn't what I want. So how to assign a column to the x-values, and how to make the y-axis negative. Anybody? I must be really thick but I can't get this working here. And the most annoying thing is that I did the exact same thing last week! -- View this message in context: http://www.nabble.com/Urgent-help%21-tf3809056.html#a10780544 Sent from the Gnuplot - User mailing list archive at Nabble.com. ```

Anybody? I don't know if I'm understanding exactly what you want to do, but to plot = a column as -y, then: plot 'xxx.yyy' using 3:(-\$2) again, see help using and help plot. Bye!

Totally forgot about the '\$x' construct.
