I want to plot some stockpile data.
The data is located in a csv-file and I already got an almost accurate plot, so reading from file isn\'t the problem.
Unfortunately you did not show any data from you file, but I guess you are using commas as decimal separators. In that case you need to set the right decimal sign for reading the input. You can use e.g.
set decimalsign locale
or use an explicit locale (this must be installed)
set decimalsign locale "de_DE.UTF-8"
Note, that setting an explicit character with set decimalsign ','
does not work because it usually affects only the output format of e.g. tics, but not the input behaviour.
