| Subject | placing expressions in "using" fails |
| From | Fritz Sonnichsen <sonnichs@gmail.com> |
I am trying to do some elementary data manipulation before plotting a curve, such as "divide all by 2". The documentation vaguely alludes to this in the form: plot '$file1' using 1:($17/2) w l t However when I use this construct I get and "invalid expression" condition and the field "$17" appears to be empty (it is not). The gnuplot doc I am referring to is: http://gnuplot.sourceforge.net/docs_4.2/node133.html any ideas appreciated thanks! fritz
