I have a very simple plot script:
plot "test.csv" using 1:2 "%lf;%lf"
It is used to plot file of the form:
I cannot use the general data seperator as I have a more complex plot command with different types of input data. In version 4.4.4 this works fine.
I tested with 4.6.1 and the current CVS checkout, and both abort with the following message:
warning: Skipping data file with no valid points
x range is invalid
I searched around the sources and found, that the check for valid_format is not performed as the parser is currently at the "u" of using, not recognizing the format string at that point (src/datafile.c line 1399 and following). The documentation states that the above plot command is valid.
