           Summary: No curve plotted at all when one data file is missing
           Product: kst
           Version: 2.0.3
          Platform: MS Windows
        OS/Version: MS Windows
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR
         Component: general
        AssignedTo: kst at kde.org
        ReportedBy: gregoire.verlut at eurocopter.com


Version:           2.0.3
OS:                MS Windows

I prepared a kst file, using several existing data files.
I then corrected the "file" entry in the kst file to be sure that all
references are relative (ie file and fileRelative are in fact relative
reference)

I copied the kst file to another directory, where some of the data files used
by the kst are not present.

When I open the kst file in the new location, no curve is plotted at all.
The data manager shows that the vectors for the non-existing files are filled
with 3 data. It's 3 times NaN.
The curves are also created with 3 data, but nothing is plotted, not even the
curves corresponding to the existing files

Reproducible: Always



Expected Results:  
I would expect kst to plot at least the existing files, like when a vector
contains NAN.

Perhaps a warning by loading the kst file that some files where not found,
either via a pop-up window or in the status bar.

OS: Windows 32-Bit
