           Summary: invisible curves when width != 0 or type != solid
           Product: kst
           Version: unspecified
          Platform: unspecified
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR
         Component: general

Version:           1.1.0_devel (using KDE 3.2 BRANCH >= 20040204, Mandrake Linux Cooker i586 - Cooker)
Compiler:          gcc version 3.3.2 (Mandrake Linux 10.0 3.3.2-6mdk)
OS:                Linux (i686) release 2.6.3-7mdk

When you draw curves with a width > 0 or a type different from the default solid line they are not always visible !

To reproduce:
1. Create a text file containing 50 lines with a '0' in each
2. Plot the 1st column against INDEX with the data wizard: it works
3. Edit curve attributes (contextual menu) and set width to 1
4. Notice the curve has disappeared. If you zoom in with the mouse, chances are you'll see it, but not with key accelerators (Shift+Down). Intriguing, isn't it ? 

Notes:
- it is apparently not linked with grid lines
- in some cases where values are not steady, parts of the curve are also missing. It is hopefully all the same bug. To check, use the data file I'll append to the bug report (width set to 1 gives a strange curve).
