Description Roberto Peron 2011-05-04 11:09:33 UTC 
Version:           2.0.3
OS:                Linux

When doing a plot, the "Show point" and "Bargraph" options in the "Appearance" part of "Edit Curve" are not effective (i.e., the plot is not drawn) unless the "Show lines" option is selected at the same time.

Reproducible: Always

Steps to Reproduce:
Import a two-column data file and plot Column1 vs Column 2.

Actual Results:  
Selecting "Show point" or "Bargraph" as Appearance options, the plot is not drawn.

Expected Results:  
The plot being drawn.

OS: Linux, Ubuntu 11.04

Comment 1 Nicolas Brisset 2011-05-04 11:24:05 UTC 
Could you attach a small test case? I have just tried it here, and it seems to work. 
However, as far as I know, the point density option is not honored when lines are not shown (i.e. all points are plotted if you don't plot lines, regardless of what the greyed-out point density combobox indicates). This is a feature, as plotting only some points does not make real sense if there is no line going through all points.
Comment 2 Roberto Peron 2011-05-04 16:25:05 UTC 
Bug closed as "INVALID". The problem was raised due to a not proper interpretation the way Kst handles the comment indicators. Contrary to my assumptions, the data start line must be explicitly indicated in the configure dialog.
