Description Jochen Garcke 2005-09-07 03:19:52 UTC

Version:           1.2.0_devel (using KDE KDE 3.3.2)
Installed from:    Debian stable Packages

If one prints black/white plots of color graphs (or sets the lines to dotted lines or dashed lines) the dots/dashes have the right distance on the screen but not in the printout. Same with the "save eps in vector format" option for saving.

The distances between dots/dashed seems to be fixed but should depend on the output device.

picture to show the unwanted behaviour. Two of the graphs are dashed/dotted but
in the picture this is not really visible.
Furthermore, I just realize that the cross in the legend is rather small...

I don't think there's any simple solution to this problem as we are using the Qt pen styles to get the desired line style. This seems to use fixed lengths for the various dots, dashes, and spaces. If anyone has a solution (other than drawing all the dots and dashes explicitly) please attach it to this bug report.

Comment 3 Andrew Walker 2005-10-21 23:54:51 UTC

For performance reasons we don't want to draw the line style ourselves and there is no ability to modify the line style beyond what is made available in Qt.
