Details:
I am using Octave 4.0.0-rc3 from ftp://alpha.gnu.org/gnu/octave/ under Windows
7 64bit.
I love the new Qt graphics toolkit because it is fast and the onscreen figures
look nice. However, printing Qt figures to PNG, PDF and SVG files produces
strange results.
The attached script plotTestQt.m creates 3 rather simple figures and saves
them to PNG, PDF and SVG. The resulting files are attached, as well as
screenshots of the figure windows. The latter look all fine, even the Omega is
printed correctly (With the exception of figure 3, where the Unicode char for
Omega is used in the ylabel command).
However, all of the files have issues:
* Figure 1 has no bottom axis. The Greek Omega appears as "Omega" in the PDF
and PNG file and as "Omega" in the SVG.
* Figure 2 consists only of axes labels and tick labels in all three formats.
Axes, tick marks and curves are completely missing. The Greek Omega appears as
"Omega" in the PDF and PNG file and as "Omega" in the SVG.
* Figure 3 has nice axes and labels, but the curve is totally screwed: It is
intersected many times and has a lot of straight lines connecting the first
point to points on the curve. The Greek Omega is a strange symbol in the PDF
and PNG file and displayed correctly (!) in the SVG file.
