Here is the dataset - the testdata.gdt. Imported from OECD, than from OpenOffice.
The file TestPlot1.png shows two plots.
First, there is a plot of an output gap. Cursor was placed to the highest point at the
peak before 1990. The position identified in the left-low corner of the plot shows it is
in the second quarter of 1989 although the data show it was in the fourth quarter of
1989.
Second, there is XY scatter plot cpiexp vs. gap with label at the observation at the
1Q1984. The true value of the gap at this point is the same as on the plot according to
the labels on the x axis (-4), however the cursor coordinates report -3.6 for the value of
the output gap at the same observation.
This is a bit tricky - I don't know neither the cause of the problem nor how to solve
it. From time to time I would like to see, when some peak occurred and like this I have to
import selected time series back to OpenOffice or to have a look at the values
explicitly.
There's no problem like this in Windows on the same machine.

Dear gretl-friends,
I think I've found a bug, but I'm not sure, so please can anybody check it?
I'm using gretl on Kubuntu (currently 9:10), Gretl version 1.8.1 and 1.8.6, gnuplot
4.2.6-1 and plots are shifted to the right.
Using a "time series plot" the points for let's say 1985 are placed as being
in 1986, on XY scatterplot everything is shifted again to the right with respect to the
values of variable on the X axis.
I've found the same thing on gnuplot and gretl in kubuntu repositories, that is for
the gretl 1.8.1 version and associated gnuplot version.
If this is not a bug and it can be fixed by some command to gnuplot or some change in
gretl settings, I will be very grateful for any advice.
With best regards,
Jaromir Baxa

Could you give a simple test case, using one of the supplied
datasets, and post a PNG of the graph? Thanks.

The read-back of the cursor position is only a rough approximation
unless you're using gnuplot 4.3 or higher. Perhaps we should not
do this at all unless we have a new enough gnuplot.

No, there wouldn't be, since the gretl package for Windows
includes gnuplot 4.5.
