Hi all
I have a relatively simple Qt program which utilises the PlPlot Qt widget
(QtExtWidget). QtExtWidget is a component of the main application window
and as such is constructed during program startup, prior to the calling of
QApplication::exec() and before any GUI elements have been made
Hi Hez
Speaking as someone who regularly prepares plots for scientific publication,
having a custom labelling function for the axis labels would be great.
Currently the bulk of my work isn't done using plplot but rather with a
custom plotting framework I wrote around plotutils, but as
Hi
extXdrawable_demo.c was donated a year ago by Jonathan Woithe. He kindly
agreed recently to relicense this code to LGPL to be consistent with the
rest of our licensing. ./extXdrawable_demo builds and works without issues,
but a plot consisting of just 3 points is less than exciting so I
The patch below (against svn rev 8364) addresses this by moving the
definition of PLXcairoDrawableInfo from drivers/cairo.c into
include/plplot.h. It is still protected by the PLD_xcairo so at least in
theory its presence should not cause any trouble when plplot is compiled on

Hi Hazen: For what I use the memcairo driver for, clearing the memory not
not the behavior I want. I want to pass in some memory already containing
an image and then plot a graph on top of it. To first generate the image
and then have plplot clear it would be disappointing, to

Currently the PLXcairoDrawableInfo structure used to pass an external X
drawable in to the xcairo driver is private to cairo.h. This means that
anyone using this feature must define their own structure to do this which
opens up the possibility that they could get the field ordering wrong. It
Hi Hazen
I am working on an application which requires plots to be displayed
within the context of the program's windows. In practice this means
that I needed plplot to have the ability to plot to a supplied X
Drawable rather than to an X window which plplot creates and manages
itself.

I suspect there might be some issue going on between the different versions
of plplot on your system. It would be nice to pinpoint the exact cause.
Hazen and Hez may be comparing apples and oranges.
I agree. The circumstances on the systems are different and I suspect that

it does then it might be a good idea to try and keep the

thanks again for your comments and for the patches. As usual I already
worked on a fix and in fact made nearly the identical changes to the
code as you suggested (commited to svn just now). About the merging

Hi guys
I have a question regarding the calling of plsetopts() multiple times
to set device options without any intervening plend() call. From a
brief look at the plplot source code it seems that doing this may cause a
memory leak.
Calling plsetopts() ends up at c_plparseopts() via c_plsetopt()
