Alan,
Thanks for the quick response. You are correct, this was a rather
convoluted piecemeal hack of several examples from both wxwidgets and
plplot.
Attached is a simplified version. There is one, and only on, plot
function, and a very simple widgets GUI with no buttons or menus.
The issue is present, i.e. no tick mark values and no labels. I did not
add any external frames, rather than show a difference I opted to show
one thing in this example.
The only real difference is that I am using a wxPanel to make the plot
in the splitter window.
I am fairly new to both PLplot and wxWidgets so I may be using these
functions incorrectly (it is not my intent to unnecessarily spin people
up for help but I have tried and am clearly missing something). Viable
hypotheses are (1) I'm instantiating the Panel incorrectly, (2) invoking
the plot incorrectly, (3) that plots and panels don't work like plots
and frames do (and I'm missing some data), (4) there is a size issue and
the text I expect to see is outside the limits of the Panel.
As I stated before, in a more complex code base this issue goes away if
I "re-plot" the same plot in the same window via an external button
push. Would it help if the plot function was "owned" by the myApp?

P.S. I noticed just after (natch) I sent off my previous post that you
had included source code in your post, but it is hard for me to
evaluate whether you have simplified that example as much as possible.
So here is what I would like you to do instead. Please give us the
simplest possible patch for examples/c++/wxPLplotDemo.cpp that
demonstrates the issue. Such a patch clearly demonstrates the minimal
changes required to show the issue. It also should allow our current
build and test system to build and test your (slight) modification of
examples/c++/wxPLplotDemo.cpp, and that would be a great convenience
for us when we are attempting to replicate the issue on our various
platforms.
