Hi all.
I use Lua5.3 (TDM-GCC_64) on Windows10 together with iup,cd,im
(precompiled DLLs from sourceforge). So far it works great.
I want to plot new measured values every second into a iup.plot inside
my dialog. (see attached screenshot).
During program initialization i create the plot:
plot = iup.plot{
marginbottom = 20,
};
plot:Begin(0);
plot:End();
plotX =1;
later comes the dialog.show().
i use a iup.timer interrupt to read new values every second and try to
display them:
local s = comPort:read(64, 600);
if s ~= "" then
messages.append = s;
plot:Add(plotX, tonumber(s:match("%d+")));
plotX = plotX + 1;
plot.redraw = "CURRENT";
end;
But it does not work like expected: The plot window stays empty.
I can see the plot context menu by right clicking the plot area.
I can drag and resize the main dialog without effecting the plot content.
Any help?
Ulrich.
