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;
As i figured out meanwhile the "plot:Add(..)" statement crashes silently. The next statement "plotX = plotX + 1;" does not become executed, hence the plot.redraw statement will not be executed too.
