bug in graph legend updates

[Albert Geven]

A simple way to get into problems we don't completely understand.

open the project

open the Main Vi

Open also the display vi " Sensors fglb with graph error.vi"

arrange the windows so that the "Sensors fglb with graph error.vi" is visible and the Main vi is in the left top corner and the error cluster is visible

now run the main vi

you may switch in the sensor display between raw data and temperatures and in any way I see in temperatures an error half of the time

when delivering no data to the graph and don't tell that this is a feature

So we decided this was due to the data yes or no available.

But when switching to show all data I still see the error appear.

Especially when the frontpanel of the sensor display is covered with a window (some window)

This last one bothers me most.

It get's even freakier, if you scroll the chart off-screen it will always error...

It has nothing to do with the tab.

I've gathered some statistics:

On the horizontal axis you see the index, the y-axis shows the number of erros/non-errors. In red the errors and with white squares the non-errors.

In the left-upper hand I had half of the plot visible, upper right the full plot visible, lower left none of the plot visible (scrolled off-screen)

Strange.
