Hello,
My VI is complex so I'm going to explain how it works. I get some digital signals from a serial port, each signal is converted to a waveform, there are nine signals that have differents time bases. Each signal have a dedicated scope chart, those nine charts are on the first page of a tab. The second page of the tab contains only controls (like string control, digital, but nothing special on it...). The x axe of the scope charts is time (24 hour HH:MM:SS with 3 digits) this time is generated by my program, not by LabView itself.
The problem :
When you run the program, the t0 form every scope charts is the same ( for exemple 10:48:23,324 ) and the signals appears correctly, I can minimize the windows and maximize it without any problem. When I
decide to look at the second page of the tab to change or add some values (no relation with the scope charts), and then I come back to the first page of this tab some or every scope charts are empty.
The t0 written on the scope charts is in the future, and the current waveforms are correct (not empty, and the t0 is real (current time)).
To change this problem I can :
1. clear the chart !
2. or wait for the real time t0 becoming the t0 written in the scope charts ??!!
Remarks:
this thing happens when I'm on the second page of the tab and a scope charts arrives at is end (rigth border of the scope). this problem never appear on a scope chart if is property XScale.Maximum is less than 20 (2 secondes).
Is it clearer ?
Thank you for your answer !
Current version of LabView is 6.1 under windows 2000 pro Pentium III 866 - 256 Mo.
