LabVIEW
Waveform graph bug found while displaying X scale (screenshot)
Hi everyone... this is my first post here, however I think I have found a pretty large bug! Let me give a little background infomormation on what I am trying to do). My VI takes an arbitrary amount of databuffers that have been recorded at various sample rates and for differing lengths of time and graphs the data on a single waveform graph. With the different sample rates, sample start/stop times, and sample durations I have been making sure that each plot is correctly bundled with an appropriate X0 and deltaX, and also correlated with the correct Y scale. All of the "heavy lifting" of associating plots with the correct Y-scales and labels is done with property nodes (ActPlot, ActYScl, YScale.Offset, YScale.Multiplier, YScale.NameLbl.Text, etc). Furthermore, I manually set the min/max on both Y Scales, as well as the min/max on the X scale.
Now, the problem: It seems that somewhere in the process of changing all of these properties, that LabView got confused on what/how much it should actually be displaying. Here is the image, problem areas in the red box.
I have tried changing __ALL__ options on the X-scale, and even removing the extra Y-scale (it seems to be not displaying the section about the width of the 2nd Y Scale Label). Each time the VI runs, I manually set the min. to -3E-6 and the make to 1.1E-5
Can anyone figure out what the heck is going on that would cause Labview to not display all of the data within the min/max range, or to display whitespace beyond the (in this case) maximum?
Any help appreciated,

Ok, here are two images. The first is the data I am graphing completely unaltered in a cookie-cutter, all-default waveform graph. The second graph is the modified graph from my program.
VI is attached, but it will be missing lots of SubVIs... however, most of the important graph stuff will be apparent.

I've see that before...
Do the following:
(1) Right-click on the graph ---> "advanced ... reset scale layout"?
(2) Right-click on the Volts scale ---> "swap sides"
(3) repeat for all graphs with bad scales.
That should fix it.
