invalid property value waveform chart

[rickford66]

I'm using LV7.0 and have an issue accessing a waveform chart using a property node.  I have a number of property nodes for the same waveform chart that I am addressing at the "same time".  I'm using a reference to the chart into generic property nodes.  I believe I have 7 available plots on the chart, but as I address them, 0 through 6, I get an invalid property value error (arg 1) on 6.  It looks like it doesn't like me setting the ActYScl to 6.  When I pull up the chart properties, it shows that I have 7 plots available.  Is there some obscure setting somewhere that limits the number of plots?... or is there anything that is well known that would cause this error.  The entire program is quite complex, and would take a while to strip it down for posting, so I wanted to know if there was anything off hand that can cause this.  I've attached a pic of the trouble spot.

Thanks.

You might have 7 plots, but do you have 7 Y-scales?  If you have 2 or more plots assigned to the same given Y-scale, then you probably don't have as many Y-scales as you have plots.

There is no correlation between the number of plots and the number of Y-scales.  Even the order of plots vs. Y-scales could be different.

Ha, I knew it was something simple.  Thanks!
