Waveform graph legend
Chad I assume that these 32 limit plots actually have data. Assuming you have at least 2 points to make the line (other plots may have more points if you are sending the data to the graph using a cluster) but you just don't want the legend shown, create the legend for all 48 plots by expanding it by dragging the corner of the legend. Then use the property node Legend/Plots Shown and set it to 16. You may have to do this after writing data to the 32 plots or at any point in your VI if you have saved the VI once after writing to all 48 plots but try just setting it to 16 first. R.

RE: Waveform graph legend
Chad We have in the past used a transparent plot overlaid on the base plot. This gives you independence between your data plot and the limits plot, easing some of these issues. Of course, it creates other issues, like synchronizing graph scales, etc. But for our case(a multi-trace chart), where we had thousands of points per trace, management of the chart appearance was a worthwhile tradeoff for the faster charting, etc. that resulted.

What are some ways to work around this? The legend or the plots defines what plot channels are available. So if you want to be able to change plot attributes you need to either make sure there is according data for that plot or the legend is expanded to show that channel. It is as simple as writing a single NaN value for each channel you want to be able to change plot attributes for.

Waveform graph legend
I have waveform graph of 48 plots. The first 16 plots are the actual data. The last 32 plots are the upper and lower limits for the first 16 plots. I have the legend visible and only expanded to for the actual data (first 16 plots). So there are only 16 plots in the legend. If the color one of the plots in the legend changes the color of the limits needs to change accordingly. I do this by using a property node (set active plot, plot color). But since legend is not expanded to include the limits an error 1077 Invalid property type is given. If all 48 plots are included in the legend I do not get the error. However I would prefer to not display all 48 plots in the legend. Has anyone else seen this? What are some ways to work around this?
