Waveform chart - What is maximum number of digital displays ?

[Doctor John]

I'm writing a LV app that needs to show a maximum of ten plots and also show the current digital values for the data. 

I'm using the waveform chart indicator for the plots.  I would like to use the digital display attribute built into the waveform chart.  I can get ten plots however I can only get nine indicators to display.

Is there a built in limit for the number of digital diplays?

Thanks

John

Further to my last post, I subsequently discovered that the waveform chart seems to be able to plot only nine plots max.  Even though the plot legend will display ten or more plot names.

A ten or more element data array when bundled and wired to the waveform chart seems to be truncated to nine bundle elements.

Is this a documented bug with the waveform chart?

Sincerely,

Charts can definitely display more than 9 traces. Somethig is wrong. Could you attach your code so we can see how you make the cluster?

Could it be that you are converting an array to a cluster? Here the default cluster output size has 9 cluster elements and you would need ot right-click to change this. As an example, attached is a VI (LabVIEW 7.1) that shows 20 plots on a chart and also shows 20 digital displays.

I figured this one out late last night. 

As it turn out, I was initializing the history buffer at the startup to the vi using an attribute node.  Somehow this initializing bundle got set to nine elements inadvertently and as a result it was setting the maximum number of plots that could be displayed.  By adding another bundle element, I was able to get to the ten plots that I needed.

Sorry for crying wolf, although it did take 12 hours to stumble across the root cause.  The number of plot names in the plot legend doesn't seem to be tied to the number of actual plots so as a result this led me down the wrong path to resolving the issue.
