use external data for x axis of a graph

[F.Willems]

Hi,

I am looking for a way to use external values (from a tdms) as x axis values in a graph.

Just like you do in excel where you select a column to use as the x axis values.

The first channel of the tdms holds the values of a counter. (xx.yy secs)

I cannot find a way to use these values as x axis reference.

Thanks in advance.

Hi F.,

why do you use a SplitSignals Express function to index elements on a waveform array? (Get rid of ExpressVIs and DDT as much as possible…)

On your question: get the Y component of your waveforms and build a XY graph from them!

Like this:

You actually want to use an XY Graph.  You use a Bundle to create a cluster.  The first item is an array of the X values and the second item is an array of the Y values.  This cluster then gets wired up to the XY Graph's terminal.
