How to create an intensity waveform graph cluster with t_0 and dt ?

Question

Hi all,
I would like to know whether it is possible to create an intensity waveform like you can do with a 1-d waveform (with "build waveform") so that you get a cluster with the waveform array, the t_0, the dtand the attributes. 
If not I would like to know the following:  I use references to cluster typedefs to update my controls and indicaters on the front panel. Now if I use a property node for the intensity graph to set the offset and multiplier on the x-scale, the x-scale on the graphs on the sub-VI work perfectly, however not on the real front panel, probably since these get updated through a reference. Does anyone have a clue how to fix this?
Regards, Pieter

Answer 1

You are only writing the "value" of the type definition via the property node. This does not include properties such as offset and multiplier.
On a sidenote, you are using way too much code for most operations.  
For example, the to-I32 can be placed on the cluster, so only one instance is needed.
Also property nodes are resizeable, so only one instance is needed.
There are also Rube Goldberg constructs, such as ">0  *AND* TRUE", which is the same as a simple ">0"
Overall, you are really fragmenting memory by constantly building and then resizing arrays to keep them at a max size of 2880. This can cause performance problems due to the constant need of reallocations. It might be better to use fixed size arrays and do things "in place".
