How to programmactically change XY Graph range

[dylancor]

Hello,

I am trying to update my XY Graphs x axis range from the front panel. From the front panel I am using the 2 user inputs Span and Centre Frequency to determine the x axis range. I have created a property node -> x axis -> range -> maximum but this doesnt allow me to then use the user inputs from the front panel to set the max.  

Thanks for your help.

I have attached my VI.

You are currently reading the properties. Right click the property node and select "change to write"

You need to set the property node to "Write".

(I would do it in a parallel loop using an event structure. You only need to set a property whenevern it changes, and not with every iteration of the loop)
