Hi, can you post an example of your code? do you know the limits of the spectrum? what is the relationship between the index of the array being displayed and the start and stop frequency, because you should be able to either directly set the max and min limits, or if your array is 2D where the second dimension is frequency, you can extract an array subset from your start frequency to your end frequency and just display that subset: the graph should resize itself. Please give some more information, and if possible some sample code.

Good luck!

Without getting into details, you can set the min and max of the x axis of a xy graph programmatically by creating a property node for the graph.
