array to graph

[6879]

Hi,

I have array which contain values for x and y axis. how to pass this value to generate graph. how to display x and y-axis coordinate and pass this value.

thanks.

If the x-values are not spaced equally, you need an xy graph.

Let's assume you have a 2D array with two rows or colums. Use "index array" to get the two slices as 1D arrays, then bundle them (or use "RE/IM to complex" to make a complex 1D array). Wire to a xy graph terminal.

See how far you get... (See also)

where do u define step size for x-axis and y-axis?

There is no step size.  Each element of the two arrays represent and X, Y pair.

If the x-values are spaced equally, you would use a plain waveform graph.

The linear relation connecting the array index of the y-array with the actual x-values is given by the offset and increment of the x-axis property. This can be set with a property node. You can also make a special cluster with three elements: two scalars (offset, increment) and a Y array. Wiring this clsuter to a wavform graph will also adjust the x-axis correctly. (of course you could also build a waveform).
