You can use loc variables in X PV and Y PV parameters. Eg: loc://x and loc://y.
Inside the script you can do something like this:
from java.util import Arrays
from jarray import zeros
from java.lang import Double
x = zeros(NUM_OF_STEPS, Double)
y = zeros(NUM_OF_STEPS, Double)
for i in range (NUM_OF_STEPS):
x[i] = 0
y[i] = 0
# Do processing....
pvs[0].setValue(x)
pvs[1].setValue(y)

Hello
Is it possible to draw some data on an XY graph widget from a script/rule without using a PV? I mainly tried setting the property 'pv_value' but nothing appears on the graph. I'm
not sure if this is even possible or not. The thing is I will receive a waveform PV value and I want to do some processing on it then displaying the output on the XY graph.
Best Regards,
Abdalla.
