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) -- Márcio Paduan Donadio Engenheiro de Computação - Software de Operação das Linhas de Luz Laboratório Nacional de Luz Síncrotron – (LNLS) Centro Nacional de Pesquisa em Energia e Materiais (CNPEM) + 55 (19) 3512-3520 - [email protected] www.lnls.cnpem.br ------------------------------------------------------------------ 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, |
