The script main.py follows. It defines all functions executed by the callbacks in the project wizard CustomLayoutWizard. These functions reference the defined layouts using GetComponent().

def onrefreshTabularDataSample(step):
    comp = step.UserInterface.GetComponent("TabularData")
    table = step.Properties["Table"]
    comp.SetPropertyTable(table)

def onrefreshChartSample(step):
    table = step.PreviousStep.Properties["Table"]
    tableValue = table.Value
    rowCount = table.RowCount

    x = []
    y = []
    for rowIndex in range(0, rowCount):
        x.append(tableValue["Table/Time"][rowIndex].Value.Value)
        y.append(tableValue["Table/Pressure"][rowIndex].Value.Value)

    comp = step.UserInterface.GetComponent("Chart")
    comp.Plot(x, y)

def onresetTabularDataSample(step):
    #nothing to do
    pass
