I have set up a historical display, based on the “Click to Graph” example.
I am displaying flow information, which is stored as meters cubed/hour (m3/hr) in the historical database. This works perfectly.
I would like to be able to switch between displaying the data as m3/hr and litres/second (l/s).
To convert from one to the other is a simple matter of multiplying or dividing by 3.6.
How can I achieve this automatically when the user makes a radio button selection on the Click to Graph screen?
Can it be done with calculation pens?
Is there any access to the data that is being used to plot the Easy Chart, so that I could simply multiply it by 3.6?
