Controllogix Real To Log(real) or ln(real)

I am trying to convert a floating Point value that ranges from 0.0001 - 100000.00 to be displyed on a graph where I would like the Y Scale to be Log (not linear scale), and x scale = Time. Do I use the Log function or the Natural log function for the Real number conversion?

Thanks

Only you can answer that....

But I suspect you want the standard log, the natural log (to base "e") is not widely used - but i guess that will start a flood of responses where it is used, lol
