Thanks, CJ. This is good stuff.

In the simplest terms, here is what I need to do: I have a bar graph module with specific settings for the lower limit and upper limit properties. While the program is running, I need to find a way to change the lower and upper limits on the bar graph when the signal from a digital input goes to zero (for example). Basically, I want to dynamically change the scaling of the bar graph while the program is running. Is this possible with some sort of action module? Although I'm new to DasyLab, I know VB and C++ in case this solution might require some programming. Thanks in advance, Andy
