Display Random Text with Parameters
I am trying to create display that has a patient’s vital statistics like heart rate, temperature, blood pressure, etc. And I want to have these values refresh every two seconds and increase/decrease over time.
For example I want the heart rate to stay within a range of 210-215 and change every two seconds. I am using the random number generator that allows for a range of values. The first problem I am running into is getting it to have no decimal points. The second problem is integrating the holdFrame expression that will allow it to only refresh every 60 frames. I am just diving into expressions and any help will be awesome. -

The easiest way to drop the decimals would be to use
Math.round(x), which returns the nearest integer, orMath.floor(x), which returns the integer immediately below the current value, orMath.ceil(x), which returns the integer immediately above the current value.The easiest way to delay the update of the text is to delay the update of the expression with:
posterizeTime(x);Where x is the number of times per second to update the returned value of the expression. If you wanted the expression to update every 2 seconds you would use:
posterizeTime(.5);Darby Edelen
