This takes a variable such as temp(0), and uses the expected value (60-90 in this case) and maps it to another value, in this case 200 to 100. I used the existing graphing example, modified for a DS18B20.
I suppose in this case you could map 300 to 0, to fill the graph.
I want to thank the developers. This is the most fun with gadgets I've had since the Arduino.

Code: Select all
memclear
graphics 300,300
timer 1000, [doit]
[top]
x = 0
InMin=60 'expected low input
InMax=90 'expected high input
OutMax=100 'desired max output
OutMin=200 'desired min output
' in this case, 60 maps to 200 and 90 maps to 100.
