Wow a clue, Acording to your status bar the StampPlot it received an HISD or History enabled which was not part of the code you posted. Post your current code so I (or someone) can help you debug.
Attached is the code posted which I·tested·- see if it works for you. If not than it may be a circuit design issue.
Is this your circuit?· This is from the Whats a Microprocesor PDF.

Hi..this is how my graph looks like and the values are actually
3
3
3
3
3
3
then it raises up to 40s when I block the light..
40s????? is the "s" really there? That would confuse stampplot. The plot data should be just number strings. Such a low number too - you gotta post the circuit.
BTW
Assuming your using a BS2 and that your using the VT935G Photoresistor that Parralax sells,and given that a bright sunny day yields around 500 ohms and a covered photocell yields 46k, and your using a .01 microfarad cap.
I would assume your just passing your hand over it. Those rctime reading - would be be plausible under those conditions.
40/.01/635= 6.3k
If your actually covering the cell and making it very dark then maybe your using a .001 microfarad cap.

Does that mean you see the data on the status line of the StampPlot program? (Make sure the basic stamp editor is not running while testing - it may hog the comm port).·
I'm a bit stumped because everything I do works on this side. Check what COM port stampplot is on then I would suggest trying Stephen's suggestion and uninstalling and installing Stamplot.

That is my code...and no the "s" are not there..lol...can you post your code this way? or how do I take the code from your att..?
And yes to the circuit design and capacitor value
1. Send made up data to stamp plot like
for i = 1 to 50
debug DEC i
next
2. Remove, download (again) and reinstall stamp plot.

1. get rid of the plot commands your status line points to an error with a HISD command. Like this:
' {$STAMP BS2} ' {$PBASIC 2.5} time VAR Word DO HIGH 2 PAUSE 100 RCTIME 2, 1, time DEBUG DEC time, CR LOOP·2. When you run this code you should see your data on the status line Here:
·
This should happen whether it plots or not and will indicate if your comm is working.

using this code

on the stats line, while using the plt i posted?

BTW Open that plt file by Double Clicking on it, not from the program.
