neuro,
I suspect plot() expects an array to be plotted whereas bc is a single
value.
Terry,
Initializing the array with C sounded like a good idea but it does not
work. Try this:
TestArray = C;
for(i = 0; i < BarCount; i++)
{
"The Value of TestArray[" + NumToStr(i) + "] is " +
NumToStr(TestArray[i]);
}
This code prints not a single thing on my computer.
