]]>I try to integrate these values.

The program does not figure out the right values, and also the area under these points does not correspond visually either.

I've tried to reinstall the program, but is there any settings I could make?

]]>I've used Graph for long time and I'm very pleased with the program.

But now it has occured a major problem when I plot the inverse of a function, the trapeze don't fit with the points!

Is there some settings I could change ?

Thanks in advance for your answer
