Hi,

If you want the output graph in monotone increasing or decreasing order, you need to sort your data first (right click on X column and select "Sort Worksheet: Ascending"). To get the slop of the curve, please use "Analysis: Mathematics: Differentiate" and calculate the 1st-order derivative.

Thanks,
Amanda
