Origin Ver. and Service Release (Select Help-->About Origin): Operating System: Respected Sir, Here data in x and y axis. out put graph is in scattered linearly increases or decreases. i want to plot a slope of this graph. with regards x axis y axis 0.002221827 0.971 0.00254065 1.211 0.002964544 1.383 0.003006524 1.739 0.003018595 1.349 0.00282454 1.072 0.002573135 0.826 0.00225779 0.79 0.001865435 0.634 0.001497645 0.468 0.00118058 0.317
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.
