How to use JSL to calculate a curve whether the lines of each adjacent high point of multiple different peaks are the same line?

[#1]

Hello, everyone!Is there any existing module or function for this function?
How can this be done quickly?

Thanks!

Can you show a plot of the data and explain further what you have and what you want using references to the plot? I have no idea what you are trying to do. "Calculate a curve?" "Lines of each adjacent high point?"

Thanks Experts!

For example, in this curve, the slope of the line is calculated with the right-most stage high point followed by the stage high point on its left. When the difference between these slopes is within a certain range,

If necessary, the one with the highest slope can be ignored
