I would like two know how I could generate this graph in the HP prime. Given data points(no functions) for the equilibirum curve (red curve). My problem is I have tried to use the stats2var app but i can only plot 1 curve. how can i plot two and be able to read the axsis so i can determine the points where the red and black curve meet and the number of steps between the curves. it is important that i can read the axsis because in order to find the black curve i must first find the (x,y) where the red and black curve intercept.
in my problem i am given plenty of data points for the red curve but only (x1,y1) and (y2) for the black curve. so i need the x2 where the curves intercept (top right).
below I have posted a picture of what i am tring to generate on the hp prime. I think the squence app has a similar picture but i am not sure if i can use squence app without having the function.
the easiest thinkg for me to do is to use something like excel scatter plot but i am not sure if hp prime spread sheets is that robust.
any help will be apperciated please include pictures or steps i can take to do this. if there is no built in app that can do this can this be programed easily?
