# make two plots in hp prime and count steps

HP Recommended
Hp prime
Microsoft Windows 10 (32-bit)

Hi,

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?

Do I understand you well that when 4 points on the red graph would have coordinates:

(1,3) (3,6) (6,7) (8,7.5)

the coresponding points on the black graph would have coordinates:

(3,3) (6,6) (8,7)  ??

In Statistics 2Var this would look like:

What option did you select in Stats 2Var to get the lines plotted between the scatter points?

In Plot Settings (Shift-Plot), second page, I checked the Connect box.

Another thing I did was turning off 'Trace'  in the menu of Plot View, because I wanted to be able to tap any position on the screen and see its coordinates.

In order to actually see them next tap the 'Menu'  button on the screen.
