[Question] Graphing with a List
I want to make a graph like this:
Code: FOR k FROM 1 TO 500 STEP 2 DO To solve this I tried to make lists with values, then to copy to my program, But I don`t know how to copy the values in an easy way instead of formatting myself. Does someone has an easy solution for this? Code: L1:=MAKELIST(30+f1(k)*0.15,k,1,500,2);

It also works for local variables created in a program. Unless your data changes frequently, I think you have the fastest approach (i.e. generate the data outside of your program, and have your program simply graph the data). Would it be possible to share your formula for your functions? Perhaps there could be something in the functions that we could help optimize. Graph 3D  QPI  SolveSys

RE: [Question] Graphing with a List
Thanks for the fast reply.
The thing is I have the values in list L1, also the values doesn't change. But I wanted a list inside my program with all the 250 values of L1 without having to type then manually. I mean, I generated the values to L1 one time, then I get somehow these values and copy then to a variable in my program (L1 copied to a LOCAL listx1). Formating all these values one by one seems the wrong way to do it. Quote:Would it be possible to share your formula for your functions? Perhaps there could be something in the functions that we could help optimize. The code is below, and the functions sl_t() and sv_t() come from this post: Steam Table IAPWSIF97 Code: FOR k FROM 1 TO 368 STEP 3 DO Plotted graph

RE: [Question] Graphing with a List
I've managed to create the lists without having to evaluate the functions at plottime.
Solved.

RE: [Question] Graphing with a List
Hello,
This example is very useful about graphing a curve point by point using the graphic commands of the prime (arc_p or whatever). Is there a way to use the prime plotting features instead of building our own graph? I mean, if we have a set of points (list,matrix) which is the best way to plot them? Thanks Giancarlo

RE: [Question] Graphing with a List
Example:
You have L1:= MAKELIST (X,X,1,100,1); L2:= MAKELIST (X^3,X,1,100,1); L1 will act as x and L2 will act as y. Go to App > Statistics 2Var Go to Symbolic View Enter the L1 in place of C1 and L2 in place of C2. Then go to Plot View Go to Zoom and Autoscale. Done. PS: The lists get erased after plotting, and at some configurations they can generate strange values.

Hello,
In the meantime, put your data in C1/C2 and you won't have a problem. TW Although I work for HP, the views and opinions I post here are my own.
