How to plot a graph by only using X and Y coordinates?

[fliptoback]

Sorry for all the many questions - I am learning to use Calcpad and am struggling a bit here and there.

I am trying to plot a graph and whilst I know I can do:

$Plot{f(x) & x1|y1 & x2|y2 & x3|y3 @ x =0, 10}

Sometimes I just need to draw a line linking the coordinates (but not using the f(x) equation) - how do I just draw x1:y1, x2:y2, and x3:y3 and linking all these coordinates with a line?

i.e. the line only exist between the coordinates but do not extend to x=0 and y=0.

Appreciate some help for such a dumb question.

Thanks

I just used the same function but with constant x wherever you desired (here 6 for y and 3 for x)

Thanks. But this appears to draw 3 lines? What i would like to do is to draw one single line between 3 coordinates.

Say (1,20) (2,50) and (5,70) just to name some random numbers. I would like the line will connect these points.

How would i achieve this?

something like this? you use take function and plot it

Hi again. The red line seems to be what i am after. But i m confused by what u did with the take function here and also how you plot it.

Isnt the take function intended to return the nth element from an array of numbers?

It is confusing but at the same time very interesting too!

Edit: I try to run the code but I get this error. Any idea what I have done wrong?

Hi! Maybe you are using an older version. The latest is 7.1.4.
