I have to plot an x-y profile (graph) in visualisation. How can I do it?

You could prepare an array Y1[X1], Y2[X2]...etc. Next use Histogram with presentation options Curve. You will see the x-y spline curve.

Hello Igor, I'm interested about the x,y profile plot.

I try to do a curve histogram with an array like

Y:ARRAY[1..10] OF INT:=1,2,3,5,6,8,1,2,4,8;

but I see an empty histogram.

can you explain how it works.

thanks.

I would do it with pieces of line and put them in an array.

much like your histogram but i can make drawings and even openings.

i made example with array and rectangles. changed them to lines so i have begin and endpoint.

also possible with line command with scale and direction.

scale is length of line

hello everybody, I try to do it in this way

scale start 0

scale end 10

mainscale 1

subscale 1

unit

variable Y[1]

type curve

arraybegin 1

arrayend 10

bandwidth 90

Y:ARRAY[1..10] OF INT:=1,2,3,5,6,8,1,2,4,8;

but in run mode the graph is empty...

can you help me?

thanks a lot.

Bye

See attached picture and project (V2.3.9):

Thanks a lot.

It works. in my example was wrong only the variable.

I set "variable Y[1]" , the first item of the array and not the array

"variable Y"...

I will use it!

Bye
