How do I get this to plot in XY graph?

[ldc6]

Hi guys - I'm sure this is a basic question, but I can't seem to get past it.

I have the following:

Function(i):= ( data1(i) data2(i) data3(i) )

Function(0)= ( 5 2 3)

Freq:= 8..10

I want to be able to plot Function(0) vs. Freq on an XY Plot (similar to below pic but w/ connected lines), but I can't seem to get it to work. Any ideas?

5| x
4|
3| x
2| x
1|_ _ _ _
0 8 9 10

Any help would be greatly appreciated.

Thanks in advance

Try

Function(Freq-8)@Freq

Greg- Thanks for your help. I tried what you said and it gives me an error saying that Function(Freq-8) is not a scalar so it doesn't plot anything.

Any more ideas?


Thanks,ldc

You seem to have made it overly complicated, but since you've not given enough details...

The simplest thing to do is to put the values in two 3x1 vectors, one called Y and the other called X, and plot Y against X.

You can do something similar if you use a data table or an Excel component.

IRstuff - Thanks. I did what you suggested and it worked for one value of the index i (i.e. Function(0) vs Freq). Is there anyway to plot Function(i) vs. Freq on an XY plot for all values of i?

Thanks again,

How many do you have?

As I mentioned, data tables or Excel components can be used for inputing data from tests or experiments. The Excel component can easily be used to directly import test data into two columns. Assign two output variables, for Columns A and B. Use a 2x1 matrix with elements X and Y:

(X Y):= your excel component.

The do the plot as before.
