Passing variables to plot function
3 views (last 30 days)

I have the following plot function
plot([2,7],[3,3],'lineWidth', 40);
Instead of [2,7], I want to pass two variables d1 and d2 that has a set of values stored in it. Can someone please help me with that?

Well, it would seem pretty straightforward,
plot(d1,d2,'lineWidth', 40);
assuming X, Y values are in d1, d2, respectively, and they're the same length vectors.
See
doc plot % for details on using it

I'm sure I don't understand from the description. What are the sizes of the various variables and what do you actually want plotted?
The general answer is that plot expects an X and Y array of commensurate length; if vectors orientation doesn't matter. You can do whatever manipulations you need with the variables to build the desired X and Y, plot doesn't care how you write the arrays as long as it is valid syntax that could be written to store the result as a variable.

let see it what you want
>> d1=[1 3 5 6] % create a vector as x for plot
d1 =
1 3 5 6
>> d2=[4 5 0 10] % create a vector as y for plot
d2 =
4 5 0 10
>> plot(d1,d2,'lineWidth', 40);
do not use [] in d1 and d2
here is the output plot,
