I'm trying to change marker size in a graph

I'm trying to change marker size in a graph but i keep getting this error and dot know how to fix it

Answer 1

[VBBV]

markerSize_types = 12;

[VBBV]

Values need to be numeric and not of character

i need the number to randomly change though. when i put in a number like that it still give me an error

[Walter Roberson]

markerSize_types = 1:5;

Note that Marker Size default is 6 so Marker Size 1 is pretty small.

[VBBV]

markerSize_types = randi([1 12],10) % define range of markersize

markerSize_types = 10×10

9 6 5 6 3 11 1 8 11 2 1 1 4 12 4 3 5 4 3 7 11 5 6 4 11 8 10 8 4 12 9 7 8 9 5 12 5 12 11 7 7 8 10 10 9 9 7 3 12 6 1 7 2 3 5 11 7 9 3 2 10 7 12 10 4 8 12 4 5 4 9 3 1 3 6 3 10 9 4 9 4 5 1 6 3 8 12 10 4 3 11 6 4 9 10 1 5 10 9 8

[r c] = size(markerSize_types);
random_index = randi([1 r*c],1) % randomly inditialize value

random_index = 89

random_markerSize = markerSize_types(random_index) % pick the value using index from type vector

random_markerSize = 4
