Hi,
I am having trouble in plotting, I want to plot the graph where x-axis are names and y-axis numbers but I am getting the error below. what is solution for that.
Code:
close all; clear all; clc;
file = ["C:\Users\Alphagamma\alphagamma.xlsx];
for i = 1:numel(file)
a=readtable(file(i));
names = a{:,3}
values = a{:,5}
end
figure()
plot (names,values)
Error:
>> figure()
plot (names,values)
Error using plot
Invalid data argument.

You can only plot numeric data. But x label you can change with the help of xTickLabels
set(gca, 'xTickLabels', XlabelStr);

Hi,
what am I doing wrong here I added the piece of code you mentioned!
is there no way it will read the names from the excel ?
Code:
set(gca, 'xTickLabels', names);
figure()
plot (names,values)
Error:
plot (names,values)
Error using plot
Invalid data argument.
