Cannot display the histogram. Basicly, I want to plot the data from CSV file. It worked on other csv file.
data = csvread('CorelationCoefficient_All.csv');
x = data(:,1);
histogram(x);

Apologies for the delayed response. My csv file was so big even after compressed. So I deleted few lines of data but still keep the format the same.

Hello Azam,
I tried executing the given code with the provided CSV file. I am able to get the histogram as shown below:
There could be several reasons why you are facing this issue. Here are some possible suggestions to troubleshoot the problem:
1. File Path: Ensure that the path to the CSV file is correct. If the file is not in the current working directory, you should provide the full path to the file.
2. Outdated function: In the newer MATLAB releases, "csvread" is not recommended. You should consider using "readmatrix" or "readtable" instead. Please find the following relevant documentations:
3. Error Messages: Please check for any error messages in MATLAB’s command window. These messages can provide clues about what might be going wrong.
4. Permissions: Check if there are any permission issues with accessing the file.
If none of these suggestions resolve the issue, kindly provide more details about the error message or behavior you are encountering so that we can assist further.
