Why does my .csv file create spaces between each of my data points? It makes it to where I cannot graph precipitation against the date.

1 view (last 30 days)
% I have also attached the data I am trying to extract the data from
clearvars
clear all
clc
% Open data
fid=fopen('2022BRPREC.csv','r');
data=textscan(fid,'%s%s%s%s%s%s%s','headerlines',1,'delimiter',',');
fclose=(fid);
% Name 2022 Variables
date22=data{4};
prec22=data{5};;
figure
cc=plot(date22,prec22);

You're defining the columns as strings so the output is going to include whitespace.
You want something like:
...
data = textscan(fid,'%s%s%{MM/dd/yyyy}D%f%f%f%f%f','headerlines',1,'delimiter',',');
...

...
data=textscan(fid,'%s%s%{yyyy-MM-dd}D%f%f%f%f%f','headerlines',1,'delimiter',',');
...
This is what my code with the error looks like
