Line property error with time series plot

I am trying to produce a simple, time series plot of wind speeds for a specified date and time range. I am importing data from a csv file, but running into a error that says 'There is no A property on the line class'. It looks like it is assigning 'A' to the wind variable, but I'm not sure why. Here is my code:

Wind='FloNOAANBDCSep18WindSpd';

wind=Wind(:,7);

t1=datetime(2018,8,31,23,10,0);

t2=datetime(2018,9,30,23,0,0);

time=t1:minutes(10):t2;

plot(time,wind,'r')

title('Wind Speed at CMAN CLKN7')

ylabel('m/s')

legend('NDBC')

Thanks for suggestions.

Hi John,

The below line is only gives the char array of a file name. You are not actually importing your data.

Wind='FloNOAANBDCSep18WindSpd';

You should read your csv and get it to your workspace first. You can use below functions:

[Wind,txt,raw] = xlsread('FloNOAANBDCSep18WindSpd.csv'); % for numeric(Wind) or raw data
%or
Wind=readtable('FloNOAANBDCSep18WindSpd.csv'); % for table
%or
Wind = csvread('FloNOAANBDCSep18WindSpd.csv') % For numeric

% You can also use full file path all of these three functions: 
'C:\users\documents\FloNOAANBDCSep18WindSpd.csv'
