I have attached a .csv file which I have created containing time running from 21/11/22 - 22/11/22.
I have also attached a copy of the code i am using to load in this data.
I am not sure if the hh:mm time is correct in the .csv file? I want it to run from midnight on 21/11/22 to midnight on 22/11/22 at hourly intervals. For example, 21/11/22 01:00:00, i want this to be 1am.
I want to plot this data as a time series, showing the time in hours on the x-axis.

You have one line per hour so you can use directly the line index as your time series and plot the associated variable according to it.
timeSeries = 0:length(excelTime);
plot(timeSeries,variableToPlot)

I am using this function to plot the code
function plot_21_OC(data21)
plot(data21.t,data21.MSLP,'b-+') %for example
ylabel('MSLP')
I have attached an image of the figure. The data for MSLP is plotting, im just confused how i would get the appropriate times to plot on the x-axis.

Ran in:
tt = readtimetable("208cw3_21OC.csv",NumHeaderLines=5,VariableNamingRule="preserve")
tt = 25×6 timetable
