I'm completly new to Matlab and am trying to plot COVID-19 case numbers by country. On the y-axis I want the date, and on the x-axis I want the amount of covid-19 cases. (with lines for different countries)
I've created a datastore, then a tall array from where I have used the gather function to select certain rows of data. I'm not sure how to create a line graph from the table.
  • I know how to label x-axis and y-axis and the title.

The following link may help you plot the data as it is quite straight forward. Trying taking an example which suits your requirement.

The simple answer for one country is just (ignoring the fact that most people would want time along the horizontal axis)
plot(s.Australia,s.Date)
If you want multiple countries, you could loop over the table's count vars and plot using hold on, but this should also work
plot(s{:,2:end},s.Date)
The braces allow you to extract multiple variables (as long as they are the same type), and plot will make separate lines for each column of the double matrix that s{:,2:end} creates. You'll want to add a legend with the country names.
