Finding ratio of two columns and then plotting a scatter with the ratio and timestamp

Hello,

I have a test data set attached that includes timestamps and other made up variables for my own practice to get familiar with MatLab.

I am trying to divide the results in column 32 by the corresponding numbers in column 19... so far I have been able to do this using:

data{:,32}./data{:19};

This generates a new table with the values I am interested in and now I want to plot those values as the Y-axis in a scatter with their corresponding timestamp as the X-axis.

Anyone have experience with this? Thanks!

t0 = datetime('26-Jun-2019 00:00:00') ; 
t1 = datetime('26-Jun-2019 23:00:00') ; 
thedates = t0:hours(1):t1 ;
y = rand(size(thedates)) ; 
plot(thedates,y,'.r','MarkerSize',10)
