It would help to have your data rather than an image of it.
In the interim, try something like this —
imshow(imread('Screen Shot 20....42.20 PM.png'))
% T1 = readtable('YourFile.csv')
T1 = table(['16/02/2024';'16/02/2024'], ["11:37:39AM"; "11:37:40AM"], [11.9420; 11.9440], 'VariableNames',{'LogInterval','VarName2','VarName3'})
LogTime = datetime(T1.LogInterval, 'InputFormat','dd/MM/yyyy') + timeofday(datetime(T1.VarName2, 'InputFormat','hh:mm:ssa'))
LogTime.Format = 'yyyy/MM/dd HH:mm:ss'
T1 = addvars(T1, LogTime, 'Before',1)
T1 = removevars(T1,[2 3])
VN = T1.Properties.VariableNames;
figure
plot(T1.LogTime, T1.VarName3)
grid
xlabel(VN{1})
ylabel(VN{2})
That should work.
