Have you read the examples at <create-a-table>? It shows building a histogram from table data; nothing much different than using plot instead.
Show us what you've tried and where you ran into problems...
doc plot

i guess you have the data in a txt file so you will have to use textscan and then plot
input = textscan(fileID,'%s%f%f%f%f','HeaderLines',1,'Delimiter', ' ');

Ah...perhaps you're right; I interpreted that the OP already had a table (Matlab style)...
Your textscan isn't likely going to work, however, if the file is as shown. Try
fmt=['%{MMM yyyy}D' repmat('%f',1,4)]; % one datetime, four floats
c=textscan(fid,fmt,'headerlines',5,'collectoutput',1);
'headerlines' is either 3 or 5, depending on whether the file includes the title lines or not...this will leave OP with a datetime cell array and then a cell array of doubles for the data.
If OP were to clean up the file to have just the column headers and the data, should be able to use readtable and get an internal table directly.
