Thread Subject: Plot strings

I want to customize my axis of a plot with a string array of time values. Any ideas how to do this?

time = ['15:14:12','15:14:13','15:14:14','15:14:15'];
value = [ 4.5, 6.5, 10, 4 ];

plot(value);

%% Now i need to set the x axis to be the time values in
%the above array.

Please help.

You might want to look for the function "format_ticks" in the file_exchange. It may do what you want to do.

Presuming that time is a cell array -- the expression you show would
have time end up as one long string:

timenums = datenum(time);
plot(timenums, value);
datetick('x, 'HH:MM:SS');
