What is the alternative of xtickformat() in the R2015a version?

4 views (last 30 days)
Hello,
I was trying this code on the version R2015a:
t = 0:seconds(30):minutes(3);
y = rand(1,7);
plot(t,y)
xtickformat('mm:ss')
But I got this error:
Undefined function or variable 'xtickformat'.
How do I solve it please?

datetick('x', 'mm:ss');
Note that in that release (and earlier releases) each time you zoom or pan, you will need to re-execute the datetick() command in order to update the tick labels properly.
In sufficiently new versions, if datetime or duration objects are used as the x axes, then the axes labels will be automatically updated as you zoom or pan. However, that facility had not been implemented in R2015a.

You are incrementing by minutes(0)
You probably meant minutes(60) . However, 0:minutes(60):hours(10) would be 11 entries and you only have 10 entries in y.
