Spacing Xticks in plotting a function

Question

0 个投票

Dear all,

I have problems with my plot. Please open the figure.

my x is in this format = '07-Sep-2021 13:02:32';

When i run this command:

set(gca, 'Xtick', (0:100:1200), 'XTickLabel', (interval(1,1):minutes(3):interval(101,1)));

I receive this output

Error using matlab.graphics.axis.decorator.DatetimeRuler/validateTicks

Value must be a vector of increasing datetime values.

Of course values in interval are in a crescent order.

How to space lines in the x-axis properly?

"Value must be a vector of increasing datetime values."

set(gca, 'Xtick', (0:100:1200), ...

Those values above are not datetime values. They are double precision numeric values.

Assuming 'interval' contains datetime values, try,

set(gca, 'Xtick', interval(1,1):minutes(3):interval(101,1), 'xlim', interval([1,101],1))

You can set the datetime tick format using datetick.
