show numbers in x-axis vertically

Hi guys,
I want to plot some data values according to different days. Data format is like this:
x: 2015-04-10|09:30,
y: a number.
The problem is x values are too long and having lots of data will result messy numbers in x-axis.
Is there any way to show numbers in x-axis vertically?

Hi,

You may try to apply rotate transformation:
