As Tom said, using table calculations for MoM or YoY change is probably the best method.
Please see the attached workbook, what I have done is used the discrete date parts of Year and Month in the order date and done a table calculation on a specific dimension (in this case, Year of Order Date):
I have created sheet 2 to show the direction of the breakdown of the table calculation. Please right click on the sales table calculation and select 'Edit Table Calculation', you should see more details as to how this was calculated. (Please ensure that the calculation assistance is on). You'll find the areas highlighted in yellow show you the logic/direction behind the calculation. In the below screenshot, it's the difference between January 2011 and January 2012, and then difference between January 2012 and January 2013 etc.
In the MoM chart, to hide certain months and years, please right click on the year in the year header and select hide.
Then please do the same for the months which you need to hide.
