Show percent difference between the 12 month moving average of a month vs the previous month

Show percent difference between the 12 month moving average of a month vs the previous month

Hi, 

I was wondering if this was possible in Zoho. I have created a report that shows the moving average of a count of items in a table based on the 12 months previous. I would like the text above each data point to show the percent difference between the moving average of the month of the data point vs the moving average of the previous month. Ultimately I would like to place these data points in its own chart to see the trend of percentage changes. I know you can show the % difference between previous values of different columns and dates, but can you show the % difference between to moving averages plotted on a chart.

Thank you,
Trevor
