We all want to know how much we made last month and this month or how much we did last year this month so we can compare Company or business goals! Any business man who wants to invest a business is going to ask monthly sales chart and we need to satisfy first our self with a nice design and correct value of inputs.
We can clearly and professionally see from these green and red arrows that business monthly sales are how up and down so we can gather some specific information for any purpose of usage such as investors or our very own management.
I can also make some custom pdf export by using these data for better visualized.
