I am trying to create a line chart from an excel file which has data from Jan to Dec. The line chart draws a line where it plots all the amount in the ascending order. So that results in a chart where Apr may appear before Jan if Apr has the less amount.

So i want to know that can i do to not let line chart sort by amount and show the months in sequential fashion.

And where can i learn about all the functions that can be used in zoho reports?
