Display chart with saved Data using JsChart

Hey guys,

I'm making a financial application that allows the user (a company) to add different incomes or expenses with a date for each one of them. Then the user can generate a chart representing the data already entered. There are 3 types of charts: Income Expense Gross Revenue

I'm also looking to add the option for the user to select the date range of the data he's looking to see, but i don't know if it's possible.

Also i'm using JsChart to generate the chart, let me know if there's another better way.
