Dynamic Chart Ranges without Pivot Table

Hello
I have a spreadsheet with dates in colum A and numbers in columns B to D. The dates span a full year and I have charted those dates and their values on a line chart. I want to be able to provide two drop downs or a free text field where the user can select two months they want to display in the chart and this will update the chart data accordingly.

Is this possible without using pivot tables?

Thanks
