Create a measure with date

Hi Experts,

I am creating a report that has a date slicer and a measure calcualting as following:

mesuare_name = Total sales/ ( total day in month of date chosen on date slicer) * MTD of the date chosen on the date slicer!.

i would like to see the trend of this measure day by day but i dont know how to do it, so could anyone help me?

Thank in advanced.

Best regards,
J.
