show both ytd by month& mtd by day in a dashboard by using month slicer

Hi friends,

I have a month slicer and 2 measures including Sales_MTD and Sales_YTD, now i need to show up both in a dashboard to see:

- A Clustered Column chart to show Sales_MTD by day

- A Clustered Column chart to show Sales_YTD by month

However, when i select a month( i.e. when i select March) on the slicer i only show the Sales_YTD for March but i need show both Sales_YTD for Jan,Feb,March in a chart. If i select multiple month on slicer, the YTD chart can show correctly but the MTD-chart will incorrect. Please help me to resolve this issue- select a month to show Sales_YTD by month

Regards,
J.
