Dates in a charts x-axis

Please open the enclosed workbook.
Two questions:
- how can I avoid that the dates not appearing in the source is showing in the chart? That is the case for 2/8 and 3/8.
- I often experience that the dates in the chart are shown as the dates numeric codes in Excel. How can I avoid that?
Please note that dates in col. D is reffering to col. B
