Hi slepore, what exactly is the issue that you are having? do you mean you want all the dates labelled along the x-axis?
Or are you after a date X-axis that doesn't "skip" dates where there is no data. In this case you can go to the Axis tab in the chart properties, and in the dimension axis area, check the box marked "continous".
Dates not included will now show with a 0 figure.
