Add a setting which will allow 'gaps' in a line of there is no data present for a given X-Axis http://community.powerbi.com/t5/Desktop/Non-continuous-line-chart-data/m-p/13746
Please review this. Showing a continuous line when the x axis is a date is factually incorrect. It implies there are values at the null date points when there are not. Also, it would be a great feature to also offer the null "gaps" to go to 0 rather than just show the gap.
