Zero-mileage weeks not showing in 6 monthly graph (Read 191 times)

I analyse my running by miles/week, with weeks shown as bars in a bar chart over the past 6 months. The thing is, when the first week in the bar chart has zero mileage (which is does from time to time, due to illness or injury) it disappears from the chart, and the chart instead begins with the next available week that has a non-zero mileage. It would be helpful if this chart could show a consistent 6 months/26 weeks irrespective of whether I ran during the initial week or not. 

Thanks
