Is it possible to create a bar chart where the width of each bar represents a unique date range (a continuous range, though never overlapping)? The height of the bars would be an average value of data collected for that date range.

The reason I am looking for a solution like this is because I have data points that were gathered over different shifts. But not all shifts worked were the same length. So, when graphing, the shorter shifts have the same visual impact as the longer shifts.

Thanks,
