Item Time in Process

More Charts: Item Time in Process (Calendar Days) chart

1/ The Cycle Time by Start Date series values are hard-coded to a range of 152 values, and if I paste my own data in with fewer than 152 values then the chart breaks. (The date axis will start from 1900).

Also:
2/ Would a legend be helpful on this chart?
3/ Would a different title be helpful? Perhaps "Item Time in Process by Started and Completed Dates)"
