When creating graphs and charts of events over time, certain important data is not displayed. Specifically, if the event being tracked does not occur on a particular date, then the chart simply skips that date. Instead, there should be an option to include that date with a value of 0. In some cases, seeing 0 events for a date is important. It may even indicate success (like number of escalation events or lost opportunities). So, it is important to see the days when 0 happens reflected on the graph. Without this, the charts can be very misleading.
