<div class="p">
This chart graphs estimates against actual recorded cycle times. Since
estimates can change over time, we're graphing the estimate at the time that the story started.
</div>
<div class="p">
The #{color_block '--estimate-accuracy-chart-completed-fill-color'} completed dots indicate
cycletimes.
<% if @has_aging_data %>
The #{color_block '--estimate-accuracy-chart-active-fill-color'} aging dots
(click on the legend to turn them on) show the current
age of items, which will give you a hint as to where they might end up. If they're already
far to the right then you know you have a problem.
