I have a dashboard with numerous charts on it and earlier today I was able to reduce the data on a particular by clicking on an individual series. After working on underlying data on other reports, the chart that I initially tried to reduce now no longer lets me reduce it. For example:
When I first opened the dashboard, I could click on the December Totals to have that data removed from the chart (clicking again brings it back into the chart). A couple hours later, now that functionality no longer works. I did clear my cache and that doesn't work. Again, for this particular chart, I did not touch the underlying data yet this function no longer works.
