I have been using chart.filter([new Date x, new Date x]) to set the range of the chart brush for a play function I am writing. It looks fine on the bar chart as the selection moves properly but unfortunately the selection is not visualized in my graphic properly. I use dimension.top(Infinity) on filtered to send the data to the visualization function but instead of reflecting the set filter range it is aggregating each time it is changed.
For example filtering year a to year b will visualize 3 points. When chart is filtered to second set of years: year b to year c (3 points), it visualizes the new points between those two years but also includes those from year a to b (6 points, I want to show just those 3).
I am wondering if anyone can help with this issue?
Or maybe I am overlooking a dc function and implementing the filter wrong?
