h2. Overview 
{styleclass: Class=topLink}[top|#top]{styleclass}
Brushing allows users to restrict results in their chart by choosing to *Include* or *Exclude* certain areas. This is a far more interactive method of filtering, as the user defines what they want to see or remove by highlighting the particular area on their chart.


h2. Include
{styleclass: Class=topLink}[top|#top]{styleclass}
Once the chart has been created, you are able to restrict results to the ones you select by:
# Click and drag to highlight an area on the chart
# Select the *Include* option
!keep1.png|thumbnail,border=1!
# You will now notice that the chart has been restricted to only the values you selected in the highlighted range
!keep2.png|thumbnail,border=1!


h2. Exclude
{styleclass: Class=topLink}[top|#top]{styleclass}
Once the chart has been created, you are able to remove results that you select from the chart by:
# Click and drag to highlight an area on the chart
# Select the *Exclude* option
!exclude.png|thumbnail,border=1!
# You will now notice that the chart has removed the values you selected in the highlighted range
!exclude2.png|thumbnail,border=1!


h2. Reset
{styleclass: Class=topLink}[top|#top]{styleclass}
Once the chart has been brushed, you are able to reset results by:
# Click and drag to highlight an area on the chart
# Select the *Reset* option
!reset1.png|thumbnail,border=1!
# You will now notice that the chart has been returned to its original state
