Anti-aliasing improves chart images by displaying jagged lines as smooth, and affects performance. In applications where performance is critical, use the server.xml setting to prevent charts from being anti-aliased.
To disable anti-aliasing:
In the section <properties>, copy and paste the string:
<property defid="0ad70321-0001-08aa-000000e738090110" name="DISABLE_ANTIALIASING">true</property> <SERVICES app="bq"> ... <service type="BrioQuery"> ... <properties> ... <property defid="0ad70321-0001-08aa-000000e738090110" name="DISABLE_ANTIALIASING">true</property> ... </properties> </service> </SERVICES>
