Brushing concept not working

[Anonymous]

Hi,

I have a bar chart in my dashboard i am using brushing concept in this chart to get highted bar when it selected (like screen_1.gif) unselected bars will be grayed out.

I am using expresion " = if(rule_name=rule_name, Color(FieldIndex('rule_name',rule_name)),RGB(175,175,175)) " in Background color attribute for expression. I am not getting the Default color for the chart if i wirte this expression here.

Can some one help me to get default color for bars after this expression is applied in the attribute?

It looks that the expression isn't valid and will be therefore ignored from qv. I assume that rule_name isn't always unique and will therefore return NULL - have a look here: It’s all Aggregations.
