How to pass different field value for drilldown on piechart?

[nisu]

query : sourcetype=test | chart count by type, vendor | eval type_with_vendor=type.":".vendor | fields type_with_vendor, count, type

I want to show type_with_vendor and count on chart and pass type value on drilldown. How to do this? Is it any way to do?

Any help would be appreciated.

@nishu... How about reversing your eval and chart command.

sourcetype=test 
| eval type_with_vendor=type.":".vendor
| chart count by type, vendor 
| sort - count
