I created a dashboard with a query looks like this :  index=cbclogs sourcetype = cbc_cc_performance source="/var/log/ccccenter/performancelog.log" Company IN ($company_filter$) LossType IN ($losstype_filter$) QuickClaimType IN ($QCT_filter$) |eval minsElapsed=round(secondsElapsed/60,0)| timechart median(minsElapsed) by LOB. Suppose LOB has string values like :  "A", "B", "C", "D" ,"E","F","G" ,"H", currently , all values will be shown in the Y axis on the right side , how can I combine "A","B","C" as "A" , "D","E","F" as "E" and "G","H" as "G", so , the right side Y axis has only three values and won't affect the correctness of the dashboard. Actually , I am not sure whether should I call this right side colourful column Y axis.           Thanks a lot ! ... View more
