Hi everyone. I have this much of information ![](https://us1.discourse-cdn.com/elastic/original/2X/4/4800fac0058a5ec984d4fc2677e264e9c8a9f312.jpg) and I want 2 values (WLNode and JSession) to be displayed on a graph. I want to see amount of JSession of each WLNode to be more specific. I really tried to figure it out myself but I couldn't, so I would appreciate any help. Thanx in advance. ---

Go to visualize, add a ?Bar chart? or datatable if you please. Change the metric from count to sum and select the JSession field for it. Then Split the bar/datatable rows on term-\>WL Node. Hope this makes sense. ---

Thank you very much, I appreciate it. But when I change metric from count to sum Filed list appears but it's empty, only when "Unique count" type of aggregation selected Field list has all my fields. Any other ideas? ---

Sum , average and other such aggregations can only be performed on number types. If JSession is not in the field list , then the field is probably mapped as a string. Check your index mapping. Unfortunately (as far as I know) you cant change a field mapping once data is loaded.. you'll have to re-index your data. ---

Yep, you're right, it's string, actually I thought about that, hoped it can conver data on the fly, will look for a way to convert this field to number then will try to do like you advised. Thanx again! ---
