Dashboard two columns

Hi,

Thank you for your reply.

Yes, let me explain:

I'm using this query:

Perf
|
where CounterName == "% Committed Bytes In Use" and TimeGenerated > ago(30d)
|
summarize avgRAM = avg(CounterValue) by Computer
|
where avgRAM < 50 |
join (Perf
|
where CounterName == "% Processor Time" and TimeGenerated > ago(30d)
|
summarize avgCPU = avg(CounterValue) by Computer
|
where avgCPU < 50) on Computer
|
project-away Computer1

to create a dashboard. If I use the query myself without a dashboard, I can see both columns (first picture). However, when I create a dashboard and use the same query, I can only see the first column.... (second picture)
