Newbie for Atlassian Analytics. Need learning material and learning path for building dashboard

[Venkatesh Parthiban_G]

Am trying to create a dashboard in Atlassian analytics. For which one of the chart below is the logic 

I want to build a report like this which need to show total Feature Percentage based on below logic It should count the sum of original estimates of story, task and bug with labels FEATURE, TECH_DEBT & INNOVATION. No other tickets Lets assume if the Total estimate is 1000 hours (only the ticket that has any of the above mentioned labels) Tickets with Label "FEATURE" is 500 hours Ticket with Label "TECH_DEBT" is 300 hours Ticket with Label "INNOVATION" is 200 hours It should show FEATURE - 50 %

I can either show Feature , Tech Debt and innovation percentage in pie chart or separate Single Chart Indicator for each different labels. 

Also it wil be fine if learning path or dashboard is provided for the same ?
