Why Campaign ROI on the Dashboard is always not available?

[Amy Sung]

We use SugarCRM Cmmunity Edition Version 5.2.0j (Build 5804)

After adding on the Campaign ROI on the Dashboard of Repot, the data is always not available.

After I type in every information of campaign including Budget,Expected Revenue,Actual Cost and
Expected Cost. I can see the chart inside Campaign panel,which there is one button for "View ROI".
But can't see on the dashboard.

Can anyone help? Thanks!!

You need to have run a successful Campaign ... emails say

then click on the pencil on the top right of the dashlet and select the campaign that you want to report on

Save the dashlet ... the ROI should appear
