Merging two dataset for Chart (XML fetch)

Hi,

I am creating a report for MS CRM 2011 Online and are using Fetch XML to create dataset's. I would like to combine two dataset's to create a chart with the values.

I have read something regarding Merge for datasets but dont understand it. The entities are not related in CRM if it matter.

Can someone please help me .

Dataset 1

<fetch version="1.0" output-format="xml-platform" mapping="logical" distinct="false">
  <entity name="new_budget">
    <attribute name="new_budgetar" />
    <attribute name="new_budget_totalt" />
    <attribute name="new_budgetid" />
    <attribute name="new_budget_09" />
    <attribute name="ownerid" />
    <attribute name="new_budget_10" />
    <attribute name="new_budget_11" />
    <attribute name="new_budget_05" />
