qChartView only shows a single List’s data
When trying to configure qChartView to display the data for two Lists in the same site, even though you add both Lists to qChartView through ezEdit, when you try to configure the graph you only see the dropdown columns of one of the Lists (the first List added to the Web Part). The two Lists do not have a common column to sort by.
If you want to configure two Lists in qChartView, both Lists must have the same columns. This is by design.
<p>WORKAROUND:</p><p> Modify the field/column name of one List to match the other.</p>
