I've been getting an error when I try to replicate the results I should be able to get when using the Chart Macro (in Confluence 4.3.7).
You are attempting to add an observation for the time period January 2011 but the series already contains an observation for that time period. Duplicates are not permitted. Try using the addOrUpdate() method.
I used the two tables that are shown in the Confluence documentation on the Chart Macro that's showing how these two values change over time, yet it seems having two tables with values does not work?
Has anyone gotten this to work? I have been able to get it to show as a "stacked bar", but that has an issue with wanting to show the "month" in the legend as a column with values.
