OpenSpending

The WordPress plugin focuses more on simplicity of use than feature completeness. If you are interested in more configurations, please consider using the OpenSpending visualisation library directly (the plugin creates a clean user interface on top of that library).

Unfortunately, in the current implementation of the bubbletree visualisation there are a few errors. One is the assumption that it is impossible to drill down (click on) bubbles with only a single child (irrespective of if that child has more children). Another is the assumption that all children will have at least two other sibling bubbles. The third, and possibly the biggest problem is that because the bubbletree works via the URL more than one bubbletree per page is not possible.

For both the bubbletree and the bar charts, the OpenSpending icons are automatically loaded for dimensions defining COFOG classifications. Simply choose the COFOG dimensions as the drilldowns.

Yes! You could for example use the bar chart and just choose your time dimension. Note that this will write out the full date. If you want to for example only show the time as the year, you would have to change the drilldown dimension in the generated shortcode from time to year.

Not necessarily. The plugin tries to do automatic inflation adjustment based on consumer price index data available for last year. If it cannot find the needed data then it doesn't do the adjustments and falls back to historical values.
