How to :: add meta information in code mode¶
This is only available from the code mode
When you have a legend pane you could want to add some meta information for a given selection.
meta configuration key will help you achieve that. Just specify
the column names that have to be displayed.
meta: [ "column 1" , "column 2" ]
For charts with groups like the horizontal barchart or vertical barchart
you have the key
metaSerie, which allows you to enter different meta
according to the serie. Simply list the columns you want to use as a
meta, and they will appear next to the label / serie for which you’ve
entered a number.
metaSerie: [ "meta 1" , "meta 2" ]
In the mapchart, meta is located in the zones configuration block (see mapchart doc for further detail).
