Please add title tag inside histogram(bars) polygon tag and put text of original number where bar was created.
This is for browsers that can view title, when user hover mouse over bars and can get detailed number.
Here is original key and number formatted as formaty is set
<polygon points="..."> <title>Monthly 123 456,78</title> </polygon>
Please clarify. Are you talking about polygons "set object N polygon ..." or are you talking about histograms "plot $DATA with histogram" or something else? Are you asking for a variant of the hypertext support that attaches pop-up text to polygons rather than points?
I mean "plot $DATA with histogram" feature and maybe boxes too if it not broke anything.
Title inside polygon is not visible normally.
When using title element all modern browser can show title value natively when user move mouse over histogram bar. This acts near like hypertext, but its native and view title from whole polygon area.
When using rowstacked and have many stacked bars its nice to see real value of bar easily and title tag can do it. This feature request is from finance analysis needs.
