When hovering over a data point in Chaco, I would like a small text box to appear, with the text I desire. Also, when I click on a data point (or close enough), I would like my program to take a certain action. I have seen relevant parts of the Chaco documentation, but implementing them has proved difficult. Any help would be appreciated.
Thanks.
Focusing first on the first (hover->textbox) issue, can you better explain what you've tried so far and how it's not working? E.g.,
from enthought.enable.tools import hover_tool
tool = hover_tool.HoverTool(theplot, callback=showtext)
etc? There's a more complex example of hover-tool use here (shows a PlotToolbar rather than just a textbox) which you might be able to adapt.
