Is your feature request related to a problem? Please describe.
Add the possibility to switch between simple element tooltip to multi/element tooltips like vertical or horizontal cursors or crosshair.

Describe the solution you'd like

The user/developer can select the type of tooltip that's better conforms for the chart use to enable the following possibilities:

• single tooltip with single value
• single tooltip with multiple values (with all data thats belongs to the same data point or to the same X or Y axis value, eg stacked charts see: In stack chart show all stacked values on tooltip #68)
  
  See also https://www.chartjs.org/docs/latest/general/interactions/modes.html as a reference

Describe alternatives you've considered

Various solutions can be applied:

• remove the existing listeners to graphic elements and use directly mouse coordinates to mapping series data values getting series values from inverted x and y scales or use some spatial index for faster searches like https://github.com/mourner/flatbush
• draw a hidden layer of grouped elements with listener attached to it (can be slow and can only works on vertical and horizontal cursors.

design note: the tooltip could be crowded specially with multiple splitted series.
extra: this can solve the following issue: #58

Additional context

TVSB, charts used by Stack Monitor and any other chart that use react-vis in kibana currently has the possibility to include a vertical cursor on the chart instead of the tooltip.
