How to fetch x and y values from canvas chart

  I have plotted a canvas chart from a csv file.
  Now I would like to fetch the data (x and y values) and print the values in a label when I hover on .

  I initially tried to pass the data from the API objet named ‘datapoints’ but the printed value of it was ‘[object Object]’

  I know that there is already a label which does that,(which presents a value when we hover on it) but I want to present that data in a custom label.

  Is it possible ? If yes, please guide me in how to proceed.

  Are you looking for mouseover event, where you can get the currently hover dataPoint’s x and y values like e.dataPoint.x and e.dataPoint.y. Or else you can look into toolTip contentFormatter.

  If this doesn’t suite your requirements, could you please provide us a pictorial representation to understand better.
