Uncaught TypeError: Cannot read property 'y' of undefined on tooltip in piechart about django-nvd3 HOT 5 CLOSED

The error is happening on the line "var y = String(graph.point.y);" of the generated JavaScript code

  chart.tooltipContent(function(key, y, e, graph) {
      var x = String(key);
          var y = String(graph.point.y);

          tooltip_str = '<center><b>'+x+'</b></center>' + y;

Same problem here.

Could this be related to: nvd3-community/nvd3#28

from django-nvd3.

Can no longer see this issue on upgrading to django-nvd3 0.8.2 and modifying the code as per the demoproject django application. So closing this.

from django-nvd3.

But then why not updating the readme accordingly?
Updating chartdata in views.py with the following fixed it for me:

extra_serie = {
    "tooltip": {"y_start": "", "y_end": " cal"},
}
chartdata = {'x': xdata, 'y1': ydata, 'extra1': extra_serie}
