Uncaught TypeError: Cannot read property 'y' of undefined on tooltip in piechart #45

Using django-nvd3 version 0.7.7 this is issue is there, but not there in 0.7.4

lgp171188 commented 9 years ago

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;
          return tooltip_str;
          });

Same problem here.

Could this be related to: https://github.com/nvd3-community/nvd3/issues/28

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.

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}
