Advanced Tutorial Typo/Error

[Ghabri-EL]

In the advanced tutorial, when creating the custom histogram class in HistogramModel.js file, creating chart variable and defining it as constant promps issues with the reset method, as the reset method tries to change the chart variable by creating a new Chart object.

That reset code in the advanced tutorial seems outdated. The reset in the actual implementation in library has been changed in this commit. It's unclear how the change fixed the supposed bug.

And the new code could have been made clearer too. According to https://stackoverflow.com/questions/1232040/how-do-i-empty-an-array-in-javascript

chart.data.labels = [];

would have worked. But this needs testing.

has become outdated because the docs etc. have changed a lot
