d3.js & nvd3.js -- How to set y-axis range

Question

Found a solution.

Appending .forceY([0,100]) to the instantiation of the chart forces the axis to take on the range specified in the array.

From the example here http://nvd3.org/livecode/#codemirrorNav

Appending .forceY([0,100]) to the chart variable works.

As the name should suggest, this adds the values in the array to your y domain, it does not set the y domain to [0,100]. So if you set this to [0,100] and your data's domain is -10 to 110, the domain will be [-10,110].

Now if you wanted the domain to be [0,100] even if your data is larger you can use chart.yDomain([0,100]) ... BUT usually you want your domain to include or your data, so I highly recommend using chart.forceY instead of chart.yDomain. As you'll see, one of the most common uses for forceY is forceY([0]) to make 0 always in the domain.

Hope that helps you understand what the function is actually doing, and arboc7, this should explain why it doesn't work in making the range smaller than the data set's.

For stacked area charts, .forceY([0,100]) does not work. Use instead .yDomain([0,100])

If you mean setting the y-domain (the range of numbers that should be displayed) for stacked area charts, this works for me:

nv.models.stackedAreaChart()
  .x(function(d) {...})
  .y(function(d) {...})
  .yDomain([0, maxY])
...
