title: Chart.js: different dataset size
body: <p>I need to display what I think is a pretty common use case: A line chart showing e.g. daily and hourly averages covering one week.</p>
  
  <p>One dataset has obviously 7 data points, the other has 168.</p>
  
  <p>I have not been able to find an example or a documented option that would allow for this. Sure - I can configure almost anything regarding the look&amp;feel, but when it comes to the data size, both datasets are expected to have as many data points as there are labels.</p>
  
  <p>I would like to have labels only for the dataset with the less datapoints (in this example: daily avg), and the other (168 data points) would simply draw a thin line and should not add aynthing else to the chart (no vertical bars etc.)</p>
  
  <p>Is this possible with Chart.js?</p>
