title: Charting with Dygraphs: Data sampling depending on zoom
body: <p>Although Dygraphs performs very well compared to other solution, when viewing more and more data points, the performance inevitably slows.</p>
  
  <p>I already have all my data loaded locally. Is there a way for Dygraphs to intelligently display a lower resolution (in terms of number of data points) and then show more on zoom? </p>
