 ### Data points
 
 For the time-frame requested, `dashboard.js` will use the chart dimensions and the settings of the chart library to find out how many data points it can show.
 
-For example, most line chart libraries are using 3 pixels per data point. If the chart shows 10 minutes of data (600 seconds), its update frequency is 1 second, and the chart width is 1800 pixels, then `dashboard.js` will request from the netdata server: 10 minutes of data, represented in 600 points, and the chart will be refreshed per second. If the user resizes the window so that the chart becomes 600 pixels wide, then `dashboard.js` will request the same 10 minutes of data, represented in 200 points and the chart will be refreshed once every 3 seconds.
