ember-line-graph is a tiny(1.74kb gzipped), zero-dependency ember-addon to draw line charts.

It uses SVGs to create charts so it is scalable and supports animations and gradients.


ember install ember-line-graph


Detailed Docs


  • points - an array of values, example - [1, 10, 45, 3, 4, 6].
  • strokeWidth - width of the SVG path stroke.
  • strokeOpacity - opacity of the line in the chart. A number between 0 and 1.
  • strokeLinecap - Specifies the ending style of the line path. One of butt, round or square.
  • strokeDasharray - Controls the pattern of dashes and gaps used to stroke paths. Refer MDN Docs. Not recommended to use this with animation as the animation will first draw a undashed path and the chart will then turn to dashes.
  • type - line(default) or smooth.
  • smoothness - a number between 1 and 10 to determine the curve around the chart's points. Applicable only when type is smooth.
  • colors - A color or an array of colors for defining the chart's colors. A color can be any valid CSS color value.
  • animation - A boolean to specify if the path should be animated from left to right.
  • animationDuration - A number(in ms) to specify the duration for the animation.
  • animationTimingFunction - Any valid CSS animation-timing-function for the animation.
  • width - A number to specify the width of the chart.
  • height - A number to specify the height of the chart. Optional. Defaults to width/4.
  • padding - A number to specify padding for the chart inside the SVG so that lines are not cut at the edges. Optional.
