    Beautiful charts for Angular2 based on Chart.js


    This is a fork of ng2-charts from valor-software that fixes some bugs which were not addressed in the original for a long time and this package will be used for Apollo-rocket.

    Usage & Demo

    Sample in below website uses ng2-charts-apollo@1.1.0

    http://valor-software.github.io/ng2-charts/ http://plnkr.co/edit/7fGsiuRjcF0M0Ffeoml2?p=preview


    1. You can install ng2-charts-apollo using npm
    npm install ng2-charts-apollo --save
    1. You need to install and include Chart.js library in application via html or webpack bundler (more options can be found in official chart.js documentation)
    npm install chart.js --save

    Important: Embedding Chart.js in application is mandatory!

    <script src="node_modules/chart.js/src/chart.js"></script>

    Usage & Demo

    Demo and API details of ng2-charts-apollo can be found here: demo and source code.

    Note: For more information about possible options please refer to original chart.js documentation

    • data (Array<number[]> | number[]) - set of points of the chart, it should be Array<number[]> only for line, bar and radar, otherwise number[];
    • datasets (Array<{data: Array<number[]> | number[], label: string}>) - data see about, the label for the dataset which appears in the legend and tooltips
    • labels (?Array<any>) - x axis labels. It's necessary for charts: line, bar and radar. And just labels (on hover) for charts: polarArea, pie and doughnut
    • chartType (?string) - indicates the type of charts, it can be: line, bar, radar, pie, polarArea, doughnut
    • options (?any) - chart options (as from Chart.js documentation)
    • colors (?Array<any>) - data colors, will use default and|or random colors if not specified (see below)
    • legend: (?boolean=false) - if true show legend below the chart, otherwise not be shown


    • chartClick: fires when click on a chart has occurred, returns information regarding active points and labels
    • chartHover: fires when mousemove (hover) on a chart has occurred, returns information regarding active points and labels


    There are a set several default colors. Colors can be replaced using the colors attribute. If there is more data than colors, colors are generated randomly.
