Contributors wanted

I'm unfortunately not able to actively support Morris.js any more. I keep an eye on the issues, but I rarely have the time to fix bugs or review pull requests.

If you're interested in actively contributing to Morris.js, please contact me on the email address above.

Requirements

  • jQuery (>= 1.7 recommended, but it'll probably work with older versions)
  • Raphael.js (>= 2.0)

Usage

See the website.

Development

Very daring.

Fork, hack, possibly even add some tests, then send a pull request :)

Remember that Morris.js is a coffeescript project. Please make your changes in the .coffee files, not in the compiled javascript files in the root directory of the project.

Developer quick-start

You'll need node.js. I recommend using nvm for installing node in development environments.

With node installed, install grunt using npm install -g grunt-cli, and then the rest of the test/build dependencies with npm install in the morris.js project folder.

Additionally, bower is required for for retrieving additional test dependencies.
Install it with npm install -g bower and then bower install in the morris project folder.

Once you're all set up, you can compile, minify and run the tests using grunt.

Note: I'm experimenting with using perceptual diffs to catch rendering regressions. Due to font rendering differences between platforms, the pdiff tests currently only pass on OS X.

Random browser hang/crash using Area chart (on Chrome)

I am experiencing random (intermittent) freezes and crashing when rendering an area chart in my app. Sometimes it is on the initial creation - other times I "empty" the div then create a new area chart.

One time I did get evidence of an infinite loop in raphael - Error parsing d H1810 << my best memory of the repeating error.

Unfortunately I'm not getting the error msg anymore in console - chrome is just hanging.

Here is my code to create the area chart:

var chart = this.line =  Morris.Area({
                    padding: padding,       // eg 10
                    element: $el,              // a div
                    data: data,                  //   [] length = 72 - see sample below
                    xkey: 'tm',
                    ykeys: ['wk','av','rst','ex'],
                    labels: ["Working","Available","Rest","Exception"],
                    lineColors: ["blue","gray","red","green"],
                    // lineWidth: null,
                    // pointSize: null,
                    pointFillColors: ["blue","gray","red","green"],
                    // pointStrokeColors: null,
                    ymax: "auto "+(sdc.ymax+2),        // eg 20
                    ymin: 0,
                    smooth: false,
                    hideHover: true,
                    //parseTime: null,
                    //postUnits,
                    //preUnits,
                    dateFormat: function(t) {
                        return util.dts(t);
                    },
                    //xLabels:
                    xLabelFormat: function(t) {
                        return "";
                    },
                    xLabelMargin: 0

                });

example data element:

av: 2
ex: 0
nc: 1
nm: 2
rst: 0
tm: 1362551400000
wk: 0

My div is styled like this:

<div class="wall-chart" style="left: -26px; width: 1828px;">

and is also position: absolute and height: 100% inside another div:

<div style="height: 78px">

That parent div has padding.

Any ideas? Most of the time (8/10 times) the chart renders properly.

Add horizontal barchart option

You can use a horizontal barchart by using the option horizontal = true. This fixes #110. Quite a lot of code had to be added to make this work. Please let me know if you think something should be handled differently. This also includes the fix I supplied in #447, since it was really small. So it fixes #382 as well.

Define multiple line graphs in one JS file

I'm having trouble defining 2 line graphs in one JS file. The graphs are not shown on the same html pages.

I've tried:

Morris.Line({
      element: 'graph_by_hour',
      data: $('#graph_by_hour').data('alerts'),
      xkey: 'hour',
      ykeys: ['alerts'],
      labels: ['Alerts']
    }, {
      element: 'graph_by_priority',
      data: $('#graph_by_priority').data('alerts'),
      xkey: 'created_at',
      ykeys: ['high', 'med', 'low'],
      labels: ['High', 'Medium', 'Low'],
      lineColors: ['#E00B0B', '#1B94E0', '#69CF89']
    });

and

Morris.Line({
      element: 'graph_by_hour',
      data: $('#graph_by_hour').data('alerts'),
      xkey: 'hour',
      ykeys: ['alerts'],
      labels: ['Alerts']
    });
    Morris.Line({
      element: 'graph_by_priority',
      data: $('#graph_by_priority').data('alerts'),
      xkey: 'created_at',
      ykeys: ['high', 'med', 'low'],
      labels: ['High', 'Medium', 'Low'],
      lineColors: ['#E00B0B', '#1B94E0', '#69CF89']
    });

but whichever graph is defined second does not work.

The data looks like this for graph_by_hour and similar for graph_by_priority:

[{"hour":0,"alerts":3},{"hour":1,"alerts":5},{"hour":2,"alerts":12},{"hour":3,"alerts":4},{"hour":4,"alerts":4},{"hour":5,"alerts":4},{"hour":6,"alerts":4},{"hour":7,"alerts":9},{"hour":8,"alerts":2},{"hour":9,"alerts":3},{"hour":10,"alerts":5},{"hour":11,"alerts":5},{"hour":12,"alerts":4},{"hour":13,"alerts":4},{"hour":14,"alerts":7},{"hour":15,"alerts":3},{"hour":16,"alerts":2},{"hour":17,"alerts":3},{"hour":18,"alerts":3},{"hour":19,"alerts":5},{"hour":20,"alerts":0},{"hour":21,"alerts":3},{"hour":22,"alerts":2},{"hour":23,"alerts":3}]

and the whole graphs.js file:

(function() {

  jQuery(function() {
    Morris.Line({
      element: 'graph_by_hour',
      data: $('#graph_by_hour').data('alerts'),
      xkey: 'hour',
      ykeys: ['alerts'],
      labels: ['Alerts']
    });
    Morris.Line({
      element: 'graph_by_priority',
      data: $('#graph_by_priority').data('alerts'),
      xkey: 'created_at',
      ykeys: ['high', 'med', 'low'],
      labels: ['High', 'Medium', 'Low'],
      lineColors: ['#E00B0B', '#1B94E0', '#69CF89']
    });
  });

}).call(this);

Round Y-Axis numbers to a Nicer Format

Hi,

So my area chart looks like this:

Screen Shot 2013-01-17 at 07 29 57

But the axis numbers are not round and nice numbers people like to see, like 250 and 500. We can tweak this behaviour.

Is it possible to group in bar chart?

(BTW, it's currently not possible to view any of the samples on JS Bin. The message "This bin needs a pro account" is displayed.)

But we have the need to group bar charts. Specifically, I want two show two related bars next to each other. Is this supported?
