I'd rather users built their legends using their own data, as supplied to the barColors and labels attributes of the config object on the Morris. Bar constructor. I don't see much value in a callback that gives a user back the exact same data that they've already supplied to us.

I can write a gist if you want something more detailed. Thank you sudodoki for your snippet. Very useful if the graphs are made to be printed. Anyone got solution? Because dima-sh has posted nearly the whole thing thanks!

Possible reasoning for callback: When using default colors and thus not having your own reference for the colors being used.

Incapsulation not relying on options property being available as a property of your chart instance - what if we change the implementation and make options part of a closure? Unified API across chart types right now colors are set through barColors. Also it shows the value right of the text. Hello, How can I change the size font of legend in line chats?

For current charts in master branch. Because many users requested. This does not change public interfaces for constructing elements. Firing and handling click events are done by Morris. Few examples were updated to show the possible usage. The callback functions for each chart type are unified and support rowId and rowData as parameters.

This PR is next on my list to review. It may require some re-work now that the html hover code is in master it could be useful to use the new hitTest methods on line and bar charts, for example.

I've needed to start using tiraeth 's branch for this feature on bar charts and it is working as expected. The api could also place data attributes on the svg elements to pass along the data for a particular point or bar. Placing classes on svg elements would also promote interaction with other page elements.

Imagine a table that listed 4 cars with a graph next to it that had a line for each of those cars that graphed the sales of each of those cars.

When clicking a row on the table, the corresponding line could be highlighted to more clearly distinguish the corresponding data. Utilizing classes and jQuery or another library might add a lot of flexibility without having to manage binding and firing of events, which IMHO would increase the complexity of the current codebase.

Hilight does not utilize css only. So this won't work at all. Also, Morris is using some internal events to show the popup and so on. The only solution is to provide a public api inside Morris that will be available for users, e. Yeah, it totally sucks.

This is an array of objects, containing label and value attributes corresponding to the labels and sizes of the segments of the donut chart.

Note: by default, the segment with the greatest value will be initially selected. You can change the selection using the select index method on the object returned by Morris.

Note 2: as for line charts, if you need to update the plot, use the setData method on the object that Morris. Donut returns. Note: this element must have a width and height defined in its styling. Note: if there are fewer colors than segments, the colors will cycle back to the start of the array when exhausted. This has a significant performance impact, so is disabled by default. Live Example Morris.

A function that will translate a y-value into a label for the centre of the donut. Set to true to enable automatic resizing when the containing element resizes.Google charts can fire events that you can listen for.

Events can be triggered by user actions, such as when a user clicks on a chart. You can register a Javascript method to be called whenever certain events are fired, possibly with data specific to that event. Every chart defines its own events, and the documentation for that chart should describe when each event is fired, what it means, and how to get back any information associated with the event.

This page describes how to register to receive events from a chart, and how to handle them. There is one event that any selectable chart should fire: the select event.

However, the behavior and meaning of this event is defined by each chart. It is important to note that the chart events are separate and distinct from the standard DOM events. To register your event handlers, you call google. Your function should accept a single parameter that is the event that was fired.

This event can have custom information about the event, as described in the chart documentation. Important: If your chart exposes a ready eventyou should always wait for that event to be fired before you try to send methods or receive events from the chart.

These charts might work before they throw a ready event, but that behavior is not guaranteed. Note that this will only register to listen for events for this specific table object; you can only register to receive events from a specific object. Events generally expose information in two ways: by passing information into the handler function as a parameter; or by adding information to a global object. If and how the event exposes information should be described in the documentation for that chart.

Here is how to retrieve both types of information:. If the chart passes data as a parameter to your handling function, you would retrieve it as shown here:. The parameter passed in to your handler will have a property that should be documented for the chart. For an example of a chart that exposes event information this way, see the Table chart's page event. Some events instead change a property of a global object, which you can then request. A common example of that is the "select" event, which is fired when a user selects a part of a chart.

In this case, the code must call getSelection on the chart to learn what the current selection is. More information is given on the select event below.

As mentioned previously, any chart that can be selected should fire a "select" event that works in a standard way to let you retrieve the values of the selected item in the chart. However, there is no absolute requirement that a chart behave this way; check the documentation for your chart. In general, charts that expose the "select" event are designed with the following specifications:. The following example pops up an alertbox with the selected table elements, when an element of a table chart is selected:.

Note that the table chart only fires row selection events; however, the code is generic, and can be used for row, column, and cell selection events. Most charts are rendered asynchronously; all Google charts throw a ready event after you call draw on them, indicating that the chart is rendered, and ready to return properties or handle further method calls.

You should always listen for the ready event before trying to call methods on it after calling draw. In general, charts that expose the "ready" event are designed with the following specifications:. The convention is that charts that do not fire a "ready" event are ready for interaction immediately after the draw method ends and returns control to the user. If your chart does fire a ready event, you should wait for it to be thrown before calling methods on it, as shown here:.

Charts should throw an error event when they encounter some sort of error, to enable you to handle it gracefully.GitHub is home to over 40 million developers working together to host and review code, manage projects, and build software together.

It's a very simple API for drawing line, bar, area and donut charts. I'm unfortunately not able to actively support Morris. 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.

Remember that Morris. Please make your changes in the. You'll need node. I recommend using nvm for installing node in development environments. 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. Note: I'm experimenting with using perceptual diffs to catch rendering regressions.

Sign in to your account. As in my previous PR, new version for these two folks. I've also added callbacks for hover and click events. Currently only one series per donut chart but in future more series will be available to be put there. These charts support 0-valued rows by providing options. Please mind that if minSectorAngle: 5 then sectors with values 0 and 3 will have the same angle in the chart.

Hint: I am very seriously thinking about getting rid of the stroke parameter and handle the spacing between sectors with math instead of path's stroke. Sorry for two commits per PR. Maybe a good idea is to set a parameter like strokeColor accepting RGBA, which can easily solve this problem without doing mess with who like this white stroke spacing. I completely understand you, oesmith. Maybe is time for you to elect one or more fellows to help you maintain the project it's a suggestion.

I do understand your POV. But I think that if you want Morris to be used wider and I think you want some functionality should be changed to use the ones users are used to. I think that tooltips should be controlled by CSS html ones, like in other charts.

Displaying the value and label as you do right now could be controlled by hover event on the chart. I think that you should support the conventional behaviour and give people a way to accomplish more sophisticated changes. And more, I think that donut chart should in near future support multiple series, because that's the purpose of displaying data in donut instead of a pie. My philosophy for Morris. It's the one you reach for when you want to do something quick and simple, without sacrificing aesthetics.

Features like milti-dimensional donut charts and rich interactivity are beyond that philosophy. I'd very much prefer people to be using more advanced visualisation libraries like D3.

Usage simplicity and small amount of code does not imply the lack of some functionaltiy. But I understand you and won't insist on pushing functionality you object to.

Others can always use one of forked repositories mine, for instance if they want to. The hover and click binding would allow for a wide range of customisation, without any added complexity to the current usage.

It's just one function: Morris. Line optionswhere options is an object containing some of the following configuration options. Create an area chart using Morris. Area options. Area charts take all the same options as line charts, and the following extras:.

Note: this element must have a width and height defined in its styling. This is an array of objects, containing x and y attributes as described by the xkey and ykeys options.

Note: ordering doesn't matter here - you can supply the data in whatever order works best for you. Note 2: if you need to update the plot, use the setData method on the object that Morris. Line returns. There's a setData example in the GitHub repo. Timestamps are accepted in the form of millisecond timestamps as returned by Date. By default uses the same values as lineColors pointStrokeColors Colors for the outlines of the series points.

Alternatively, set this to 'auto' to compute automatically, or 'auto [num]' to automatically compute and ensure that the max y-value is at least [num]. Alternatively, set this to 'auto' to compute automatically, or 'auto [num]' to automatically compute and ensure that the min y-value is at most [num].

Hint: you can use this to create graphs with false origins. Set to true or 'auto' to only show the hover legend when the mouse cursor is over the chart. Set to 'always' to never show a hover legend. The function will be called with the index of the row under the hover legend, the options object passed to the constructor as arguments, a string containing the default generated hover legend content HTML, and an object containing the original data for the row as passed in the data option.

Please use postUnits. By default the interval will be automatically computed. The following are valid interval strings: "decade" "year" "month" "week" "day" "hour" "30min" "15min" "10min" "5min" "minute" "30sec" "15sec" "10sec" "5sec" "second" xLabelFormat A function that accepts Date objects and formats them for display as x-axis labels.

Overrides the default formatter chosen by the automatic labeller or the xLabels option. If you list fewer colors here than you have lines in goalsthen the values will be cycled.

If you list fewer colors here than you have lines in eventsthen the values will be cycled. When set to truenull values will break the line and undefined values will be spanned. Note: in v0.

Accepts values between 0. This has a significant performance impact, so is disabled by default. Live Example Morris. The ID of or a reference to the element into which to insert the graph. The data to plot. A string containing the name of the attribute that contains date X values. A list of strings containing names of attributes that contain Y values one for each series of data to be plotted.

A list of strings containing labels for the data series to be plotted corresponding to the values in the ykeys option. Colors for the series points.
