Create A Dashboard Instance After you have created your data, you can instantiate your dashboard object. Create Control And Chart Instances Define as many instances you need for each control and chart that will be part of the dashboard. A few tips about configuring controls and charts: You must give all controls a filterColumnIndex or filterColumnLabel to specify which column of your google.
DataTable the control operates on in the example above, the control operates on the column labeled Donuts eaten , Use the state configuration option on controls to initialize them with an explicit state when they are first drawn. Establish Dependencies Once you have instantiated both the dashboard and all the controls and charts that will be part it, use the bind method to tell the dashboard about the dependencies that exist between controls and charts.
Draw Your Dashboard Call the draw method on the dashboard instance to render the entire dashboard. Programmatic Changes After Draw Once the dashboard completes the initial draw it will be live and respond automatically to any action you perform on it such as changing the selected range of a control slider that is part of the dashboard.
The following example shows such a case. Dashboard Represents a collection of collaborating controls and charts that share the same underlying data. Constructor Dashboard containerRef containerRef A reference to a valid container element on the page that will hold the dashboard contents. Methods Dashboard exposes the following methods: Method Return Type Description bind controls , charts google.
Dashboard Binds one or more Controls to one or more other dashboard participants either charts or other controls , so that all of the latter are redrawn whenever any of the former collects a programmatic or user interaction that affects the data managed by the dashboard.
ControlWrapper instances defining the controls to bind. ChartWrapper instances defining the charts the that will be driven the by the controls. Extended description Events The Dashboard object throws the following events.
Name Description Properties error Fired when an error occurs when attempting to render the dashboard. One or more of the controls and charts that are part of the dashboard may have failed rendering. The ready event will also fire: after the completion of a dashboard refresh triggered by a user or programmatic interaction with one of the controls, after a programmatic call to the draw method of any chart part of the dashboard. The supported properties of the JSON object are shown in the following table.
If not specified, you must set all the appropriate properties using the set The google. You can use either JavaScript literal notation, or provide a handle to the object. The state collects all the variables that the user operating the control can affect. For example, a range slider state can be described in term of the positions that the low and high thumb of the slider occupy. You can use either Javascript literal notation, or provide a handle to the object.
If this is a Google control, the name will not be qualified with google. So, for example, if this were a CategoryFilter control, it would return "CategoryFilter" rather than "google. This will return null until after you have called draw on the ControlWrapper object or on the dashboard holding it , and it throws a ready event.
The returned object only exposes one method: resetControl , which resets the control state to the one it was initialized with like resetting an HTML form element. May be a qualified name, such as 'vAxis. Pass in the class name of the control to instantiate. If this is a Google control, do not qualify it with google. So, for example, for a range slider over a numeric column, pass in "NumberRangeFilter".
This is not shown anywhere on the control, but is for your reference only. To unset an option, pass in null for the value. Note that key may be a qualified name, such as 'vAxis. Events The ControlWrapper object throws the following events. Name Description Properties error Fired when an error occurs when attempting to render the control.
If you want to interact with the control, and call methods after you draw it, you should set up a listener for this event before you call the draw method, and call them only after the event was fired.
Alternatively, you can listen for a ready event on the dashboard holding the control and call control methods only after the event was fired. None statechange Fired when the user interacts with the control, affecting its state. For example, a statechange event will fire whenever you move the thumbs of a range slider control.
To retrieve an updated control state after the event fired, call ControlWrapper. None ChartWrapper Refer to google. The following notes apply when using a ChartWrapper as part of a dashboard: Do not set the dataTable , query , dataSourceUrl and refreshInterval attributes explicitly. The dashboard holding the chart takes care of feeding it the data it needs.
Do set its view attribute to declare which columns, out of all the ones present in the dataTable given to the dashboard, are relevant for the chart, as shown in Create Control and Chart Instances. Controls Gallery Filters are graphical elements that people can use to interactively select which data is displayed on your chart.
The selected values must be a set of the overall selectable values defined by the values option any extraneous one will be ignored. If the CategoryFilter does not allow multiple choice, only the first value of the array is retained.
It is mandatory to provide either this option or filterColumnLabel. If both present, this option takes precedence.

Collaborator Author. This is from October? Has there been any movement on this? I know this is a low priority enhancement, but still Everyone's response when we show them the charts created is 'How do I print it?
I am developing a web server related to computational biology based on the Google charts and it is crucial for our users to be able to easily include the charts into their presentations. Currently they are forced to download the data and manually produce an alternative plot, which defies the purpose of the charts. I just need to add some additional information for the saved file.
