<h1>Data</h1>
|
|
|
|
<p>
|
|
One of the starting points of the visualizations of vis.js is that they can deal with dynamic data, and allow manipulation of the data. To enable this, vis.js includes a flexible key/value based <code>DataSet</code> and <code>DataView</code> to handle unstructured JSON data.
|
|
</p>
|
|
|
|
<p>
|
|
By providing a <code>DataSet</code> with data to the visualizations, they can subscribe on changes in the <code>DataSet</code> and automatically reflect the changes in their view. Changes in the data can be caused by a server pushing updates to a client, or by other interactive components in the web application. Vice versa, data can be manipulated in one of the visualizations. For example a REST-client can listen for changes and automatically write changes to the server. Or changes can be propagated to other parts of the web application.

|
</p>

|
|
<h2>DataSet</h2>
|
|
|
|
<p>
|
|
A <code>DataSet</code> can be used to store JSON objects by id. Objects can be added, updated and removed from the DatSet, and one can subscribe to changes in the <code>DataSet</code>.
|
|
The data in the <code>DataSet</code> can be filtered and ordered, and fields (like
|
|
dates) can be converted to a specific type. Data can be normalized when
|
|
appending it to the <code>DataSet</code> as well.

<h2>DataView</h2>
|
|
|
|
<p>
|
|
A <code>DataView</code> offers a filtered and/or formatted view on a DataSet.
|
|
One can subscribe to changes in a <code>DataView</code>, and easily get filtered or
|
|
formatted data without having to specify filters and field types all
|
|
the time.
