tQuery('SELECT A,D WHERE D > 100 ORDER BY D') This returned DataTable can be copied, modified, or copied into a DataView the same as any other DataTable. When you send a query to a Chart Tools Datasource, a successful reply is a DataTable instance.

Var data = new () ĭata.addColumn('string', 'Employee Name') Here are a few examples of creating the same data table using different variations of this technique:

Depends on the speed of the browser, and can be slower than JSON literal strings with larger tables (about 1,000+ cells).

Not as useful as building a JSON literal string to pass into a DataTable constructor when programmatically generating the page on a web server.

Good for generating the table in the browser, and less prone to typos than the JSON literal method.

You can specify the data type and label of each column.

You can also add or remove rows additional rows or edit cell values individually. You can add empty rows and populate them later.

Add one or more rows, optionally populated with data.

There are several different ways of creating and populating a DataTable:Įmpty DataTable + addColumn()/addRows()/addRow()/setCell() Supports calculated columns, which are columns with a value calculated on the fly by combining or manipulating other columns. Is source data does not contain referencesĪ live reference to a DataTable any changes in the DataTable data is immediately reflected in the view.Ĭan be passed into a chart as a data source Rows and columns can be hidden and revealed repeatedly.Ĭan return a DataTable version of the view

Cannot be populated from scratch must be instantiated with a reference to an existing DataTable.ĭata is a reference to an existing DataTable, and does not consume space.Ĭan add/edit/delete rows, columns, and data, and all changes are persistent.Ĭan sort or filter rows without modifying the underlying data. Here is a brief comparison of the two classes: DataTable Or reorder rows or columns quickly without modifying the linked, original data. That provides a read-only view of a DataTable, with methods to hide In some cases, you might see a JavaScript literal or JSON version of a DataTable used, for instance when data is sent over the Internet by a Chart Tools Datasource, or as a possible input value for a ChartWrapper.

DataTables and DataViewsĪ chart data table is represented in JavaScript by either a DataTable object Read your chart's documentation to learn what data format it requires. A scatter chart, however,Įxpects a table consisting of two numeric columns, where each row is a point, and the two columns are the X and Where each row describes a slice, and the first column is the slice label and the second column is the slice value. Each cell also has an optional map of arbitrary name/value pairs.ĭifferent charts use tables in different formats: for example,Ī pie chart expects a two-column table with a string column and a number column, If a formatted value is supplied, a chart will use the actual value for calculations and rendering, but might show the formatted value where appropriate, for example if the user hovers over a point. For example: a numeric column might be assigned the value 7 and the formatted value "seven".

Cells - Each cell is an object containing an actual value of the column type, plus an optional string-formatted version of the value that you provide.

Rows - A row is an array of cells, plus an optional map of arbitrary name/value pairs that you can assign.

See the DataTable.addColumn() for a list of supported data types.

A column can be referred to in code either by zero-based index, or by the optional ID. The label is a user-friendly string that can be displayed by the chart the ID is an optional identifier that can be used in place of a column index. Columns - Each column supports a required data type, plus an optional string label, ID, pattern, and map of arbitrary name/value properties.Table-level properties aren't currently used by charts. Table - An array of columns and rows, plus an optional map of arbitrary name/value pairs that you can assign.

Here is a more complete list of the supported elements and properties of the table see the Format of the Constructor's JavaScript Literal Parameter for more details: Index or a unique ID that you can specify. Where row is a zero-based row index, and column is either a zero-based column Here's a simplified representation of a populated two-column data table:ĭata is stored in cells referenced as ( row, column), Create a new DataTable, then call addColumn()/addRows()/addRow()/setCell()Īll charts store their data in a table.This page discusses the internal data representation used by charts, the DataTable and DataView classes used to pass data into a chart, and the various ways of instantiating and populating a DataTable.
