rowIndex really should be a number better than or equivalent to zero, and under the volume of rows as returned from the getNumberOfRows() method. columnIndex must be a selection increased than or equivalent to zero, and under the number of columns as returned with the getNumberOfColumns() system. price [

An assortment of objects, each one with the amount of the column index to kind by, and an optional boolean property desc. If desc is set to genuine, the precise column will likely be sorted in descending get (the default is ascending order). The primary item is the first column by which to type, the second a single could be the secondary, and so on. Which means when two values in the first column are equal, the values in the subsequent column are as opposed, and so on. Instance: sortColumn([ column: 3 , column: one, desc: true , column: six, desc: genuine ]) will type first through the 4th column (in ascending buy), then column two in descending get, and then column 7 in descending order. The returned benefit is definitely an assortment of figures, Every range can be an index of the DataTable row. Iterating over the DataTable rows from the get with the returned array will end in rows purchased by the specified sortColumns. The output can be employed as enter to DataView.setRows() to immediately change the exhibited set of rows in a very visualization. Notice that the sorting is certain to be stable: this means that should you sort on equivalent values of two rows, exactly the same sort will return the rows in exactly the same buy anytime.
within the underlying desk will not be mirrored via the perspective, and might cause unanticipated actions in the see; you'll need to make a new DataView in the DataTable to select up these modifications. Incorporating or getting rid of rows
The ChartEditor class is accustomed to open up an in-webpage dialog box that allows a user to customize a visualization about the fly. To make use of ChartEditor:
. Columns needs to be a similar type in equally tables. All specified keys must match in accordance with the rule presented by joinMethod
If the row house is null, then the choice can be a column; if the column house is null, then the choice is usually a row; if equally are non-null, then it is a particular knowledge merchandise. You'll be able to connect with the DataTable.getValue() method to obtain the value of the chosen item. The retrieved array is often handed into setSelection(). Illustration
The DataTable object is accustomed to hold the data handed into a visualization. A DataTable is really a standard two-dimensional table. All information in Each and every column have to have the identical info style. Each individual column provides a descriptor that includes its data type, a label for that column (which could be exhibited by a visualization), and an ID, which may be used to check with a certain column (as a substitute to using column indexes). The DataTable item also supports a map of arbitrary properties assigned to a certain worth, a row, a column, or the whole DataTable. Visualizations can use these to guidance extra options; by way of example, the Table visualization uses custom made more info Attributes to Allow you to assign arbitrary course names or styles to unique cells. Just about every mobile inside the desk retains a value. Cells can have a null worth, or a value of the kind specified by its column. Cells optionally usually takes a "formatted" Edition of the info; this is a string Edition of the information, formatted for Exhibit by a visualization.
columnIndex ought to be a number larger than or equal to zero, and lower than the number of columns as returned because of the getNumberOfColumns() approach.
Sets various cell Qualities. Some visualizations assistance row, column, or mobile Houses to change their Show or actions; begin to see the visualization documentation to see what Attributes are supported. rowIndex need to be a range better than or equal to zero, and fewer than the quantity of rows as returned from the getNumberOfRows() method.
] is the value assigned to the specified cell. To prevent overwriting this worth, set this parameter to undefined; to obvious this price, established it to null. The kind of the value is dependent upon the column style (see getColumnType()): In the event the column sort is 'string', the value needs to be a string.
drawChart() This method makes a chart in an individual contact. The benefit of utilizing this technique is always that it demands a little bit considerably less code, and you will serialize and preserve visualizations as textual content strings for reuse.
