When to use
To build this chart, define the required and optional data fields as follows:
Columns – Dimensions and measures that you want to use in the visualization. The order of the columns is used in the visualization query. In other words, you write the code considering the column’s order (the first column, the second column, and so on).
Other – (Optional) List of columns to be included in the query scope but not used in the visualization layout.
Actions are not supported for the Custom viz as a source. However, you can select the Custom viz as a target for actions except for highlighting.
You can use the Filter widget with the Custom viz. For details, see Filter.
In the Code & resources section, click Code Manager.
On the Custom JS tab, before adding the code, review the params object information.
The function draw(params) is called once before the renderer is used and the params object is passed.
Properties in the params object:
container – The DOM div element.
columns – An object that contains column metadata.
data – An array with the dataset metadata.
colors – An array with palette colors in hex format.
formatValue – A built-in format value method.
The console.log(params) loads the params object into the web browser console after you save this tab and visualize the widget.
For example, you can learn how the columns are loaded: ‘c1’ is the first column and ‘c2’ is the second column selected in the Columns field.
On this tab, you can add the links to external JS libraries and CSS files. The external resources are loaded in the order that you add them.
To remove a resource, point to the row, and then click Delete.
