Drawings

Drawings (shapes) are the tools that can help you analyze the charts and make clear annotations to them. The drawings toolbar is located on the left panel. Follow the Drawings List article for a complete list of tools included in the drawing toolbar.

Style customization​

Each drawing tool has its own default properties, such as color and size, that users can change in the UI.

Style customization

You can also customize the drawing style using the API. Refer to the Drawing Overrides article for more information.

Drawing toolbar​

You can show/hide the drawing toolbar on the fly as follows:

widget.activeChart().executeActionById("drawingToolbarAction");

Note that the toolbar is hidden in the fullscreen mode. To display the toolbar, enable the side_toolbar_in_fullscreen_mode featureset.

Favorite tools​

You can specify a default list of favorite drawings using the favorites property in Widget Constructor.

In the UI, users can mark drawings as favorites using the Add to favorites button. The selected drawings are added to Favorite Drawings Toolbar that appears on the chart. If you do not want users to specify favorites, you should disable the items_favoriting featureset. As a result, the Add to favorites button will be hidden in the UI.

Custom restrictions​

You can hide some drawings from the toolbar or apply custom restrictions to the chart. To do this, use the drawings_access property of Widget Constructor. For example, you can choose which tools will be shown to users or hidden/disabled from them.
