Returns the colors for the text of the label for the tooltip item. Returns the colors to render for the tooltip item. Returns text to render for an individual item in the tooltip. This will be called for each item in the tooltip. Returns text to render before an individual label. Returns text to render before the body section. Returns text to render as the title of the tooltip. Returns the text to render before the title.
For functions that return text, arrays of strings are treated as multiple lines of text. This is the primary model that the callback methods interact with. Namespace:, items marked with Yes in the column Dataset override can be overridden per dataset.Ī tooltip item context is generated for each item that appears in the tooltip. For all functions, this will be the tooltip object created from the Tooltip constructor. Namespace:, the tooltip has the following callbacks for providing text. This function can also accept a fourth parameter that is the data object passed to the chart. Must implement at minimum a function that can be passed to (opens new window). # Filter CallbackĪllows filtering of tooltip items. This function can also accept a third parameter that is the data object passed to the chart. # Sort CallbackĪllows sorting of tooltip items. Color boxes are always aligned to the left edge. These options are only applied to text lines. The titleAlign, bodyAlign and footerAlign options define the horizontal position of the text lines with respect to the tooltip box. The following values for the yAlign setting are supported. The following values for the xAlign setting are supported. If these parameters are unset, the optimal caret position is determined. The xAlign and yAlign options define the position of the tooltip caret. You can also define custom position modes. 'nearest' will place the tooltip at the position of the element closest to the event position. 'average' mode will place the tooltip at the average position of the items displayed in the tooltip. Position of the tooltip caret in the Y direction. Position of the tooltip caret in the X direction. This will force the text direction 'rtl' or 'ltr on the canvas for rendering the tooltips, regardless of the css specified on the canvas True for rendering the tooltip from right to left.
