The apex:chartTips component is used to define tooltips that appear when a user hovers over data series elements in a chart. It offers more configuration options than the default tooltips displayed by setting the tips attribute of a data series component to true.
The apex:chartTips component must be enclosed by a data series component such as apex:barSeries, apex:lineSeries, or apex:pieSeries. When defining the apex:chartTips component, you can specify the content of the tooltip using HTML, as well as configure the tooltip's position and appearance.
Here is an example of how to use apex:chartTips in a bar chart:
php<apex:chart height="400" width="600" data="{!data}"> <apex:axis type="Numeric" position="left" fields="data1" title="Axis Title"/> <apex:axis type="Category" position="bottom" fields="name" title="Axis Title"/> <apex:barSeries axis="left" xField="name" yField="data1" tips="true"> <apex:chartTips height="50" width="120"> <apex:outputText value="{name}: {data1}"/> </apex:chartTips> </apex:barSeries> </apex:chart> In this example, the apex:barSeries component includes the tips attribute set to true, indicating that tooltips should be displayed when a user hovers over a data series element. The apex:chartTips component is enclosed within the apex:barSeries component, and its height and width attributes are set to define the size of the tooltip. The content of the tooltip is defined by the apex:outputText component, which displays the name and data1 values of the data series element being hovered over.
