Vue Chart - Overview
A tooltip is a small pop-up rectangle displaying information about a series point that the user pauses on. By default, the information is the point value, but it is possible to display anything in a tooltip.
All properties configuring tooltips are collected in the tooltip object. For example, to enable the tooltips, assign true to the enabled property of this object.
- <template>
- <DxChart ... >
- <DxTooltip
- :enabled="true"
- />
- </DxChart>
- </template>
- <script>
- import DxChart, {
- DxTooltip
- } from 'devextreme-vue/chart';
- export default {
- components: {
- DxChart,
- DxTooltip
- }
- }
- </script>
Properties declared in the tooltip object apply to all tooltips in the Chart. If you want to customize a specific tooltip, assign a function to the customizeTooltip property. This function must return an object with properties for the tooltip that you want to customize.
- <template>
- <DxChart ... >
- <DxTooltip
- :enabled="true"
- :customize-tooltip="customizeTooltip"
- color="yellow"
- />
- </DxChart>
- </template>
- <script>
- import DxChart, {
- DxTooltip
- } from 'devextreme-vue/chart';
- export default {
- components: {
- DxChart,
- DxTooltip
- },
- methods: {
- customizeTooltip (pointInfo) {
- return pointInfo.value > 100 ? { color: "red" } : { };
- }
- }
- }
- </script>
