问题
I'm using react-vega-lite
.
In official examples:
https://vega.github.io/vega-lite/
https://vega.github.io/react-vega-lite/
https://vega.github.io/react-vega/
vega-lite
(without react) has a tooltip by default
react-vega
allows to handle onSignalTooltip event.
So, I have 2 questions:
1) Is it possible to turn on tooltip with react-vega
(react-vega-lite
)?
2) Does react-vega-lite
support onSignalTooltip
or I need to switch to Vega?
回答1:
Add vega-tooltip
package as a dependency, then import the Handler
class from it and pass an instance through the tooltip
parameter of the VegaLite
component:
import { Handler } from 'vega-tooltip';
...
<VegaLite spec={spec} data={barData} tooltip={new Handler().call} />
