Tooltip is not rendering correctly

[shivam-880]

I am trying to make use of this tool in following contrived example and the tool tip doesn't seem to be rendering correctly. Not sure what is wrong. Please suggest!

Demo.js

import React from 'react';
import Tooltip from '@uiw/react-tooltip';
import HeatMap from '@uiw/react-heat-map';

const value = [
  { date: '2016/01/11', count:2 },
  ...[...Array(17)].map((_, idx) => ({ date: `2016/01/${idx + 10}`, count: idx, })),

const Demo = () => {
  return (
        <HeatMap
          value={value}
          startDate={new Date('2016/01/01')}
          rectRender={(props, data) => {
            if (!data.count) return <rect {...props} />;
            return (
              <Tooltip placement="top" content={`count: ${data.count || 0}`}>
                <rect {...props} />
              </Tooltip>
            );
          }}
        />

export default Demo;

import App from './App';

const root = ReactDOM.createRoot(document.getElementById('root'));
root.render(

    <App />
  </React.StrictMode>
);

@jaywcjlove I am doing that already. Did you have a look a the Demo.js I posted in this issue?

 <HeatMap
          value={value}
          startDate={new Date('2016/01/01')}
          rectRender={(props, data) => {
            if (!data.count) return <rect {...props} />;
            return (
              <Tooltip placement="top" content={`count: ${data.count || 0}`}>
                <rect {...props} />
              </Tooltip>
            );
          }}
/>

@iamsmkr I didn't find any issues while looking at the examples: https://codesandbox.io/embed/sweet-aj-jpl6mx?fontsize=14&hidenavigation=1&theme=dark

I was with the same error and was unable to resolve it.

I ended up using react-tooltip

its pretty straight forward:

<div>
  <HeatMap
            value={value}
            startDate={new Date('2016/01/01')}
            rectRender={(props, data) => {
              if (!data.count) return <rect {...props} />;
              return (
                  <rect {...props} data-tooltip-id="my-tooltip" data-tooltip-content={`${data.date}: ${data.count || 0} posts`}/>
              );
            }}
  />
  <Tooltip id="my-tooltip" />
</div>

This may not be a good permanent solution, but i found turning off React.StrictMode fixes this rendering problem. I am using react-heat-map and (@uiw/)react-tooltip with vite, so I changed my main.jsx to look like this:

ReactDOM.createRoot(document.getElementById('root')).render(  
  /* <React.StrictMode> */  
    <App />  
  /* </React.StrictMode>, */  
)

I have the same problem, the tooltip is aways on the top left corner, i am using nextjs.

@mentaLwz follow @goncaloalves solution

Same problem, it also rerenders, the component entirely
