New datagrid in v6.21

In version 6.21 a new datagrid object has been added. This makes it easy to add static or dynamic data tables to your pages. It can be used whether you use the canvas or SVG libraries or entirely standalone.

License

RGraph can be used for free under the GPL or if that doesn't suit your situation there's an inexpensive (£129) commercial license available.

I tried many methods, and one of them:

<script>

    function graf(){
        new RGraph.SVG.Bar({...}).wave();
    }

    const resizeObserver = new ResizeObserver((object) => {

        console.dir('...' );//info if action is catch
        object[0].target.innerHTML = '';//...optional no matter
        graf();
    });

    resizeObserver.observe(document.getElementById('chart-container' ) );
</script>
Each time graf() is called again, the graph and its continer of SVG tag disappear from the HTML document. It doesn't matter whether innerHTML cleanup is used. Console.dir('...') is called but with no chart, it disappears. With listeners do the same. It doesn't matter if it's onmouseover etc. No allert is generated, no error, just gone and only console('...') is repeated...
console('...') idicated that action is called propelly but chart is gone and not created by graf() where RGraph.SVG.Bar({...}).wave(); must be called.

PS.
I wrote the question again because I can't add an answer to the original post, there is some error
