Hi! I have a SVG waterfall chart which needs to be updated. I have already tried to use reset or clear but the chart just disapear and doesn't redraw when I call .draw() function. Thanks!

About

RGraph is a JavaScript charts library based on HTML5 SVG and canvas. RGraph is mature (over 15 years old) and has a wealth of features making it an ideal choice to use for showing charts on your website.

Download

Get the latest version of RGraph (version 6.18, 1st June 2024) from the download page. You can read the changelog here. There's also older versions available, minified files and links to cdnjs.com hosted libraries.

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've updated the RGraph.SVG.reset() function so download the updated core library from this link:

https://raw.githubusercontent.com/heyesr/rgraph/main/libraries/RGraph.svg.common.core.js

And try using it and see if it makes a difference.

This is what I was using to get a new waterfall chart displayed - by resetting the SVG tag, removing it from the DOM and creating a new chart from scratch.

<div id="cc" style="width: 500px; height: 500px"></div>

<script>
    // Create the initial chart
    waterfall = new RGraph.SVG.Waterfall({
        id: 'cc',
        data: [1,2,3,4,5,6,7,8,9,10],
        options: {
        }
    }).draw();

    // Clear the canvas after two seconds
    setTimeout(function ()
    {
        RGraph.SVG.reset(waterfall.svg);

    }, 2000);

    // Draw the second chart
    setTimeout(function ()
    {
        waterfall = new RGraph.SVG.Waterfall({
            id: 'cc',
            data: [4,8,6,4,5,-5,-4],
            options: {
            }
        }).draw();
    }, 5000);
</script>
