Chart showing up blank about layercake HOT 10 CLOSED

When you look at the DOM tree, what’s there? Is there an svg with a path attribute?

In your screenshot, there’s a mismatch between the dimensions shown in the browser window versus what’s computed. Maybe try getting rid of the negative margin top, if that’s hiding elements in your layout.

I would also try creating a hardcoded svg element to see if that draws given your current setup.

The screenshot above shows the expanded DOM tree. I don't see anything except an empty HTML document.

I'd first try to see if any SVGs can render. The iframe in the screenshot is a svelte thing for capturing resizes. Just to be sure, scroll down some more and see what else is in there. Can you make a minimal reproduction? Without that, it's going to be hard to debug remotely.

Replacing with an SVG seems to work fine.

<style>
  .chart-container {
    width: 100%;
    height: 300px;
  }
</style>

<div class="chart-container">
  <svg width="400" height="180">
    <rect x="50" y="20" rx="20" ry="20" width="150" height="150" style="fill:red;stroke:black;stroke-width:5;opacity:0.5" />
    Sorry, your browser does not support inline SVG.
  </svg>
</div>

<!-- { filename: 'js/App.svelte' } -->
<script>
  import { LayerCake } from 'layercake';

  // Define some data
  const points = [
    {x: 0, y: 0},
    {x: 5, y: 10},
    {x: 10, y: 20},
    {x: 15, y: 30},
    {x: 20, y: 40}
  ];
</script>

<style>
  .chart-container {
    width: 100%;
    height: 300px;
  }
</style>

<div class="chart-container">
  <LayerCake
    debug={true}
    data={ points }
    x='x'
    y='y'
  >
    <!-- Components go here -->
  </LayerCake>
</div>

Weird. Well, I'll keep poking around. I was curious if anyone had tried this with Tauri.

That's the expected behavior based on the Svelte code you've posted.

You have to include components where it has the comment <!-- Components go here -->. The LayerCake component is measuring the extents of your data and creating scales. It will only render when you've passed in components that create SVG, HTML or Canvas elements.

For example, import the Svg layout component and copy the ScatterSvg component into your project from here: https://layercake.graphics/example/Scatter.

Ah, I guess I missed that initially. I can't test it for a few days, but this is almost certainly my issue.

Sounds good. If you do have the time to post a minimal reproduction, I've wanted to play around with SvelteKit + Tauri so it would be informative to see what your setup is.

Just published my (very much WIP!) application: https://github.com/kdumontnu/clouseau

Thanks for your help!

Ah great! I’m glad it worked out!
