Tall svg?

[zoell]

Hi Marcus,

I am trying to put a relatively tall SVG (it is like 440px X 825px) but for some reason the SVG panel won't extend my SVG's div to the bottom of the panel.

Here is my SVG:

<svg x="0px" y="0px" width="440" height="825" viewBox="0 0 440 825">
<style type="text/css">
    svg { background-color: red; }
	.st0{fill:#999999;}
	.st1{fill:#1A1A1A;}
</style>
<rect id="bgbox" x="11" y="13" class="st0" width="420" height="802"/>
<rect id="box4" x="22" y="22" class="st1" width="113" height="313"/>
<rect id="box3" x="22" y="492" class="st1" width="113" height="313"/>
<rect id="box2" x="308" y="24" class="st1" width="113" height="313"/>
<rect id="box1" x="308" y="494" class="st1" width="113" height="313"/>
</svg>

I put a red background just to see what is going on, and this is how it looks like:

I am wondering how it would be possible to make this SVG the full height of this panel?

Thanks, zoell

sorry for my late reply. As it seems a Grafana panel cannot get higher than wide. Maybe it helps to adjust your viewbox to be square. Maybe 825 by 825. Please let me know if this helps.

cheers Marco

Hi Marco,

Thanks for your reply. Originally I wanted to put in a very high SVG 440x825px that is why I have setup that panel to be tall, I also played with the viewbox and tried 825 by 825 but does not matter what I try the div that holds the SVG is always resized to square.

I noticed that in the code the plot-canvas div that is always resized to a square, while the outer divs like svg-panel and the panel-content's height looks OK:

Looks like it should be possible to have a high panel, or not?

Thanks, zoell

You are exactly right. It's actually my fault since I do the following in rendering.js

 function resizePlotCanvas() {
    var width = elem.width();
    var height = elem.height();

    var size = Math.min(width, height); // <--- ERROR HERE

    var plotCss = {
      top: '10px',
      margin: 'auto',
      position: 'relative',
      height: (size) + 'px'
    };
    plotCanvas.css(plotCss);
  }

I am busy today and over the weekend. I will look into it by Monday next week

Hi Marco, May I ask if you had the chance to check this? Many thanks!

Sorry, haven't had any time yet.

It seems like we can just use the height here, instead of the weird min(width, height), like this?

function resizePlotCanvas() {
    var width = elem.width();
    var height = elem.height();

    var plotCss = {
      top: '10px',
      margin: 'auto',
      position: 'relative',
      height: (height) + 'px'
    };
    plotCanvas.css(plotCss);
  }

I am really sorry, but I won't get around this issue in the next days. If you want to test it with your own setup you may checkout the repo and fiddle around. If you succeed I would be grateful for a PR. Thank you.

I have tested this and seems to be working.

But we have to make sure that it does not break the layout of other people‘s dashboards. I‘m sure the assignment was for a reason. I just don‘t remember which .. I know bad commenting. I guess it should be optional with the current setting as default.

You can add a checkbox like "Advanced panel size support" and use the above mentioned solution only when it is checked. This way if someone wants a tall SVG it will be possible but you can keep the support for others.

Should be fixed now in version 0.3.3. Will post it to the Grafana repo too. I would recommend though, that you remove the static size from the svg root node. This way the SVG will resize to the container correctly.

<svg viewBox="0 0 440 825">

Hi Marcus, May I ask if you could push this out to the Grafana repo?
