Using either d3.js or a javascript method, is there a way to draw the nested circle (#snap-points) on top of the line group?
<g id='panel-group'>
<rect id='panel-rectangles' />
<circle id='snap-points' />
</g>
<g id='line-group>
<line/>
</g>
document.getElementById('snap-points').appendChild(document.getElementById('line-group'))
Should do it i.e. reparent the snap-points element as a child of the line-group.

I have a JavaScript application that modifies an inline SVG. I have multiple elements within the SVG that all need to have the same background image applied to them. Elements (paths) are positioned in the SVG via transform attributes. Presently I am using a pattern fill on the elements. Is there any way to achieve the effect of the pattern staying stationary irrespective to element transforms?
Currently I have this:
I want this:
(note: I hard-baked the path in the second photo, which can't be used in the application)
Edit:
The patterns are currently applied like so:
<defs>
<pattern id="metallicgold" x="0" y="0" width="1240" height="775" patternUnits="userSpaceOnUse">
<image xlink:href="img/gold-texture.png" />
</pattern>
</defs>
The transforms on elements look like this:
<path transform="translate(-445.0000396775016 -1950.3326958481455) rotate(317.2309439443859 2926.326416015625 2926.32666015625) scale(1 1)" style="fill: url('#metallicgold'); stroke: none;" d="M1951.326416015625,1951.32666015625L3901.326416015625,1951.32666015625L3901.326416015625,3901.32666015625L1951.326416015625,3901.32666015625L1951.326416015625,1951.32666015625Z" x="0" y="0"></path>
If you want a constant background as you transform shapes, you should consider using a filter with userSpaceOnUse filterUnits, unless the transforms are easy and apply to all elements filled, in which case, you can use patternTransform on the pattern to reverse the transform on the elements.
<svg width="800px" height="600px" viewBox="0 0 4000 4000">
<defs>
<filter id="brick" x="0" y="0" width="4000" height="4000" filterUnits="userSpaceOnUse">

<feComposite operator="in" in2="SourceGraphic"/>
</filter>
</defs>
<g filter="url(#brick)">
<path transform="translate(-445.00 -1950.33) rotate(317.23 2926.32 2926.32) scale(1 1)" stroke="none" fill="red" d="M1951.326416015625,1951.32666015625L3901.326416015625,1951.32666015625L3901.326416015625,3901.32666015625L1951.326416015625,3901.32666015625L1951.326416015625,1951.32666015625Z" x="0" y="0"></path>

<rect x="1250" y="500" width="300" height="300" fill="blue"/>

I am using Chartist.js for some charts and I need to target some elements inside the chart in order to generate some elements that are related to them. Is there a way to target such deeply nested child elements inside the "chart1". I need to target the "g" elements with the classes of "ct-series-a", "ct-series-b", etc... But since there are multiple charts on the page that ALSO have elements with these class names, I need to only target the ones that are contained in the chart with the id of "chart1".
HTML Mock-up
<div id="chart1" class="ct-chart">
<svg>
<g>
<g class="ct-series ct-series-a"></g>
<g class="ct-series ct-series-b"></g>
<g class="ct-series ct-series-c"></g>
</g>
</svg>
</div>
Somthing like this should help you.
const chart1 = document.getElementById("chart1");
const seriesA = chart1.getElementsByClassName("ct-series-a")[0]
console.log(seriesA.className)
// I did use className , for reducing console data to show u the result in console .
<div id="chart1" class="ct-chart">
<svg>
<g>
<g class="ct-series ct-series-a"></g>
<g class="ct-series ct-series-b"></g>
<g class="ct-series ct-series-c"></g>
</g>
</svg>
</div>
Main Question:
Is there a way to set a static width and height on <g> elements so that they don't get effected by transform attribute done on its parent view-box <svg> element?
i.e.
<svg id="viewbox" transform="translate(1,5)scale(2)">
// continuously gets the transform attr via js upon zoom event
<g>
<path "the shape of a triangle"/>
<path same/>
<path same/>
<path same/>
<path same/>
</g>
</svg>
I want everything under the <g> element to translate according to the zoom event transform values that the <svg> view-box receives, but not scale the dimensions of the <g> element. So that it looks like the screen is zooming into one section of the view-box, but without the <g> elements changing dimensions.
Instead of applying transformations to the svg element tag (svg) directly, you can use a group tag (g) to translate everything and a rectangle tag (rect) to scale only your 'viewbox'.
<svg width="1000" height="1000" xmlns="http://www.w3.org/2000/svg">
<g transform="translate(1, 5)">
<rect
id="viewbox"
fill="black"
width="100"
height="100"
transform="scale(2)" />
<!-- your elements down here -->
<rect
fill="grey"
width="20"
height="20"
x="10"
y="10" />
</g>
</svg>
Hope this help :)
I need to display use elements in my SVG graphic.
When I try to use them from within a g element it doesn't work.
In a little demo it looks like the use element works outside of g elements.
Here the fiddle (you can scroll down to the use elements to see the demo):
http://jsfiddle.net/3dacnxdb/2/
Why is it like this? How can i display them from within a g element?
(My graphic is made out of many modules I need the gs to seperate them)
I appreciate any help!
<svg id="graphic">
<defs>
<clipPath id="icon-cp">
<rect x="0" y="0" width="150" height="100" />
</clipPath>
<image id="icon-sprite" width="969" height="293"
xlink:href="http://i.stack.imgur.com/TPx5h.png" />
<g id="icon2" clip-path="url(#icon-cp)">
<use xlink:href="#icon-sprite" transform="translate(-240,0)" />
</g>
</defs>
<!-- ----------------------------------------
Here is the question:
the first use element is not displayed.
The second one is displayed. (the elements are under this text)
Why does it not work?
How can a use element be used within nested g elements?
(to test it you can comment out the second use element,
even tough both use elements have the same attributes
no icon is visible anymore)
---------------------------------------- -->
<!-- following does not work: -->
<g id="testg">
<use xlink:href="#icon2" x="100" y="50" />
</g>
<!-- following works: -->
<use xlink:href="#icon2" x="100" y="50" />
<!-- why???? -->
It does work. Your jsfiddle is not the same as your inline code (the x and y of the use are not the same).
If you make the x and y values in the <g> the same as outside it will work. In the non-working case you are clipping out the contents of the <use> with your clip-path.
You can't see it because they are superposed... =)

I have a zoomable svg that's provided by 3rd a party API. It's basically a drawing that's mapped to a grid. The problem is the API doesn't include the grid in the provided svg file so I have to hack it to include one. Basically, the markup is like this:
<svg>
<g>
<line>....
<rect>....
etc...
</g>
</svg>
The zoom functionality is done and now I'd like to add the grid. I'm thinking I should add it like so:
<svg>
<g>
<rect x="0" y="0" width="100%" height="100%" fill="black" />
<defs>
<pattern id="grid" width="20" height="20" patternUnits="userSpaceOnUse">
<path d="M 1 1 L 0 0 0 0" fill="none" stroke="green" stroke-width="1" />
</pattern>
</defs>
<rect x="-100%" y="-100%" width="200%" height="200%" fill="url(#grid)" />
<line>....
<rect>....
etc...
</g>
</svg>
The grid is drawn but it's bound within the <g> tag. Is it possible to extend the grid beyond it but still zoomable? Or are there other better ways to achieve this?
