Reverse radialGradient SVG animation on mouseout on hovered element

I want the radialGradient animation to apply to the single hexagon only that you are hovering over and then onmouseout I want the animation to reverse.
How can I make the radialGradient trigger on the hexagon you hover on only (not all the hexagons) and then reverse the animation on mouseout/mouseleave? Thank you.
I tried adding
{ fill: url(#myRadialGradient4);}
to
.filter-class
But obviously as soon as mouseout happens the class is removed stopping the smooth reverse animation on mouseout.
I have tried this:
https://codepen.io/daneli84/pen/OJVZmeJ
//
var flagBlur = document.querySelector('.flag-blur');
var flags = document.querySelectorAll('.flag');
//
function startPage() {
flags.forEach(flag => {
flag.onmouseover = function() {
flag.classList.add('filter-class')
TweenMax.fromTo(flagBlur, 19, {
attr: {
stdDeviation: 0.5
}
}, {
attr: {
stdDeviation: 1
},
ease: Power1.easeInOut
});
}
flag.onmouseleave = function() {
flag.classList.remove('filter-class')
}
})
}
startPage();

The radial gradient you are animating would need to be a separate one from the one you are using for the rest of the hexagons.
On hover you would switch to the alternate gradient and start the <animation> by calling beginElement() on it. You might also need a third <animation> for the reverse animation.
But that approach is complicated, and I don't think it would produce a very satisfactory result.
A different approach
I would recommend a different approach.
Make the background of each hexagon a rectangle that has the gradient applied to it
then animate that background on hover
use a hexagon shaped clipping path on that rect
You can do that with pure CSS. And it is a lot simpler.
Note: in the example below I've stripped out the filter to make things simpler to follow for this example.
.pod-bg {
-webkit-transition: 5s;
-webkit-transition: all 5s ease;
transition: all 5s ease;
}
.pod-bg:hover {
transform: translate(0, -16px);
}
.h1.flag {
fill: url(#myRadialGradient4);
}
.pod-stroke {
stroke: #000000;
stroke-width: 0.1;
fill: none;
pointer-events: none;
cursor: pointer;
}
text {
pointer-events: none;
color: white;
}

Fade color in path tag

In HTML with SVG you can create a rect with fading color:
<svg>
<rect width="100%" height="100%">
<animate attributeName="fill" values="red;blue;red" dur="10s" repeatCount="indefinite" />
</rect>
</svg>
Now in my code I have a path like that:
<svg xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink" width="247pt" height="543pt" viewBox="0.00 0.00 246.86 543.19">
<g id="graph0" class="graph" transform="scale(1 1) rotate(0) translate(4 539.1859)">
<!-- c->e -->
<g id="a1124" class="edge">
<title>c->e</title>
<path fill="none" stroke="#ff0000" stroke-width="3" d="M208.109,-297.8625C205.1217,-279.2357 200.2512,-248.8658 195.5911,-219.8076" />
<polygon fill="#ff0000" stroke="#ff0000" stroke-width="3" points="198.9943,-218.9251 193.9549,-209.6055 192.0827,-220.0336 198.9943,-218.9251" />
</g>
</g>
</svg>
I am looking for a way to fade the color of the path along the path so that it illustrates some kind of data flow. Is there a way to accomplish that? (via CSS or Javascript).

Try this
#keyframes fade {
0% {
stroke: red;
fill: red;
}
50% {
stroke: blue;
fill: blue;
}
100% {
stroke: red;
fill: red;
}
}
#fade {
animation-name: fade;
animation-duration: 10s;
animation-iteration-count: infinite;
}

Google Visualization Pie Chart - changing text coordinates

I have made a simple donut chart (based on the Google Visualization example at https://google-developers.appspot.com/chart/interactive/docs/gallery/piechart#donut).
As it only shows one slice (the other is transparent/invisible), I'd like to move the <text> element to the centre of the chart, i.e., within the hole. I know that it simply involves updating the 'x' and 'y' coordinate attributes but I'm having trouble accessing them in the DOM, particularly as there are no IDs/classes to hang onto.
So, how can I target the <text> element of the penultimate <g> element in this code? I'd like to change x="239.45622566746957" y="285.69328724429994" to x="200" y="200"
Javascript preferred but jQuery also fine...

Use a selector like this:
document.querySelector('#donutchart svg > g:nth-last-child(2) text');
This will not work in IE8, as older versions of IE do not support SVG. If you need to support IE8, you will need a selector for the equivalent VML structure.

How to change the css style for Google charts

In rails 3.2.13 project, I am using google charts for reports, but graph is not aligned properly.
Graph should be in responsive format(not fixed format). Now Height & Width of this chart is in 'px' format, I need to change in '%' format. How can I change CSS style for google chart?
I am using below gem for charts
gem 'reporter', '0.0.14.alpha' , :git => "https://github.com/kpvarma/reporter.git"
In views, outer div container contains 100% width
<div id="<%= container_id %>" style="float:left;width: 100%;"></div>

I'm not sure if the below would be helping in your conversion but the standard conversion is as below.
1em = 12pt = 16px = 100%.
It can be found at this link
please update if this is helpful. Also you can refer Converting width from percentage to pixels for similar question.
Also there is a calculator online found here, where in you give the pixel-width and you get in percentage.
Happy Coding :-)
