I tried doing a height animation so the bars from my diagram go from 100% height to 30% and then back to 100%. I thought i could just do it with the attribute "height" but apparently not. Its not working at all and not doing anything so obviously i did do something wrong. I am not sure what to use instead.

</svg>I then tried it with scale but the rectangles move way down and look just wrong. I mean somehow its kinda working but its not from use when its going further down than where the diagram ends.
I appreciate any help :))

</svg><path> elements don't have a height property/attribute.
As commented by Michael Mullany you're better off rebuilding the graphs manually in SVG code. Just because graphic applications tend to export rather convoluted SVG markup that's hard to manipulate when coding something like animations.
As always, it depends on your requirements – check out the candidates:
<path>: doesn't have a height property. You can animate its geometry or pathData (represented by d attribute) both in SMIL (so via SVG animate attribute) or via CSS d property. For the latter – unfortunately, the d property is to this date not supported by webkit browsers (most notably Apple's Safari). Although, animating the path data by SMIL works in all browsers – it's also not very convenient as it requires a quite profound understanding of path data commands (e.g all "morphed" command need to be compatible)<line> would allow you to animate the starting or end coordinates of a line – represented by y1 and y2 attributes. Drawbacks: 1. not accessible via CSS 2. you can only apply a uniform corner-rounding-radius via stroke-line-cap. A valid candidate for non-rounded elements but not suitable in your case.<rect>: provides a height property as well as a border-radius attribute by rx and ry attributes (even stylable via CSS ... except in webkit/Safari). Bingo??? There's still a little catch. While we can reliably animate the height attribute/property – we can't directly define a "height-change-origin". However we can solve this with transforms:<svg viewBox="0 0 100 100">
<style>
.rect {
fill: #ccc;
/* flip graphs */
transform: scale(1, -1);
/* define axis origin as transforms-origin referance point */
transform-origin: 0 80px;
width: 10px;
animation: 1s graphAni forwards alternate infinite ease-in-out;
}
.delay0 {
animation-delay: 0.25s;
}
.delay1 {
animation-delay: 0.5s;
}
.delay2 {
animation-delay: 0.75s;
}
.delay3 {
animation-delay: 1s;
}
@keyframes graphAni {
to {
height: 0px;
}
}
</style>
<!-- x/y axis -->
<path d="M 17.5 20 v60 h65" stroke="#ccc" stroke-width="5" stroke-linecap="round" stroke-linejoin="round" fill="none" />
<!-- graphs -->
<rect class="rect delay0" x="25" y="80" rx="2.5" height="20" />
<rect class="rect delay1" x="40" y="80" rx="2.5" height="30" />
<rect class="rect delay2" x="55" y="80" rx="2.5" height="40" />
<rect class="rect delay3" x="70" y="80" rx="2.5" height="50" />
</svg>Basically, we just flip the graph rendering via transform: scale(1, -1) so we can increase/decrease the height value during animation. We also need to set a transform origin as a reference point – which would be the graph axis origin.
Here's an example how it looks without transformations:
svg {
width: 50vmin;
display: block;
outline: 1px solid #ccc;
overflow: visible;
}<svg viewBox="0 0 100 100">
<style>
.rect {
fill: red;
/* define axis origin as transforms-origin referance point */
transform-origin: 0 80px;
width: 10px;
animation: 1s graphAni forwards alternate infinite ease-in-out;
}
.delay0 {
animation-delay: 0.25s;
}
.delay1 {
animation-delay: 0.5s;
}
.delay2 {
animation-delay: 0.75s;
}
.delay3 {
animation-delay: 1s;
}
@keyframes graphAni {
to {
height: 0px;
}
}
</style>
<!-- x/y axis -->
<path d="M 17.5 20 v60 h65" stroke="#ccc" stroke-width="5" stroke-linecap="round" stroke-linejoin="round" fill="none" />
<!-- graphs -->
<rect class="rect delay0" x="25" y="80" rx="2.5" height="20" />
<rect class="rect delay1" x="40" y="80" rx="2.5" height="30" />
<rect class="rect delay2" x="55" y="80" rx="2.5" height="40" />
<rect class="rect delay3" x="70" y="80" rx="2.5" height="50" />
</svg>Also, we may not need different initial height values but instead rely on animation delays to get a "stepped" graph rendering.
