线图的SVG缩放

Question

I would like to have a responsive SVG for a line chart. This should have three areas that combine fixed and scalable elements.

The pink element should be a scaling child svg (I need to define a child coordinate system for drawing a polyline), the grey bits are used for drawing axis, and should have limited scaling, since text should render in a relativaly simple font.

Finally, I would like to do this without JavaScript.

Some of the problems I have faced and which might help with a solution:

1. If I could give the <svg> element that is the pink area the following x="20px" width="calc(100% - 20px)" height="calc(100% - 20px)" , this would largely solve my problem, but this triggers a parse error. I haven't managed to get any variations using CSS to work either.

Answer 1

(Another answer would be well worth it if someone can do this with "pure" svg).

I hacked it using HTML layout and multiple SVGs. This is the code I am using:

 <div style="width: 100%; height: 300px"> <!-- The Y axis --> <svg style="width: 40px; height: calc(100% - 20px); float: left;"> <g class="yaxis"> <line x1="99%" x2="99%" y1="0%" y2="100%" stroke="black" vector-effect="non-scaling-stroke"></line> <g class="tick tick-yaxis"> <text x="99%" y="100%" text-anchor="end">$0.0</text> <line x1="98%" x2="100%" y1="100%" y2="100%" stroke="black"></line> </g> <!-- ... --> </g> </g> </svg> <!-- The actual chart --> <svg viewBox="0 0 100 100" preserveAspectRatio="none" style="width: calc(100% - 40px); height: calc(100% - 20px); float: left;"> <polyline points="0,50 45.46574414322495,0 65,100 75,100 89.52839708894965,0 91.10141646672459,100 98.21939424857649,0 100,100" vector-effect="non-scaling-stroke" stroke="red" fill="none"></polyline> </svg> <!-- x axis --> <svg style="clear: both; margin-left: 40px; width: calc(100% - 40px); height: 20px;"> <g class="xaxis"> <line x1="0%" x2="100%" y1="1%" y2="1%" stroke="black" vector-effect="non-scaling-stroke"></line> <g class="tick tick-xaxis"> <text x="5%" y="100%" text-anchor="middle">28 Feb 2011</text> <line x1="5%" x2="5%" y1="94%" y2="96%" stroke="black"></line> </g> </svg> </div>
