I am trying to make a plot with each data point labelled on the x-axis with a text string written vertically. It all seems to work as expected except that the labels appear to be shifted left by one unit. I thought it was a bug in my c++ generating code but finally made a test case. In the following, I wanted the red and blue lines to underline the text but they
seem to go through the text. The green lines, offset by one, appear where
I thought the others should be relative to the text. What do I need to do here? The center of rotation does appear as expected. Thanks. Right now I'm just kluging the code to fix the offset but would like to fix it lol.

I want to reverse the word compared to the line without having to redraw the line, how to do?
/Ps: when I use transform="scale(-1,1)" it doesn't work because the line path is inverted.
You could use <textPath side="..."> for that. However, it's only supported by Firefox right now.
<svg viewBox="0 0 100 55" xmlns="http://www.w3.org/2000/svg">
<path id="curve" fill="none" stroke="limegreen" stroke-width="1" d="M10,5 c20,60 50,50 80,10"></path>
<text font-size="5" dy="-1">
<textPath href="#curve" startOffset="6" side="left">Dangerous curves ahead</textPath>
</text>
<text font-size="5" dy="-1">
<textPath href="#curve" startOffset="9" side="right">Dangerous curves ahead</textPath>
</text>
</svg>
If this is what you have:
body{background:white;}
<svg width="250" height="200" viewBox="0 0 250 200">
<defs>
<path id="thePath" d="M55,100 a70,40 0 1 0 0,-1 z" stroke="#FF0000" fill="transparent" stroke-width="1" ></path>
</defs>
<use xlink:href="#thePath"></use>
<text stroke="#000000" font-size="20">
<textPath xlink:href="#thePath" startOffset="7%">
Some text here
</textPath>
</text>
</svg>
You can apply a transformation transform="scale(-1,1) translate(-250,0)" to the path like so:
body{background:white;}
<svg width="250" height="200" viewBox="0 0 250 200">
<defs>
<path id="thePath" d="M55,100 a70,40 0 1 0 0,-1 z" stroke="#FF0000" fill="transparent" stroke-width="1" transform="scale(-1,1) translate(-250,0)"></path>
</defs>
<use xlink:href="#thePath"></use>
<text stroke="#000000" font-size="20">
<textPath xlink:href="#thePath" startOffset="7%">
Some text here
</textPath>
</text>
</svg>
I hope this is what you need

Markers have a rectangular clipping area at the bounds of their tile. That's 0,0 to 385, 359 in your case so you need to draw the marker within that rect.
A circle with a cy="5" and r="13" will render above the y axis and therefore outside the clipping rect.
We can simply translate the marker contents and then move the marker refY to compensate. I've set the markerWidth and markerHeight at more sensible values too as having them too large prevents the browser from optimising marker rendering.

How can I make my clipping masks work?
I have 4 paths positioned at 0,0. I translate them and scale them so they are positioned at the same position as the referenced clipping mask.
Thanks!

The problem is that the translate and scale is also applied to the clip-path when the translate and scale is applied to an element. If you adjust the x/y/width/height on the clip path definition to something like 0.2/0.2/0.5/0.5 then you'll see the clip-path take effect.
You may want to express your clip path using %'s by specifying clipPathUnits="objectBoundingBox" in your clipPath element. That way, you may only need one clipPath definition.
I want to color the background of svg text similar to background-color in css
I was only able to find documentation on fill, which colors the text itself
Is it even possible?
You could use a filter to generate the background.
<svg width="100%" height="100%">
<defs>
<filter x="0" y="0" width="1" height="1" id="solid">
<feFlood flood-color="yellow" result="bg" />
<feMerge>
<feMergeNode in="bg"/>
<feMergeNode in="SourceGraphic"/>
</feMerge>
</filter>
</defs>
<text filter="url(#solid)" x="20" y="50" font-size="50">solid background</text>
</svg>
No this is not possible, SVG elements do not have background-... presentation attributes.
To simulate this effect you could draw a rectangle behind the text attribute with fill="green" or something similar (filters). Using JavaScript you could do the following:
var ctx = document.getElementById("the-svg"),
textElm = ctx.getElementById("the-text"),
SVGRect = textElm.getBBox();
var rect = document.createElementNS("http://www.w3.org/2000/svg", "rect");
rect.setAttribute("x", SVGRect.x);
rect.setAttribute("y", SVGRect.y);
rect.setAttribute("width", SVGRect.width);
rect.setAttribute("height", SVGRect.height);
rect.setAttribute("fill", "yellow");
ctx.insertBefore(rect, textElm);
The solution I have used is:
<svg>
<line x1="100" y1="100" x2="500" y2="100" style="stroke:black; stroke-width: 2"/>
<text x="150" y="105" style="stroke:white; stroke-width:0.6em">Hello World!</text>
<text x="150" y="105" style="fill:black">Hello World!</text>
</svg>
A duplicate text item is being placed, with stroke and stroke-width attributes. The stroke should match the background colour, and the stroke-width should be just big enough to create a "splodge" on which to write the actual text.
A bit of a hack and there are potential issues, but works for me!
Instead of using a <text> tag, the <foreignObject> tag can be used, which allows for XHTML content with CSS.
No, you can not add background color to SVG elements. You can do it programmatically with d3.
var text = d3.select("text");
var bbox = text.node().getBBox();
var padding = 2;
var rect = self.svg.insert("rect", "text")
.attr("x", bbox.x - padding)
.attr("y", bbox.y - padding)
.attr("width", bbox.width + (padding*2))
.attr("height", bbox.height + (padding*2))
.style("fill", "red");
Answer by Robert Longson (#RobertLongson) with modifications:
<svg width="100%" height="100%">
<defs>
<filter x="0" y="0" width="1" height="1" id="solid">
<feFlood flood-color="yellow"/>
<feComposite in="SourceGraphic" operator="xor"/>
</filter>
</defs>
<text filter="url(#solid)" x="20" y="50" font-size="50"> solid background </text>
<text x="20" y="50" font-size="50">solid background</text>
</svg>
and we have no bluring and no heavy "getBBox" :)
Padding is provided by white spaces in text-element with filter.
It's worked for me
Going further with #dbarton_uk answer, to avoid duplicating text you can use paint-order=stroke style:
<svg>
<line x1="100" y1="100" x2="350" y2="100" style="stroke:grey; stroke-width: 100"/>
<text x="150" y="105" style="stroke:white; stroke-width:0.5em; fill:black; paint-order:stroke; stroke-linejoin:round">Hello World!</text>
</svg>
Note the stroke-linejoin:round which is needed to avoid seeing spikes for the W sharp angle.
You can combine filter with the text.

<text fill="black" x="20" y="50" font-size="30">text with color</text>
</svg>

</html>
this is my favorite hack (not sure it should work). It refer an element that is not yet displayed, and it works pretty well
<svg version="1.1" xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink" viewBox="0 0 620 40" preserveAspectRatio="xMidYMid meet">
<defs>
<filter x="-0.02" y="0" width="1.04" height="1.1" id="removebackground">
<feFlood flood-color="#00ffff"/>
</filter>
</defs>
<!--Draw the text-->
<use xlink:href="#mygroup" filter="url(#removebackground)" />
<g id="mygroup">
<text id="text1" x="9" y="20" style="text-anchor:start;font-size:14px;">custom text with background</text>
<line x1="200" y1="18" x2="200" y2="36" stroke="#000" stroke-width="5"/>
<line x1="120" y1="27" x2="203" y2="27" stroke="#000" stroke-width="5"/>
</g>
</svg>
For those wondering how to apply padding to a text element when it has a background like in the Robert's answer, do the following:
<svg>
<defs>
<filter x="-0.1" y="-0.1" width="1.2" height="1.2" id="solid">
<feFlood flood-color="#171717"/>
<feComposite in="SourceGraphic" operator="xor" />
</filter>
</defs>
<text filter="url(#solid)" x="20" y="50" font-size="50">Hello</text>
</svg>
In the example above, filter's x and y positions can be used as transform: translate(-10%, -10%) would, and width and height values can be read as 120% and 120%. So we made background 20% bigger, and offsetted it -10%, so background is now 10% bigger on each side of the text.
The previous answers relied on doubling up text and lacked sufficient whitespace.
By using atop and I was able to get the results I wanted.
This example also includes arrows, a common use case for SVG text labels:

An obvious workaround to the problem of the blur produced by the filter effect is to render the <text> two times: once for the background (with transparent characters) and once for the characters (without a background filter).
For me, this was the only way to make the text readable in Safari.
<svg width="100%" height="100%">
<filter x="0" y="0" width="1" height="1" id="solid">
<feFlood flood-color="yellow" />
</filter>
<g transform="translate(20, 50)" font-size="50">
<text aria-hidden="true" fill="none" filter="url(#solid)">solid background</text>
<text fill="blue">solid background</text>
</g>
</svg>
The aria-hidden="true" attribute is there to prevent screen readers from speaking the text twice, if the user uses a screen reader.
You can add style to your text:
style="-webkit-tap-highlight-color: rgba(0, 0, 0, 0);
text-shadow: rgb(255, 255, 255) -2px -2px 0px, rgb(255, 255, 255) -2px 2px 0px,
rgb(255, 255, 255) 2px -2px 0px, rgb(255, 255, 255) 2px 2px 0px;"
White, in this example.
Does not work in IE :)
I want to hide anything that outside a rectangle. (this i have achieved with clipping successfully). but another condition is that, 'also hide anything that comes inside the black big circle'. Now how i can achieve that?
in below example, 'yellow circle' must be eliminated'.
see below images for detail

Below is my Svg code:-
<svg xmlns="http://www.w3.org/2000/svg" version="1.1" width="500" height="500">
<g>
<rect x="50" y="50" width="200" height="200" stroke="1" fill="red"/>
<circle cx="180" cy="150" r="30" stroke="blue" />
</g>
<g clip-path = "url(#clip1)">
<circle cx="180" cy="150" r="10" stroke="blue" fill="yellow" />
</g>
<clipPath id = "clip1">
<rect x="50" y="50" width="200" height="200" stroke="1" fill="red"/>
</clipPath>
</svg>
Erik Dahlström is right, your clip can include the entire rectangle and the cutout for the circle. This way, anything you associate with #clip1 as the clip-path will not be visible inside your circle area. Here is what it looks like for your example:
<svg xmlns="http://www.w3.org/2000/svg" version="1.1" width="500" height="500">
<g>
<rect x="50" y="50" width="200" height="200" stroke="1" fill="red"/>
<circle cx="180" cy="150" r="30" stroke="blue" />
</g>
<g clip-path = "url(#clip1)">
<circle cx="180" cy="150" r="10" stroke="blue" fill="yellow" />
</g>
<clipPath id = "clip1">
<path d="M 50,50 l200 0 l0 200 l-200 0z M150,150 a30,30 1 0,0 60,0z M210,150 a30,30 1 0,0 -60,0z"/>
</clipPath>
