In this article a scrollbar gets a new look. There is a line in the style which appears to put the triangle in the scroll buttons. I don't know how to read it though.
Content="M 0 0 L 4 4 L 8 0 Z"/>
What does that mean in the context of the control?
It's just the geometry for the Path Data. If you'd like to reproduce it just do something like <Path Data="YourPath"/>
Hope this helps.

Is there some kind of a wrapper object in SVG that I can use to shift all objects (lines, polygons, circles, text etc) down and to the right in a simple easy fashion? I realize now that I have not left enough space in the top left corner of my SVG definition.
Maybe there is a margin or padding element in SVG that I can use. Please note that I do not desire to wrap this inside HTML or use CSS trickery to achieve this, but ideally I would like to do this with pure SVG if possible.
You can either alter the viewBox attribute to reveal different portion of the infinite plane, i.e. changing e.g.
<svg viewBox="0 0 100 100">
to
<svg viewBox="-10 -10 110 110">
will bring extra 10 point rows and columns to top an left, effectively shifting content to bottom right (and shrinking it).
Or you can wrap all root elements of your SVG into <g> element and apply (add) single transform to all its children through it:
<g transform="translate(10, 10)">
<!-- content -->
</g>
I have an SVG path that I'm trying to dynamically create, but the resources I've found on SVG paths don't describe that path I have.
This is the path:
m41.5 1.5v15l-40 10v100h60v-100l-10-10v-15z
I don't even understand the start of it - the m41.6; m moves the pen to a coordinate relative to the last known position. I assume this is the origin? but everywhere I've found says that the syntax is m x,y. If I supply m41.6,0 instead, the svg just disappears - opening in Inkscape doesn't show it either.
I need a step-by-step explanation please of each term.
The full SVG is:
<svg id="svg11" version="1.1" viewBox="0 0 63 128" xmlns="http://www.w3.org/2000/svg">
<path d="m41.5 1.5v15l-40 10v100h60v-100l-10-10v-15z" fill="#ffd42a"/>
</svg>
the resources I've found on SVG paths don't describe that path I have.
Then I guess you didn't consider reading the SVG specification? :)
Try reading the Paths section of the SVG specification . It's all explained quite clearly there.
Explanation
m41.5 1.5
Move to (41.5, 1.5). m is a relative move normally, but the spec says:
If a relative moveto (m) appears as the first element of the path, then it is treated as a pair of absolute coordinates.
Coordinates can be separated by a comma, whitespace, both, or even neither. For example, M1.5.5 is a valid path command, since a coord can't have more than one decimal point, and leading zeros are optional.
M 1.5,0.5, M1.5 0.5, M1.5, 0.5, M 1.5 .5, and M1.5.5 are all equivalent.
v15
Draw a line vertically (downward) by 15 units
l-40 10
Draw a line left by 40 and down by 10 units.
v100
Draw a line down by 100 units
h60
Draw a line right by 60 units
v-100
Draw a line upwards by 100 units
l-10-10
Draw a line diagonally up and left by (10,10)
v-15
Draw a line vertically upwards by 15 units
z
Close the path (ie back to 41.5,1.5)
The path can be rewritten as:
m41.5,1.5 v15 l-40,10 v100 h60 v-100 l-10,-10 v-15 z
or
m41.5 1.5 v15 l-40 10 v100 h60 v-100 l-10 -10 v-15 z
This better separates the individual pen movements which I was confused by when they were all merged together in the original version.
I am working on someone else's code and there's no way of contacting them, and here's my issue:
<g
ng-attr-transform="translate({{node.width-18}}, 0) scale(0.6)"
ng-mouseover="showArrowMenuTooltip($event, node);"
ng-click="showArrowMenuTooltip($event, node);"
ng-mouseleave="hideArrowMenuTooltip($event);"
ng-attr-class="{{'flowchart-arrow-show-'+node.activity.act_task +' flowchart-arrow-set'}}">
<!--Circle-->
<path
class="flowchart-arrow-circle"
d="M16,1.466C7.973,1.466,1.466,7.973,1.466,16c0,8.027,6.507,14.534,14.534,14.534c8.027,0,14.534-6.507,14.534-14.534C30.534,7.973,24.027,1.466,16,1.466z"
></path>
<!--Arrow-->
<path
class="flowchart-arrow"
d="M13.665,25.725l-3.536-3.539l6.187-6.187l-6.187-6.187l3.536-3.536l9.724,9.723L13.665,25.725z"
></path>
</g>
That's some code inside an SVG tag that draws an arrow with a circle around it, my question is, suppose I want to draw an explanation mark, how would I do that?
I'm sure the d="M13... part is not written manually, yet i can't find online any documentation or tool that would help.
What you're after is called a 'Path' element.
Check this documentation out:
https://www.w3.org/TR/SVG/paths.html#PathData
A path is defined by including a ‘path’ element which contains a
d="(path data)" attribute, where the ‘d’ attribute contains the
moveto, line, curve (both cubic and quadratic Béziers), arc and
closepath instructions.
Example triangle01 specifies a path in the shape of a triangle. (The M
indicates a moveto, the Ls indicate linetos, and the z indicates a
closepath).
Good morning,
I've created a chord diagram using D3. But I've encountered a problem with the output that causes paths to be rendered poorly in some versions of Chrome.
Here's an example of a problematic path generated by D3:
<svg height="1000px" width="1000px">
<g transform="translate(400,400)">
<path d="M329.2336690603744,-46.49130195040491A332.5,332.5 0 0,1 329.2336694247276,-46.491299370194035Q 0,0 -25.421977592957564,-331.5267305290222A332.5,332.5 0 0,1 -25.42197499477598,-331.5267307282548Q 0,0 329.2336690603744,-46.49130195040491Z" class="chord" fill="#c8cfdc" stroke-width="1px" stroke="#000000"></path>
</g>
</svg>
In most browsers, I see a single arc, which is what I'd expect. But on my dev machine running Chrome version 36.0.1985.125 on Ubuntu 14.04 I see the arc on top of a big gray circle. The big circle kind of ruins the rest of the diagram.
Is there anything particularly problematic about this path's d attribute that could cause it to get painted inconsistently by the browser?
Many thanks.
Here's an image of what I'm seeing when it goes wrong:
Expanding on #jshanley's comment, the breakdown of the path data is as follows (long decimals trimmed for readability):
d="M 329,-46
//Move the pen to the starting point (329,-46)
A 332.5,332.5 0 0,1 329,-46
//draw a circular arc (radius in both directions 332.5 with 0 degrees rotation),
//in a clockwise direction taking the shortest route (flags 0,1)
//ending at point (329,-46).
//In a normal chord diagram, this is the edge of the chord, which follows the
//arc of the large circle.
//However, in this case the start and end points are the same
//and nothing should be drawn
Q 0,0 -25,-331
//draw a quadratic curve to point (-25, -331) using control point (0,0)
//this is the curve you see, connecting different points on the large circle
A 332.5,332.5 0 0,1 -25,-331
//another arc with the same start and end points, which shouldn't be drawn
Q 0,0 329,-46
//Another quadratic curve, the exact same shape as the previous one
//but going back in the opposite direction;
//this is what causes the curve to look like a single line, no fill
Z"
//close the shape
This is a definite bug in the Ubuntu Chrome version you're using. Path arc segments that start and end at the same point are supposed to be skipped, regardless of what the flag settings are, because they are not clearly defined. Even if the browser wasn't automatically skipping it, you'd think they would still respect the "short arc" flag and draw a zero-length arc.
If support for that particular browser version is important, you'll need to add in an error-check in your code, so that you don't draw the chords at all when they have zero width on both ends, or manually edit the path data to remove the empty arc commands.
The following path draws an arc in ie 8 + and firefox. But in vml i cant able to draw the arc. Is there any way to draw the arc in vml without using raphael.
d="M 400 315 A 26 26 0 0 1 423 400 L 400 342 z"
Thanks in advance
The path posted seems like a SVG path. Similarly one can also provide paths to draw sahpes in VML. Try reading this: http://www.w3.org/TR/NOTE-VML.
ex: A sample VML path for an arc would be similar to this: path="m21600,qx,10800,21600,21600xe" But one would also have to define formulas for the rendering application to interpret it. again I would suggest to read the above link to understand VML formulas.
