I read the tutorial about gradients in SVG at http://www.svgbasics.com/text2.html. I was impressed by the Text fill and stroking part. It used a gradient defined to display text in a shaded manner. I was just wondering, can I change the size of the text using this gradient. Please give me an example of how to do this in a single tspan element.
You can style the tspan elements with CSS, if you want to change the font-size that can be done e.g like this:
<style>
tspan { font-size: 48px }
</style>
or alternatively using the corresponding presentation attribute:
<text>...<tspan font-size="48">big text</tspan>...</text>

I use jvectormap. I create map. I need to save this svg map as image. I use a plugin named saveSvgAsPng.js. It works ok. My problem is that ,png image makes transparent. Is there a method that I remove svg background transparency?
Thanks in advance.
Have you tried looking at the usage Docs for saveSvgAsPng ?
https://github.com/exupero/saveSvgAsPng
saveSvgAsPng(document.getElementById("diagram"), "diagram.png", {backgroundColor: "white"});
Try and pass "white" or the HEX color value "#FFFFFF"
Pass backgroundColor in the options object:
Available Options:
backgroundColor — Creates a PNG with the given background color. Defaults to transparent.
scale — Changes the resolution of the output PNG. Defaults to 1, the same dimensions as the source SVG.
selectorRemap — A function that takes a CSS selector and produces its replacement in the CSS that's inlined into the SVG. Useful if your SVG style selectors are scoped by ancestor elements in your HTML document.
I'm working on a visualisation involving stacked histogram with really thin bars.
The problem is that white background introduces unpleasant visual vibration and make bars somewhat hard to interpret:

What I'm looking for is a way to set a specific colour for chart background. I've tried to set it for SVG element like so:
svg {
background-color: #ccc;
}
But (obviously) it doesn't work properly:

How do I set a background colour so that it'll be exactly the same shape as a chart?
I managed to come to this quick-and-dirty solution. Just adding a one pixel pseudo-shadow to the right of each bar:
rect {
-webkit-svg-shadow: 1px 0px #ccc;
}
Produces this:

How is the chart being instantiated? by using svg { background-color: #ccc;} you are setting the background color of all svg elements to #ccc (except where over-ridden), so if your chart is a child of another svg element with some margins it would explain why the alignment is no good.
One strategy to go about fixing may be to use your browser's debugging abilities (ctrl+shift+i to bring up 'developer tools' in chrome) to take a look at the DOM elements and try to narrow down which ones cover which areas of the graph vs the areas of the graph plus the margins on the bottom/left. not sure about other browsers but chrome is useful in that if you hover over an element in the html document it will 'highlight' that element in the browser. This might help you narrow down which objects specifically need to be stylized.
I am applying a border radius on a select element that has a background color.
Instead of following the curvers of the border, the background color overlaps the curves and appears in a square box.
I can't figure out what css property I must use to solve this issue.
background-color: #FF0;
border-radius: 24px;
border: 4px solid #F09;
Here is the jsfiddle: http://jsfiddle.net/JsgnR/
thanks for your help
My feeling about this is, to get this to work in every common browser, you will have to rebuild the select with JS ... unfortuneatly styling selects with css like a divbox still not is possible as you would expect. In latest Firefox your code looks nice in browser, because firefox decided to let the border overlap the select, in latest opera the border will be underneath the select, because they decided to.
you see that on the options , try to style them via css, you are not able and they look ugly
You can wrap <select> element in <span></span> and add the required properties to css for

i want to acheive the effect on this page using SVG. As you can see it uses a series of PNG transparent overlays when the user mouses over a polygonal hotspot drawn on a product.
What i want to achieve is the same thing with SVG, but without messing about with creating a load of PNGs, so that when the user mouses over an area the transparent shape (with link on it) appears over the top. The SVG shape would be built from a set of coordinates exactly as a polygonal hotspot would on an image map.
So i guess my first question is, can this be done with plain old SVG or do i need to use something like Raphael to achieve this? Never seen this effect before with SVG so if anyone has an example like that would be very useful.
Thanks in advance.
There are several ways to get this effect with plain old SVG. Probably the simplest is to use CSS within the SVG. For example:
<style>
.overlay:hover
{
opacity: 0.5;
}
</style>
<svg>
<a xlink:href="http://www.wherever/you/want/to/link/to.com">
<path class="overlay" d="Coordinates of your shape..." />
</a>
</svg>
I've written about various other methods at:
http://www.petercollingridge.co.uk/data-visualisation/mouseover-effects-svgs
Yes it can be done with SVG only, with or without javascript.
One way to get the effect would be to overlay a white semi-transparent path on top of the image that you want to whiten. Another way would be to use an SVG filter to process the image directly, similar to what I've done here or here to recolor a PNG (view page source and feel free to reuse that in any way you like).
You'll want to make use of the 'pointer-events' property most likely. Here's an example showing how to detect mouse-events on the fill and/or stroke of an svg shape, even if the shape is invisible.
Having some trouble with the CSS alignment of text generated with #font-face. For some reason, there is a ton of extra space visible at the bottom of each letter, stretching the text's containing box too far downward.
If you inspect the text on this sample page, you can see what I mean.
Have googled and inspected a bunch of other pages, but this one's got me stumped. Any chance someone could help?
Thanks!
For starters, the computed line-height is 65px, so you could always define it to be 60px if you wanted.
However, most of that space is actually just required by the font you chose. Though you've converted it to uppercase with your CSS, the font still needs room to render characters that draw below the text's baseline. Try adding a comma to that header's text, and you'll see it's actually pretty huge and should fill up most of the empty space.
You are using <h2> tag there.
for the h tags use the CSS style's margin and padding to remove those extra spaces.
<style>
h2 {
margin:0;
padding:0;
}
</style>
