And now a Blogger can do the same by using following easy steps.
See the Demo of Label or Tag Cloud Widget
At least one of your labels has more than one entry. A bug in the script causes it to fail when all the labels have only one entry.Also, make sure that none of your labels contain quote marks " .
1. Login to Blogger >> Layout >> Page Elements >> Add a Gadget >> Labels. A new window will open. Sorting should be Alphabetically and now hit SAVE. Now go to Edit HTML. Download Full Template for backup.
2. Now look for this tag
]]></b:skin>
And place following code before that tag.
/* Label Cloud Styles
----------------------------------------------- */
#labelCloud {text-align:center;font-family:arial,sans-serif;}
#labelCloud .label-cloud li{display:inline;background-image:none !important;padding:0 5px;margin:0;vertical-align:baseline !important;border:0 !important;}
#labelCloud ul{list-style-type:none;margin:0 auto;padding:0;}
#labelCloud a img{border:0;display:inline;margin:0 0 0 3px;padding:0}
#labelCloud a{text-decoration:none}
#labelCloud a:hover{text-decoration:underline}
#labelCloud li a{}
#labelCloud .label-cloud {}
#labelCloud .label-count {padding-left:0.2em;font-size:9px;color:#000}
#labelCloud .label-cloud li:before{content:"" !important}
3. Now add following code After
]]></b:skin>
and before </head> tag.
<script type='text/javascript'>
// Label Cloud User Variables
var cloudMin = 1;
var maxFontSize = 20;
var maxColor = [0,0,255];
var minFontSize = 10;
var minColor = [0,0,0];
var lcShowCount = false;
</script>
Above code is the variable section.
4. Now look for following
<b:widget id='Label1' locked='false' title='Labels' type='Label'/>
Now copy the following code and replace it with above line.
<b:widget id='Label1' locked='false' title='Label Cloud' type='Label'>
<b:includable id='main'>
<b:if cond='data:title'>
<h2><data:title/></h2>
</b:if>
<div class='widget-content'>
<div id='labelCloud'/>
<script type='text/javascript'>
// Don't change anything past this point -----------------
// Cloud function s() ripped from del.icio.us
function s(a,b,i,x){
if(a>b){
var m=(a-b)/Math.log(x),v=a-Math.floor(Math.log(i)*m)
}
else{
var m=(b-a)/Math.log(x),v=Math.floor(Math.log(i)*m+a)
}
return v
}
var c=[];
var labelCount = new Array();
var ts = new Object;
<b:loop values='data:labels' var='label'>
var theName = "<data:label.name/>";
ts[theName] = <data:label.count/>;
</b:loop>
for (t in ts){
if (!labelCount[ts[t]]){
labelCount[ts[t]] = new Array(ts[t])
}
}
var ta=cloudMin-1;
tz = labelCount.length - cloudMin;
lc2 = document.getElementById('labelCloud');
ul = document.createElement('ul');
ul.className = 'label-cloud';
for(var t in ts){
if(ts[t] < cloudMin){
continue;
}
for (var i=0;3 > i;i++) {
c[i]=s(minColor[i],maxColor[i],ts[t]-ta,tz)
}
var fs = s(minFontSize,maxFontSize,ts[t]-ta,tz);
li = document.createElement('li');
li.style.fontSize = fs+'px';
li.style.lineHeight = '1';
a = document.createElement('a');
a.title = ts[t]+' Posts in '+t;
a.style.color = 'rgb('+c[0]+','+c[1]+','+c[2]+')';
a.href = '/search/label/'+encodeURIComponent(t);
if (lcShowCount){
span = document.createElement('span');
span.innerHTML = '('+ts[t]+') ';
span.className = 'label-count';
a.appendChild(document.createTextNode(t));
li.appendChild(a);
li.appendChild(span);
}
else {
a.appendChild(document.createTextNode(t));
li.appendChild(a);
}
ul.appendChild(li);
abnk = document.createTextNode(' ');
ul.appendChild(abnk);
}
lc2.appendChild(ul);
</script>
<noscript>
<ul>
<b:loop values='data:labels' var='label'>
<li>
<b:if cond='data:blog.url == data:label.url'>
<data:label.name/>
<b:else/>
<a expr:href='data:label.url'><data:label.name/></a>
</b:if>
(<data:label.count/>)
</li>
</b:loop>
</ul>
</noscript>
<b:include name='quickedit'/>
</div>
</b:includable>
</b:widget>
It's done !
You can configurthe colors and font size to match your blog. At no. 3 step you added these variables
<script type='text/javascript'>
// Label Cloud User Variables
var cloudMin = 1;
var maxFontSize = 20;
var maxColor = [0,0,255];
var minFontSize = 10;
var minColor = [0,0,0];
var lcShowCount = false;
</script>
var cloudMin= 1;
This enable you to limit the no. of labels shown. If you keep this setting at 1 then it will show all the labels. If you enter in a higher number, then only labels that have at least that number of entries will appear in the cloud.
maxFontSize - sets the size of the label with the most amount entries.
maxColor - sets the color of that entry (in RGB format).
minFontSize - sets the size of the label with the least entries.
minColor - sets the color of that entry (in RGB format).
lcShowCount
If its false then label count is off and if it is true then label count is on.
