Can i align a text in a div with a geometric shape, like this
https://encrypted-tbn1.gstatic.com/images?q=tbn:ANd9GcQ5z8OYxnypDr09mmfFMunJj31x_XtfG3MFj0vlAa_ceoCnts0OfQ
without hiding some of text?
Update:
I need something like this, above is a circle, but also i need something like this for parallelogram:

Here's a js fiddle code

Found it some where.
Here's the script
var canvas = document.getElementById("canvas");
var ctx = canvas.getContext("2d");
var text = "'Twas the night before Christmas, when all through the house, Not a creature was stirring, not even a mouse. And so begins the story of the day of Christmas";
var font = "12pt verdana";
var textHeight = 15;
var lineHeight = textHeight + 5;
var lines = [];
var cx = 150;
var cy = 150;
var r = 100;
initLines();
wrapText();
ctx.beginPath();
ctx.arc(cx, cy, r, 0, Math.PI * 2, false);
ctx.closePath();
ctx.strokeStyle = "skyblue";
ctx.lineWidth = 2;
ctx.stroke();
// pre-calculate width of each horizontal chord of the circle
// This is the max width allowed for text
function initLines() {
for (var y = r * .90; y > -r; y -= lineHeight) {
var h = Math.abs(r - y);
if (y - lineHeight < 0) {
h += 20;
}
var length = 2 * Math.sqrt(h * (2 * r - h));
if (length && length > 10) {
lines.push({
y: y,
maxLength: length
});
}
}
}
// draw text on each line of the circle
function wrapText() {
var i = 0;
var words = text.split(" ");
while (i < lines.length && words.length > 0) {
line = lines[i++];
var lineData = calcAllowableWords(line.maxLength, words);
ctx.fillText(lineData.text, cx - lineData.width / 2, cy - line.y + textHeight);
words.splice(0, lineData.count);
};
}
// calculate how many words will fit on a line
function calcAllowableWords(maxWidth, words) {
var wordCount = 0;
var testLine = "";
var spacer = "";
var fittedWidth = 0;
var fittedText = "";
ctx.font = font;
for (var i = 0; i < words.length; i++) {
testLine += spacer + words[i];
spacer = " ";
var width = ctx.measureText(testLine).width;
if (width > maxWidth) {
return ({
count: i,
width: fittedWidth,
text: fittedText
});
}
fittedWidth = width;
fittedText = testLine;
}
}
yes this can be achieved through these links
link1 and link2.
and then set the div's by giving postioning :) cheers.
give border radius and get your shape. and use some margins to get it accurate. The link i have posted will help you.

Say I have a set of four or more points that are on the perimeter of a rectangle, and that the rectangle is rotated by some unknown amount. I know that at least one point is on each side of the rectangle. One arbitrary side point is designated (0, 0), and the other points are the distance from this starting point. How can I get the non-rotated corner points of this rectangle?
assuming you're not trying to find a unique solution:
rotate your points around 0,0 until the top-most, bottom-most,
left-most, and right-most points are all different points
draw horizontal lines through the top-most and bottom-most, and vertical lines through the left-most and right-most
you're done

I am trying to add random segments along the path of a rectangle. Here is my jsfiddle http://jsfiddle.net/hhND7/1/
<canvas id='canvas' resize style='' style='padding:0; margin:0;'></canvas>
<script type="text/paperscript" canvas="canvas" >
var rect = new Path.Rectangle({x:200, y:100}, new Size(80, 100))
rect.strokeColor = 'gray'
rect.selected = true;
var pathCuts = rands(20, 0, 360).sort(function(a,b){return a - b});
var tArr = [];
for ( var i=0; i<pathCuts.length; i++){
var loc = rect.getLocationAt(pathCuts[i]);
tArr.push(loc.point);
var sE = new Path.Circle(loc.point, 2);
sE.strokeColor = 'red';
}
rect.insertSegments(1, tArr);
function rands(n, min, max) {
var range = max - min;
if (range < n)
throw new RangeError("Specified number range smaller than count requested");
function shuffle() {
var deck = [], p, t;
for (var i = 0; i < range; ++i)
deck[i] = i + min;
for (i = range - 1; i > 0; --i) {
p = Math.floor(Math.random() * i);
t = deck[i];
deck[i] = deck[p];
deck[p] = t;
}
return deck.slice(0, n);
}
function find() {
var used = {}, rv = [], r;
while (rv.length < n) {
r = Math.floor(Math.random() * range + min);
if (!used[r]) {
used[r] = true;
rv.push(r);
}
}
return rv;
}
return range < 3 * n ? shuffle() : find();
}
</script>
I think the problem is with the insertSegments function. But i can not find a solution.
If you want it to still look like the original polygon, you need to sort in the positions of the original segments. Since you can replace a path's segments with an array of curveLocation , you can just add the locations of these points to tArr, then sort by each element by it's offset:
var pathCuts = rands(20, 0, rect.length);
var tArr = [];
for ( var i=0; i<pathCuts.length; i++){
var loc = rect.getLocationAt(pathCuts[i]);
tArr.push(loc);
var sE = new Path.Circle(loc.point, 2);
sE.strokeColor = 'red';
}
for ( var i = 0, l = rect.segments.length; i < l; i++){
tArr.push(rect.segments[i].location);
}
tArr.sort(function(a,b){return a.offset - b.offset})
rect.segments = tArr;
I have 4 tables that need to scroll, they are set up as follows:
Table1(static)
Table2(Horizontal Scrolling)
Table3(Vertical Scrolling)
Table4(Horizontal and Vertical Scrolling)
Table1 Table2
Table3 Table4
The tricky part of this is that Table 3 and 4 need to keep in sync as this is a listing of data broken out into two tables. Table 2 and 4 are in the same situation.
Any ideas?
No Javascript please as we have a script that works, but it is far too slow to work.
Thanks.

We got the code from this link.
I hope this helps.
As it stands, the code is far too bulky to process the amount of data we need to. We have approximately 5000 rows of data per month that needs to be displayed on the page.
If by "need to keep in sync" you mean that when you scroll one of them, the other scrolls too, you can't do this with CSS, because you can't manipulate scroll position using CSS.
And one more thing, have in mind that scrollbar in IE goes inside the element and overlaps 20px of this element (there is a workaround for this), and in all other browsers scrollbar goes outside the element.
You can use CSS to set the height of an element and then set overflow:auto (this will give you scroll bars when needed).
Its very hard to get rows of a table to scroll properly. I've been trying with things such as wrapping a table row in a div (or vice versa) and setting a max-height and overflow of that div.
That's the best I can do with out seeing what you are trying to do.

I appoligize, this part will not format no matter what I do, sorry about the poor formatting.
In ZedGraph, how do I show text labels for each point and in the XAxis all together?
If I do
myPane.XAxis.Type = AxisType.Text;
myPane.XAxis.Scale.TextLabels = array_of_string;
I get labels on the XAxis like this
And if I do
for (int i = 0; i < myCurve.Points.Count; i++)
{
PointPair pt = myCurve.Points[i];
// Create a text label from the Y data value
TextObj text = new TextObj(
pt.Y.ToString("f0"), pt.X, pt.Y + 0.1,
CoordType.AxisXYScale, AlignH.Left, AlignV.Center);
text.ZOrder = ZOrder.A_InFront;
text.FontSpec.Angle = 0;
myPane.GraphObjList.Add(text);
}
I get labels on the curve, like this
But if I do both at the same time, labels on the curve disappear.
Is there a way to combine both kind of labels?
I've changed my answer after you clarified the question.
You just have to remember to position the labels correctly:
<%
System.Collections.Generic.List<ZedGraphWebPointPair> points = new System.Collections.Generic.List<ZedGraphWebPointPair>();
for (int i = 0; i < 15; i++)
{
// Let's have some fun with maths
points.Add(new ZedGraphWebPointPair
{
X = i,
Y = Math.Pow(i - 10, 2) * -1 + 120
});
}
System.Collections.Generic.List<string> XAxisLabels = new System.Collections.Generic.List<string>();
TestGraph.CurveList.Add(new ZedGraphWebLineItem { Color = System.Drawing.Color.Red });
TestGraph.XAxis.Scale.FontSpec.Size = 9;
int j = 1;
foreach (ZedGraphWebPointPair point in points)
{
// Add the points we calculated
TestGraph.CurveList[0].Points.Add(point);
// Add the labels for the points
TestGraph.GraphObjList.Add(new ZedGraphWebTextObj
{
Location =
{
CoordinateFrame = ZedGraph.CoordType.XChartFractionYScale,
// Make sure we position them according to the CoordinateFrame
X = Convert.ToSingle(j) / points.Count - 0.05f,
Y = Convert.ToSingle(point.Y) + 3f,
AlignV = ZedGraph.AlignV.Top
},
Text = point.Y.ToString(),
FontSpec = { Angle = 90, Size = 9, Border = { IsVisible = false } }
});
// Add the labels for the XAxis
XAxisLabels.Add(String.Format("P{0}", j));
j++;
}
TestGraph.RenderGraph += delegate(ZedGraphWeb zgw, System.Drawing.Graphics g, ZedGraph.MasterPane mp)
{
ZedGraph.GraphPane gp = mp[0];
gp.XAxis.Type = ZedGraph.AxisType.Text;
gp.XAxis.Scale.TextLabels = XAxisLabels.ToArray();
};
%>
That code will produce this graph:
If the axis type is text, the code below is easier to get x-coordinates of the points ;)
for (int tPoint = 0; tPoint < curve.Points.Count; tPoint++)
{
TextObj text = new TextObj(curve.Points[tPoint].Y.ToString(), curve.Points[tPoint].X, curve.Points[tPoint].Y + 10);
}
