In the position property, there are two options : "my" and "at".
I don't understand how to configure the position of the popup bubble through these options.
What do they mean?
In order to figure out these options clearly, I found an example on-line, but still cannot figure out.
For example, when the bubble is shown on the left of the input area, but the value of "my" is 'right center', why is that?
Why call tooltip() twice? One tooltip with arguements is called within on(), and another one without arguements is on outside the on() trigger?
Why is that?
Here is the example: http://jsfiddle.net/tj_vantoll/kyBwU/
$('input[type="radio"]').on('change', function() {
var className = $(this).val();
var position;
switch (className) {
case 'top':
position = { my: 'center bottom', at: 'center top-10' };
break;
case 'bottom':
position = { my: 'center top', at: 'center bottom+10' };
break;
case 'left':
position = { my: 'right center', at: 'left-10 center' };
break;
case 'right':
position = { my: 'left center', at: 'right+10 center' };
break;
}
position.collision = 'none';
$('input[type="text"]').tooltip('option', 'position', position);
$('input[type="text"]').tooltip('option', 'tooltipClass', className);
});
$('#options').buttonset();
$('input[type="text"]').tooltip();
$('input[value="right"]').trigger('change');
And I tried to create my own, somehow, the last input text field is always preselected.
It is my code: http://jsfiddle.net/matildayipan/sks358zo/18/
That's what we have documentation for.
The jQuery UI .position() method allows you to position an element relative to the window, document, another element, or the cursor/mouse, without worrying about offset parents.
my (default: "center") Type: String
Defines which position on the
element being positioned to align with the target element: "horizontal
vertical" alignment. A single value such as "right" will be normalized
to "right center", "top" will be normalized to "center top" (following
CSS convention). Acceptable horizontal values: "left", "center",
"right". Acceptable vertical values: "top", "center", "bottom".
Example: "left top" or "center center". Each dimension can also
contain offsets, in pixels or percent, e.g., "right+10 top-25%".
Percentage offsets are relative to the element being positioned.
at (default: "center") Type: String
Defines which position on the target
element to align the positioned element against: "horizontal vertical"
alignment. See the my option for full details on possible values.
Percentage offsets are relative to the target element.

I have a system with lots of highcharts which can be positioned basically anywhere on the page.
Some are very small (e.g. 50px x 50px).
I see we can set tooltip.outside : true
tooltip: {
outside: true
}
This stops the tooltip taking over the whole chart container by breaking it out of the chart and into the window.
However this can cause overflow issues with the window when you're near the edge of the page and I personally prefer a static tooltip.
I'd like to always fix the tooltip to float above the chart, top left with a bit of padding, which for my application will almost always be visible and will avoid overflow issues, e.g.;
I've looked into setting a custom positioner, however, as the "outside" tooltip is now part of the window and not relative to the chart, the positioner sets a fixed position, which isn't suitable for my application.
I'd like the tooltip to always be above the chart regardless of mouse or scroll positions.
Of course I could add a custom element and position it above the chart myself, then applying the tooltip to that, but we have a lot of charts and this seems cumbersome.
Tooltip outside Fiddle
Suggestions?
Thanks
After a bit of poking around in the highstock Tooltip.prototype.getPosition code, it turns out what I needed was this.point.chart.pointer.getChartPosition();
tooltip: {
distance: 40,
outside: true,
positioner: function () {
var point = this;
var chart = point.chart;
var chartPosition = chart.pointer.getChartPosition();
var distance = point.distance;
//Position relative to renderTo container
return {
x: chartPosition.left - distance,
y: chartPosition.top - distance - (point.options.useHTML == true ? point.label.div.offsetHeight : point.label.height)
}
//Alternatively - Position relative to chart plot (ignoring legend)
var containerScaling = chart.containerScaling;
var scaleX = function (val) {
return (containerScaling ? val * containerScaling.scaleX : val);
};
var scaleY = function (val) {
return (containerScaling ? val * containerScaling.scaleY : val);
};
return {
x: chartPosition.left - distance + scaleX(chart.plotLeft),
y: chartPosition.top - distance + scaleY(chart.plotTop) - point.label.height
}
},
},
See working fiddle.
I find it odd that this method is attached to pointer, but it's what I was after.
One thing to note, in the fiddle I use point.label.height, if useHTML:true; use point.label.div.height.
What about using the positioner callback without setting the 'outside' option? It will set the wanted position inside the chart area.

The space for xAxis generally is rendered dynamically by the Highcharts library and add the ellipsis in the correct place, making it display from the start and cutting it when it stop displaying it on the graph with some ellipsis.
When I try to change that space to not render dynamically, the property marginBottom does it,but it stops picking up when the text should start displaying and the start of the text is cutted from the down of the graph. Is there a way to render correctly the text at the bottom from the highcharts? I Do need it to be rotate 270 degrees, and not let the auto rotate work, and don't want to collapse more part of the graph just for displaying the text.
Here is a sample when that happes:
Highcharts.chart('container', {
chart: {
height: 350,
spacingBottom: 0,
marginBottom: 50,
type: "column"
},
series: [{
name: 'Total',
data: [1,2,3,4,5]
}],
xAxis: {
categories: ["very long name to test if the characters are rigth and cropped",
"Not so long but long enough", "I still am long and out of the screen",
"lets see how is cropped", "cropped", "crop"],
labels: {
rotation: 270
}
}
});
Sample fiddle with marginBottom : https://jsfiddle.net/ragmar/6ru4hze3/
If you remove the marginBottom, even the legend move down a bit.
It is possible to do this behavior? even including some css?
Thanks in advance
To make it work the way you want, you have to make some modifications in Highcharts core. For example you can do not use marginBottom option, but set fixed value as a commonWidth variable in renderUnsquish method:
if (attr.rotation) {
commonWidth = (
maxLabelLength > chart.chartHeight * 0.5 ?
40 : // changed from 'chart.chartHeight * 0.33'
maxLabelLength
);
if (!textOverflowOption) {
commonTextOverflow = 'ellipsis';
}
}

I want to implement a feature somewhat like (but not exactly like) the hint mode of the Mahjong Titans game in Windows. In that game, you can ask the game to show you a tile that matches the tile you're on.
In my app, when the user hovers the pointer over a cell of my table, I want to display a tooltip but also add a class to the underlying cell, as well as to some other related cells, in order to highlight these cells for the duration of the tooltip display; the highlight would disappear when the tooltip closes.
The cell click event is already dedicated to some other behavior. This related-cells-highlighting behavior must be an ancillary behavior of the tooltip.
I am creating the tooltip like this now:
$("#my-table tbody td.foo").tooltip({
content: function () {
// figure out the custom message to be displayed
}
},
items: "td.foo",
position: { my: "left+15 center", at: "left top" },
show: {
delay: 666
}
})
Can this instantiation approach be extended with functions that are invoked when the tooltip is displayed and when the tooltip is taken down?
In the function tied to the tooltip's opening, I would figure out which cells are involved and add the correct class to them; in the function related to the tooltip's closing, I would remove that class from those cells.
I think you're looking for the open and close events.
$("#my-table tbody td.foo").tooltip({
content: function () {
// figure out the custom message to be displayed
},
items: "td.foo",
position: {
my: "left+15 center",
at: "left top"
},
show: {
delay: 666
},
open: function (event, ui) {// do stuff when tooltip opens...
},
close: function (event, ui) {// do other stuff when tooltip closes...
}
});
I am building a pie chart where the labels for the data points can very greatly in length, the legend is configured to be vertical and positioned on the left side.
I have added a label element to the bottom of the chart that shows the total of all data points.
The problem I am facing is that the positioning of this label (via the style element) is based on how wide the legend is, which occasionally if the legend is wide enough will be pushed off the right side of the chart.
Does anyone know of a way that I can style this label so that is positioned based solely on the width of the entire chart.
Here is the styling applied to the label (I tried adding the position value but this didn't appear to do anything):
style: {
top: '325px',
position: 'absolute',
left: '-160px',
'font-size': '175%'
}
Here is an example of the chart that I'm working with, you can see that the value for the total has bee cut off.
EDIT:
As per Sebastian's comment I was able to effectively solve the issue by using the legend label formatter to limit the length of the series names. Here is the code:
labelFormatter: function () {
var formattedName = this.name;
if (formattedName.length > 17) {
formattedName = formattedName.substr(0, 14) + '...';
}
return formattedName;
}
Have you tried to use labelFormatter http://api.highcharts.com/highcharts#legend.labelFormatter ?
I'm using jQuery UI Select Menu and occasionally have some issues.
This is located at the top left of my users' pages. Using the "dropdown/address" type, sometimes (seemingly random), the dropdown opens UP instead of DOWN, and you can't select any options in it except the first one because it's all "above" the screen.
Anyone know of a setting/option in there to force it to open down? Thanks!
update.... 11/23/11 1:11pm est
Here is some code of the call:
$(function(){
$('select#selectionA').selectmenu({
style:'dropdown',
menuWidth: 220,
positionOptions: {
collision: 'none'
},
format: addressFormatting
});
});
The plugin uses the Position utility of the jQuery UI library. If you look at the default options in the source of the plugin, there is a positionOptions property that is used in the function _refreshPosition():
options: {
transferClasses: true,
typeAhead: 1000,
style: 'dropdown',
positionOptions: {
my: "left top",
at: "left bottom",
offset: null
},
width: null,
menuWidth: null,
handleWidth: 26,
maxHeight: null,
icons: null,
format: null,
bgImage: function() {},
wrapperElement: "<div />"
}
_refreshPosition: function() {
var o = this.options;
// if its a pop-up we need to calculate the position of the selected li
if ( o.style == "popup" && !o.positionOptions.offset ) {
var selected = this._selectedOptionLi();
var _offset = "0 " + ( this.list.offset().top - selected.offset().top - ( this.newelement.outerHeight() + selected.outerHeight() ) / 2);
}
// update zIndex if jQuery UI is able to process
this.listWrap
.zIndex( this.element.zIndex() + 1 )
.position({
// set options for position plugin
of: o.positionOptions.of || this.newelement,
my: o.positionOptions.my,
at: o.positionOptions.at,
offset: o.positionOptions.offset || _offset,
collision: o.positionOptions.collision || 'flip'
});
}
You can see it uses a default value 'flip' if none is provided for the collision option of the position utility which is. According to jQuery UI documentation:
flip: to the opposite side and the collision detection is run again to see if it will fit. If it won't fit in either position, the center option should be used as a fall back.
fit: so the element keeps in the desired direction, but is re-positioned so it fits.
none: not do collision detection.
So i guess you could pass an option when initializing the plugin to define none for the collision option:
$('select').selectmenu({
positionOptions: {
collision: 'none'
}
});
Have not tested yet, this is just by looking at the code.
Edit following comment
I've noticed that the version of the javascript available on github and the one used on the plugin website are not the same. I don't know which one you are using but the one used on the website does not have a positionOptions option actually, so it has no effect to specify it when calling selectmenu().
It seems it's not possible to link directly to the javascript on the site so here's some code to illustrate:
defaults: {
transferClasses: true,
style: 'popup',
width: null,
menuWidth: null,
handleWidth: 26,
maxHeight: null,
icons: null,
format: null
}
_refreshPosition: function(){
//set left value
this.list.css('left', this.newelement.offset().left);
//set top value
var menuTop = this.newelement.offset().top;
var scrolledAmt = this.list[0].scrollTop;
this.list.find('li:lt('+this._selectedIndex()+')').each(function(){
scrolledAmt -= $(this).outerHeight();
});
if(this.newelement.is('.'+this.widgetBaseClass+'-popup')){
menuTop+=scrolledAmt;
this.list.css('top', menuTop);
}
else {
menuTop += this.newelement.height();
this.list.css('top', menuTop);
}
}
I was able to make it work as I first described with the version from github. In my opinion it is a more recent/complete version. Besides it was updated a few days ago.
I have created a small test page with two selects. I've changed for both the position for the dropdown to show above.
The first one does not specify the collision option, thus 'flip' is used and the dropdown displays below because there is not enough space above.
The second has 'none' specified and the dropdown shows above even if there is not enough space.
I've put the small test project on my dropbox.
I'm the maintainer of the Selectmenu plugin. There are currently three versions, please see the wiki for more information: https://github.com/fnagel/jquery-ui/wiki/Selectmenu
I assume you're using my fork. The collision problem could be related to this fix https://github.com/fnagel/jquery-ui/pull/255, please try the latest version.
To force a scrollbar use option maxHeight.
