/* Flot plugin for rendering pie charts.
Copyright (c) 2007-2013 IOLA and Ole Laursen.
Licensed under the MIT license.
The plugin assumes that each series has a single data value, and that each
value is a positive integer or zero. Negative numbers don't make sense for a
pie chart, and have unpredictable results. The values do NOT need to be
passed in as percentages; the plugin will calculate the total and per-slice
percentages internally.
* Created by Brian Medendorp
* Updated with contributions from btburnett3, Anthony Aragues and Xavi Ivars
The plugin supports these options:
series: {
pie: {
show: true/false
radius: 0-1 for percentage of fullsize, or a specified pixel length, or 'auto'
innerRadius: 0-1 for percentage of fullsize or a specified pixel length, for creating a donut effect
startAngle: 0-2 factor of PI used for starting angle (in radians) i.e 3/2 starts at the top, 0 and 2 have the same result
tilt: 0-1 for percentage to tilt the pie, where 1 is no tilt, and 0 is completely flat (nothing will show)
offset: {
top: integer value to move the pie up or down
left: integer value to move the pie left or right, or 'auto'
},
stroke: {
color: any hexidecimal color value (other formats may or may not work, so best to stick with something like '#FFF')
width: integer pixel width of the stroke
},
label: {
show: true/false, or 'auto'
formatter: a user-defined function that modifies the text/style of the label text
radius: 0-1 for percentage of fullsize, or a specified pixel length
background: {
color: any hexidecimal color value (other formats may or may not work, so best to stick with something like '#000')
opacity: 0-1
},
threshold: 0-1 for the percentage value at which to hide labels (if they're too small)
},
combine: {
threshold: 0-1 for the percentage value at which to combine slices (if they're too small)
color: any hexidecimal color value (other formats may or may not work, so best to stick with something like '#CCC'), if null, the plugin will automatically use the color of the first slice to be combined
label: any text value of what the combined slice should be labeled
}
highlight: {
opacity: 0-1
}

// When combining smaller slices into an 'other' slice, we need to
// add a new series. Since Flot gives plugins no way to modify the
// list of series, the pie plugin uses a hack where the first call
// to processDatapoints results in a call to setData with the new
// list of series, then subsequent processDatapoints do nothing.
// The plugin-global 'processed' flag is used to control this hack;
// it starts out false, and is set to true after the first call to
// processDatapoints.
// Unfortunately this turns future setData calls into no-ops; they
// call processDatapoints, the flag is true, and nothing happens.
// To fix this we'll set the flag back to false here in draw, when
// all series have been processed, so the next sequence of calls to
// processDatapoints once again starts out with a slice-combine.
// This is really a hack; in 0.9 we need to give plugins a proper

This plugin will draw labels next to the plotted points on your graph. Tested on
a scatter graph, may or may not work with other graph types. Best suited to
situations involving a smaller number of points.
usage -
<style type="text/css">
.myCSSClass
{
font-size: 9px;
color: #AD8200;
padding: 2px;
opacity: 0.80;
}
</style>
<script type="text/javascript">
var names = [
"foo",
"bar"
];
var data = { data: [[1,1],[2,2]], showLabels: true, labels: names, labelPlacement: "left", labelClass: "myCSSClass" };
$.plot($("#placeholder), [data], options);
</script>
For each series that you want labeled you need to set showLabels to true, set labels to an array of label names (strings),
set the labelClass to a css class you have defined for your labels and optionally set labelPlacement to one of "left", "right",
"above" or "below" (below by default if not specified). Placement can be fine tuned by setting the margins in your label class.
Note: if the labelClass is not explicitly supplied in the development version of flot (> v0.7), the plugin will auto generate
a label class as "seriesLabelx" where x is the 1-based index of the data series. I.e. the first dataseries will be seriesLabel1,
the second seriesLabel2, etc.
For the names, the array should be the same length as the data. If any are missing (null) then the label for that point will
be skipped. For example, to label only the 1st and 3rd points:
var names = ["foo", null, "bar"];
Update: Version 0.2
Added support for drawing labels using canvas.fillText. The advantages are that, in theory, drawing to the canvas should be
faster, but the primary reason is that in some browsers, the labels added as absolutely positioned div elements won't show up
if you print the page. So if you want to print your graphs, you should probably use canvasRender.
The disadvantage is that you lose the flexibility of defining the label with a CSS class.
Options added to series (with defaults):
canvasRender: false, // false will add divs to the DOM rather than use canvas.fillText
cColor: "#000", // color for the text if using canvasRender
cFont: "9px, san-serif", // font for the text if using canvasRender
cPadding: 4 // Padding to add when using canvasRender (where padding is added depends on
// labelPlacement)
Also, version 0.2 takes into account the radius of the data points when placing the labels.

*
* Version 1.1.
*
* Inspiration from jQuery color animation plugin by John Resig.
*
* Released under the MIT license by Ole Laursen, October 2009.
*
* Examples:
*
* $.color.parse("#fff").scale('rgb', 0.25).add('a', -0.5).toString()
* var c = $.color.extract($("#mydiv"), 'background-color');
* console.log(c.r, c.g, c.b, c.a);
* $.color.make(100, 50, 25, 0.4).toString() // returns "rgba(100,50,25,0.4)"
*
* Note that .scale() and .add() return the same modified object

*
* V. 1.1: Fix error handling so e.g. parsing an empty string does

/* Flot plugin for rendering pie charts.
Copyright (c) 2007-2013 IOLA and Ole Laursen.
Licensed under the MIT license.
The plugin assumes that each series has a single data value, and that each
value is a positive integer or zero. Negative numbers don't make sense for a
pie chart, and have unpredictable results. The values do NOT need to be
passed in as percentages; the plugin will calculate the total and per-slice
percentages internally.
* Created by Brian Medendorp
* Updated with contributions from btburnett3, Anthony Aragues and Xavi Ivars
The plugin supports these options:
series: {
pie: {
show: true/false
radius: 0-1 for percentage of fullsize, or a specified pixel length, or 'auto'
innerRadius: 0-1 for percentage of fullsize or a specified pixel length, for creating a donut effect
startAngle: 0-2 factor of PI used for starting angle (in radians) i.e 3/2 starts at the top, 0 and 2 have the same result
tilt: 0-1 for percentage to tilt the pie, where 1 is no tilt, and 0 is completely flat (nothing will show)
offset: {
top: integer value to move the pie up or down
left: integer value to move the pie left or right, or 'auto'
},
stroke: {
color: any hexidecimal color value (other formats may or may not work, so best to stick with something like '#FFF')
width: integer pixel width of the stroke
},
label: {
show: true/false, or 'auto'
formatter: a user-defined function that modifies the text/style of the label text
radius: 0-1 for percentage of fullsize, or a specified pixel length
background: {
color: any hexidecimal color value (other formats may or may not work, so best to stick with something like '#000')
opacity: 0-1
},
threshold: 0-1 for the percentage value at which to hide labels (if they're too small)
},
combine: {
threshold: 0-1 for the percentage value at which to combine slices (if they're too small)
color: any hexidecimal color value (other formats may or may not work, so best to stick with something like '#CCC'), if null, the plugin will automatically use the color of the first slice to be combined
label: any text value of what the combined slice should be labeled
}
highlight: {
opacity: 0-1
}
}
}
More detail and specific examples can be found in the included HTML file.

// WARNING: HACK! REWRITE THIS CODE AS SOON AS POSSIBLE!
// When combining smaller slices into an 'other' slice, we need to
// add a new series. Since Flot gives plugins no way to modify the
// list of series, the pie plugin uses a hack where the first call
// to processDatapoints results in a call to setData with the new
// list of series, then subsequent processDatapoints do nothing.
// The plugin-global 'processed' flag is used to control this hack;
// it starts out false, and is set to true after the first call to
// processDatapoints.
// Unfortunately this turns future setData calls into no-ops; they
// call processDatapoints, the flag is true, and nothing happens.
// To fix this we'll set the flag back to false here in draw, when
// all series have been processed, so the next sequence of calls to
// processDatapoints once again starts out with a slice-combine.
// This is really a hack; in 0.9 we need to give plugins a proper

This plugin will draw labels next to the plotted points on your graph. Tested on
a scatter graph, may or may not work with other graph types. Best suited to
situations involving a smaller number of points.
usage -
<style type="text/css">
.myCSSClass
{
font-size: 9px;
color: #AD8200;
padding: 2px;
opacity: 0.80;
}
</style>
<script type="text/javascript">
var names = [
"foo",
"bar"
];
var data = { data: [[1,1],[2,2]], showLabels: true, labels: names, labelPlacement: "left", labelClass: "myCSSClass" };
$.plot($("#placeholder), [data], options);
</script>
For each series that you want labeled you need to set showLabels to true, set labels to an array of label names (strings),
set the labelClass to a css class you have defined for your labels and optionally set labelPlacement to one of "left", "right",
"above" or "below" (below by default if not specified). Placement can be fine tuned by setting the margins in your label class.
Note: if the labelClass is not explicitly supplied in the development version of flot (> v0.7), the plugin will auto generate
a label class as "seriesLabelx" where x is the 1-based index of the data series. I.e. the first dataseries will be seriesLabel1,
the second seriesLabel2, etc.
For the names, the array should be the same length as the data. If any are missing (null) then the label for that point will
be skipped. For example, to label only the 1st and 3rd points:
var names = ["foo", null, "bar"];
Update: Version 0.2
Added support for drawing labels using canvas.fillText. The advantages are that, in theory, drawing to the canvas should be
faster, but the primary reason is that in some browsers, the labels added as absolutely positioned div elements won't show up
if you print the page. So if you want to print your graphs, you should probably use canvasRender.
The disadvantage is that you lose the flexibility of defining the label with a CSS class.
Options added to series (with defaults):
canvasRender: false, // false will add divs to the DOM rather than use canvas.fillText
cColor: "#000", // color for the text if using canvasRender
cFont: "9px, san-serif", // font for the text if using canvasRender
cPadding: 4 // Padding to add when using canvasRender (where padding is added depends on
// labelPlacement)
Also, version 0.2 takes into account the radius of the data points when placing the labels.

/* Plugin for jQuery for working with colors.
*
* Version 1.1.
*
* Inspiration from jQuery color animation plugin by John Resig.
*
* Released under the MIT license by Ole Laursen, October 2009.
*
* Examples:
*
* $.color.parse("#fff").scale('rgb', 0.25).add('a', -0.5).toString()
* var c = $.color.extract($("#mydiv"), 'background-color');
* console.log(c.r, c.g, c.b, c.a);
* $.color.make(100, 50, 25, 0.4).toString() // returns "rgba(100,50,25,0.4)"
*
* Note that .scale() and .add() return the same modified object
* instead of making a new one.
*
* V. 1.1: Fix error handling so e.g. parsing an empty string does
* produce a color rather than just crashing.

* Note that we must ALWAYS check specially whether those values are MIN_VALUE

*
* When there is a mapping, there are two possible styles in which
* these mappings are used. In the BY_PART style, each part (i.e. in
* between hyphens) of the passed in css name is rewritten according
* to the map. In the BY_WHOLE style, the full css name is looked up in
* the map directly. If a rewrite is not specified by the map, the
* compiler will output a warning.
*
* When the mapping is passed to the compiler, it will replace calls
* to goog.getCssName with the strings from the mapping, e.g.
* var x = goog.getCssName('foo');
* var y = goog.getCssName(this.baseClass, 'active');
* becomes:
* var x= 'foo';
* var y = this.baseClass + '-active';

* only the modifier will be processed, as it is assumed the first
* argument was generated as a result of calling goog.getCssName.

Usage Note:
-----------
Do not use both ajaxSubmit and ajaxForm on the same form. These
functions are mutually exclusive. Use ajaxSubmit if you want
to bind your own submit handler to the form. For example,
$(document).ready(function() {
$('#myForm').on('submit', function(e) {
e.preventDefault(); // <-- important
$(this).ajaxSubmit({
target: '#output'
});
});
});
Use ajaxForm when you want the plugin to manage all the event binding
for you. For example,
$(document).ready(function() {
$('#myForm').ajaxForm({
target: '#output'
});
});
You can also use ajaxForm with delegation (requires jQuery v1.7+), so the
form does not have to exist when you invoke ajaxForm:
$('#myForm').ajaxForm({
delegation: true,
target: '#output'
});
When using ajaxForm, the ajaxSubmit function will be invoked for you
at the appropriate time.

Usage Note:
-----------
Do not use both ajaxSubmit and ajaxForm on the same form. These
functions are mutually exclusive. Use ajaxSubmit if you want
to bind your own submit handler to the form. For example,
$(document).ready(function() {
$('#myForm').bind('submit', function(e) {
e.preventDefault(); // <-- important
$(this).ajaxSubmit({
target: '#output'
});
});
});
Use ajaxForm when you want the plugin to manage all the event binding
for you. For example,
$(document).ready(function() {
$('#myForm').ajaxForm({
target: '#output'
});
});
You can also use ajaxForm with delegation (requires jQuery v1.7+), so the
form does not have to exist when you invoke ajaxForm:
$('#myForm').ajaxForm({
delegation: true,
target: '#output'
});
When using ajaxForm, the ajaxSubmit function will be invoked for you
at the appropriate time.
