/* Flot plugin for showing crosshairs when the mouse hovers over the plot.
Copyright (c) 2007-2014 IOLA and Ole Laursen.
Licensed under the MIT license.
The plugin supports these options:
crosshair: {
mode: null or "x" or "y" or "xy"
color: color
lineWidth: number
}
Set the mode to one of "x", "y" or "xy". The "x" mode enables a vertical
crosshair that lets you trace the values on the x axis, "y" enables a
horizontal crosshair and "xy" enables them both. "color" is the color of the
crosshair (default is "rgba(170, 0, 0, 0.80)"), "lineWidth" is the width of
the drawn lines (default is 1).
The plugin also adds four public methods:
- setCrosshair( pos )
Set the position of the crosshair. Note that this is cleared if the user
moves the mouse. "pos" is in coordinates of the plot and should be on the
form { x: xpos, y: ypos } (you can use x2/x3/... if you're using multiple
axes), which is coincidentally the same format as what you get from a
"plothover" event. If "pos" is null, the crosshair is cleared.
- clearCrosshair()
Clear the crosshair.
- lockCrosshair(pos)
Cause the crosshair to lock to the current location, no longer updating if
the user moves the mouse. Optionally supply a position (passed on to
setCrosshair()) to move it to.
Example usage:
var myFlot = $.plot( $("#graph"), ..., { crosshair: { mode: "x" } } };
$("#graph").bind( "plothover", function ( evt, position, item ) {
if ( item ) {
// Lock the crosshair to the data point being hovered
myFlot.lockCrosshair({
x: item.datapoint[ 0 ],
y: item.datapoint[ 1 ]
});
} else {
// Return normal crosshair operation
myFlot.unlockCrosshair();
}
});
- unlockCrosshair()
Free the crosshair to move again after locking it.

/* Flot plugin for computing bottoms for filled line and bar charts.
Copyright (c) 2007-2013 IOLA and Ole Laursen.
Licensed under the MIT license.
The case: you've got two series that you want to fill the area between. In Flot
terms, you need to use one as the fill bottom of the other. You can specify the
bottom of each data point as the third coordinate manually, or you can use this
plugin to compute it for you.
In order to name the other series, you need to give it an id, like this:
var dataset = [
{ data: [ ... ], id: "foo" } , // use default bottom
{ data: [ ... ], fillBetween: "foo" }, // use first dataset as bottom
];
$.plot($("#placeholder"), dataset, { lines: { show: true, fill: true }});
As a convenience, if the id given is a number that doesn't appear as an id in
the series, it is interpreted as the index in the array instead (so fillBetween:
0 can also mean the first series).
Internally, the plugin modifies the datapoints in each series. For line series,
extra data points might be inserted through interpolation. Note that at points
where the bottom line is not defined (due to a null point or start/end of line),
the current line will show a gap too. The algorithm comes from the
jquery.flot.stack.js plugin, possibly some code could be shared.

/* 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.

// 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
// way to modify series before any processing begins.

/* Flot plugin for selecting regions of a plot.
Copyright (c) 2007-2013 IOLA and Ole Laursen.
Licensed under the MIT license.
The plugin supports these options:
selection: {
mode: null or "x" or "y" or "xy",
color: color,
shape: "round" or "miter" or "bevel",
minSize: number of pixels
}
Selection support is enabled by setting the mode to one of "x", "y" or "xy".
In "x" mode, the user will only be able to specify the x range, similarly for
"y" mode. For "xy", the selection becomes a rectangle where both ranges can be
specified. "color" is color of the selection (if you need to change the color
later on, you can get to it with plot.getOptions().selection.color). "shape"
is the shape of the corners of the selection.
"minSize" is the minimum size a selection can be in pixels. This value can
be customized to determine the smallest size a selection can be and still
have the selection rectangle be displayed. When customizing this value, the
fact that it refers to pixels, not axis units must be taken into account.
Thus, for example, if there is a bar graph in time mode with BarWidth set to 1
minute, setting "minSize" to 1 will not make the minimum selection size 1
minute, but rather 1 pixel. Note also that setting "minSize" to 0 will prevent
"plotunselected" events from being fired when the user clicks the mouse without
dragging.
When selection support is enabled, a "plotselected" event will be emitted on
the DOM element you passed into the plot function. The event handler gets a
parameter with the ranges selected on the axes, like this:
placeholder.bind( "plotselected", function( event, ranges ) {
alert("You selected " + ranges.xaxis.from + " to " + ranges.xaxis.to)
// similar for yaxis - with multiple axes, the extra ones are in
// x2axis, x3axis, ...
});
The "plotselected" event is only fired when the user has finished making the
selection. A "plotselecting" event is fired during the process with the same
parameters as the "plotselected" event, in case you want to know what's
happening while it's happening,
A "plotunselected" event with no arguments is emitted when the user clicks the
mouse to remove the selection. As stated above, setting "minSize" to 0 will
destroy this behavior.
The plugin allso adds the following methods to the plot object:
- setSelection( ranges, preventEvent )
Set the selection rectangle. The passed in ranges is on the same form as
returned in the "plotselected" event. If the selection mode is "x", you
should put in either an xaxis range, if the mode is "y" you need to put in
an yaxis range and both xaxis and yaxis if the selection mode is "xy", like
this:
setSelection({ xaxis: { from: 0, to: 10 }, yaxis: { from: 40, to: 60 } });
setSelection will trigger the "plotselected" event when called. If you don't
want that to happen, e.g. if you're inside a "plotselected" handler, pass
true as the second parameter. If you are using multiple axes, you can
specify the ranges on any of those, e.g. as x2axis/x3axis/... instead of
xaxis, the plugin picks the first one it sees.
- clearSelection( preventEvent )
Clear the selection rectangle. Pass in true to avoid getting a
"plotunselected" event.
- getSelection()
Returns the current selection in the same format as the "plotselected"
event. If there's currently no selection, the function returns null.

/* Flot plugin for stacking data sets rather than overlyaing them.
Copyright (c) 2007-2014 IOLA and Ole Laursen.
Licensed under the MIT license.
The plugin assumes the data is sorted on x (or y if stacking horizontally).
For line charts, it is assumed that if a line has an undefined gap (from a
null point), then the line above it should have the same gap - insert zeros
instead of "null" if you want another behaviour. This also holds for the start
and end of the chart. Note that stacking a mix of positive and negative values
in most instances doesn't make sense (so it looks weird).
Two or more series are stacked when their "stack" attribute is set to the same
key (which can be any number or string or just "true"). To specify the default
stack, you can set the stack option like this:
series: {
stack: null/false, true, or a key (number/string)
}
You can also specify it for a single series, like this:
$.plot( $("#placeholder"), [{
data: [ ... ],
stack: true
}])
The stacking order is determined by the order of the data series in the array
(later series end up on top of the previous).
Internally, the plugin modifies the datapoints in each series, adding an
offset to the y value. For line series, extra data points are inserted through
interpolation. If there's a second y value, it's also adjusted (e.g for bar
charts or filled areas).
