\section{Math stuff}
|
||||
|

Cubic interpolation for one segment $[x_k, x_{k+1}]$ can be described as:
|
||||
|
||||
\begin{equation*}
|
||||
\begin{aligned}
|
||||
f(t) &= c_{oef1}t^3 + c_{oef2}t^2 + c_{oef3}t + c_{oef4} \hspace{1cm} with \\
|
||||
t(x) &= \frac{x - x_k}{x_{k+1} - x_k}
|
||||
\end{aligned}
|
||||
\end{equation*}
|
||||
|
||||
\hspace{1cm} and
|
||||
|
||||
\begin{equation*}
|
||||
\begin{aligned}
|
||||
c_{oef1} &= 2p_0 - 2p_1 - m_0 - m_1 \\
|
||||
c_{oef2} &= -3p_0 + 3p_1 - 2m_0 - m_1 \\
|
||||
c_{oef3} &= m_0 \\
|
||||
c_{oef4} &= p_0
|
||||
\end{aligned}
|
||||
\end{equation*}
|
||||
|
||||
|
||||
(see Wikipedia-Links below)\\
|
||||
\\
|
||||
If we rewrite this as function of $d = x - x_k$ we get
|
||||
|
||||
\begin{equation*}
|
||||
\begin{aligned}
|
||||
f'(d) &= c_{oef1}' d^3 + c_{oef2}' d^2 + c_{oef3}' d + c_{oef4}' \hspace{1cm} with \\
|
||||
c_{oef1}' &= \frac{c_{oef1}}{(x_{k+1} - x_k)^3} \\
|
||||
c_{oef2}' &= \frac{c_{oef2}}{(x_{k+1} - x_k)^2} \\
|
||||
c_{oef3}' &= \frac{c_{oef3}}{x_{k+1} - x_k} \\
|
||||
c_{oef4}' &= c_{oef4}
|
||||
\end{aligned}
|
||||
\end{equation*}
|
||||
\\
|
||||
The implemented algorithm uses two helper variables to calculate the coefficients of $f'$ efficiently:
|
||||
|
||||
\begin{equation*}
|
||||
\begin{aligned}
|
||||
common = m_k + m_{k+1} - 2 \frac{p_{k+1} - p_k}{x_{k+1} - x_k} \\
|
||||
invLength = \frac{1}{x_{k+1} - x_k}
|
||||
\end{aligned}
|
||||
\end{equation*}
|
||||
\\
|
||||
We use $p_0 = p_k$, $p_1 = p_{k+1}$, $m_0 = m_k (x_{k+1} - x_k)$, $m_1 = m_{k+1} (x_{k+1} - x_k)$ and $s = \frac{p_{k+1}-p_k}{x_{k+1}-x_k}$. The tangents are scaled with the length of the segment. \\
|
||||
\\
|
||||
If we insert this into the equations for the coefficients we get the formulas that are used in the algorithm:
|
||||
|
||||
\begin{equation*}
|
||||
\begin{aligned}
|
||||
c_{oef1}' &= \frac{c_{oef1}}{(x_{k+1} - x_k)^3} \\
|
||||
&= \frac{2p_0 - 2p_1 + m_0 + m_1}{(x_{k+1} - x_k)^3}\\
|
||||
&= (2p_k - 2p_{k+1} + m_k (x_{k+1} - x_k) + m_{k+1} (x_{k+1} - x_k) / (x_{k+1} - x_k)^3 \\
|
||||
&= \frac {(2p_k - 2p_{k+1} + m_k (x_{k+1} - x_k) + m_{k+1} (x_{k+1} - x_k)}{x_{k+1} - x_k} / (x_{k+1} - x_k)^2 \\
|
||||
&= (\frac {2p_k - 2p_{k+1}}{x_{k+1} - x_k} + m_k + m_{k+1} ) * invLength^2 \\
|
||||
&= (-2\frac {p_{k+1}- p_k}{x_{k+1} - x_k} + m_k + m_{k+1} ) * invLength^2 \\
|
||||
&= common * invLenght^2
|
||||
\end{aligned}
|
||||
\end{equation*}
|
||||
|
||||
\begin{equation*}
|
||||
\begin{aligned}
|
||||
c_{oef2}' &= \frac{c_{oef2}}{(x_{k+1} - x_k)^2} \\
|
||||
&= (-3p_0 + 3p_1 - 2m_0 - m_1) / (x_{k+1} - x_k)^2 \\
|
||||
&= (-3p_k + 3p_{k+1} - 2* m_k (x_{k+1} - x_k) - m_{k+1} (x_{k+1} - x_k)) / (x_{k+1} - x_k)^2 \\
|
||||
&= (\frac{-3p_k + 3p_{k+1}}{x_{k+1} - x_k} - 2m_k - m_{k+1}) * invLenght \\
|
||||
&= (3\frac{p_{k+1} - p_k}{x_{k+1} - x_k} - 2m_k - m_{k+1}) * invLenght \\
|
||||
&=(\frac{p_{k+1} - p_k}{x_{k+1} - x_k} + 2\frac{p_{k+1} - p_k}{x_{k+1} - x_k} - m_k - m_{k+1} - m_k) * invLenght \\
|
||||
&= (s - common - m_k) * invLenght
|
||||
\end{aligned}
|
||||
\end{equation*}
|
||||
|
||||
\begin{equation*}
|
||||
\begin{aligned}
|
||||
c_{oef3}' &= \frac{c_{oef3}}{x_{k+1} - x_k} \\
|
||||
&= \frac{m_0}{x_{k+1} - x_k} \\
|
||||
&= \frac{m_k (x_{k+1} - x_k)}{x_{k+1} - x_k} \\
|
||||
&= m_k
|
||||
\end{aligned}
|
||||
\end{equation*}
|
||||
|
||||
\begin{equation*}
|
||||
\begin{aligned}
|
||||
c_{oef4}' &= c_{oef4} = p_0 = p_k
|
||||
\end{aligned}

/* Flot plugin for adding the ability to pan and zoom the plot.
|
||||
|
||||
Copyright (c) 2007-2014 IOLA and Ole Laursen.
|
||||
Licensed under the MIT license.
|
||||
|
||||
The default behaviour is double click and scrollwheel up/down to zoom in, drag
|
||||
to pan. The plugin defines plot.zoom({ center }), plot.zoomOut() and
|
||||
plot.pan( offset ) so you easily can add custom controls. It also fires
|
||||
"plotpan" and "plotzoom" events, useful for synchronizing plots.
|
||||
|
||||
The plugin supports these options:
|
||||
|
||||
zoom: {
|
||||
interactive: false
|
||||
trigger: "dblclick" // or "click" for single click
|
||||
amount: 1.5 // 2 = 200% (zoom in), 0.5 = 50% (zoom out)
|
||||
}
|
||||
|
||||
pan: {
|
||||
interactive: false
|
||||
cursor: "move" // CSS mouse cursor value used when dragging, e.g. "pointer"
|
||||
frameRate: 20
|
||||
}
|
||||
|
||||
xaxis, yaxis, x2axis, y2axis: {
|
||||
zoomRange: null // or [ number, number ] (min range, max range) or false
|
||||
panRange: null // or [ number, number ] (min, max) or false
|
||||
}
|
||||
|
||||
"interactive" enables the built-in drag/click behaviour. If you enable
|
||||
interactive for pan, then you'll have a basic plot that supports moving
|
||||
around; the same for zoom.
|
||||
|
||||
"amount" specifies the default amount to zoom in (so 1.5 = 150%) relative to
|
||||
the current viewport.
|
||||
|
||||
"cursor" is a standard CSS mouse cursor string used for visual feedback to the
|
||||
user when dragging.
|
||||
|
||||
"frameRate" specifies the maximum number of times per second the plot will
|
||||
update itself while the user is panning around on it (set to null to disable
|
||||
intermediate pans, the plot will then not update until the mouse button is
|
||||
released).
|
||||
|
||||
"zoomRange" is the interval in which zooming can happen, e.g. with zoomRange:
|
||||
[1, 100] the zoom will never scale the axis so that the difference between min
|
||||
and max is smaller than 1 or larger than 100. You can set either end to null
|
||||
to ignore, e.g. [1, null]. If you set zoomRange to false, zooming on that axis
|
||||
will be disabled.
|
||||
|
||||
"panRange" confines the panning to stay within a range, e.g. with panRange:
|
||||
[-10, 20] panning stops at -10 in one end and at 20 in the other. Either can
|
||||
be null, e.g. [-10, null]. If you set panRange to false, panning on that axis
|
||||
will be disabled.
|
||||
|
||||
Example API usage:
|
||||
|
||||
plot = $.plot(...);
|
||||
|
||||
// zoom default amount in on the pixel ( 10, 20 )
|
||||
plot.zoom({ center: { left: 10, top: 20 } });
|
||||
|
||||
// zoom out again
|
||||
plot.zoomOut({ center: { left: 10, top: 20 } });
|
||||
|
||||
// zoom 200% in on the pixel (10, 20)
|
||||
plot.zoom({ amount: 2, center: { left: 10, top: 20 } });
|
||||
|
||||
// pan 100 pixels to the left and 20 down
|
||||
plot.pan({ left: -100, top: 20 })
|
||||
|
||||
Here, "center" specifies where the center of the zooming should happen. Note
|
||||
that this is defined in pixel space, not the space of the data points (you can
|
||||
use the p2c helpers on the axes in Flot to help you convert between these).
|
||||
|
||||
"amount" is the amount to zoom the viewport relative to the current range, so
|
||||
1 is 100% (i.e. no change), 1.5 is 150% (zoom in), 0.7 is 70% (zoom out). You
|
||||
can set the default in the options.

/* 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).

|

The plugin supports these options:
|
||||
|
||||
series: {
|
||||
threshold: {
|
||||
below: number
|
||||
color: colorspec
|
||||
}
|
||||
}
|
||||
|
||||
It can also be applied to a single series, like this:
|
||||
|
||||
$.plot( $("#placeholder"), [{
|
||||
data: [ ... ],
|
||||
threshold: { ... }
|
||||
}])
|
||||
|
||||
An array can be passed for multiple thresholding, like this:
|
||||
|
||||
threshold: [{
|
||||
below: number1
|
||||
color: color1
|
||||
},{
|
||||
below: number2
|
||||
color: color2
|
||||
}]
|
||||
|
||||
These multiple threshold objects can be passed in any order since they are
|
||||
sorted by the processing function.
|
||||
|
||||
The data points below "below" are drawn with the specified color. This makes
|
||||
it easy to mark points below 0, e.g. for budget data.
|
||||
|
||||
Internally, the plugin works by splitting the data into two series, above and
|
||||
below the threshold. The extra series below the threshold will have its label
|
||||
cleared and the special "originSeries" attribute set to the original series.
|
||||
You may need to check for this in hover events.
