+____________________________________________________
+
+ what it is:
+ ____________________________________________________
+
+ curvedLines is a plugin for flot, that tries to display lines in a smoother way.
+ This is achieved through adding of more data points. The plugin is a data processor and can thus be used
+ in combination with standard line / point rendering options.
+
+ => 1) with large data sets you may get trouble
+ => 2) if you want to display the points too, you have to plot them as 2nd data series over the lines
+ => 3) consecutive x data points are not allowed to have the same value
+
+ Feel free to further improve the code
+
+ ____________________________________________________
+
+ how to use it:
+ ____________________________________________________
+
+ var d1 = [[5,5],[7,3],[9,12]];
+
+ var options = { series: { curvedLines: {  active: true }}};
+
+ $.plot($("#placeholder"), [{data: d1, lines: { show: true}, curvedLines: {apply: true}}], options);
+
+ _____________________________________________________
+
+ options:
+ _____________________________________________________
+
+ active:           bool true => plugin can be used
+ apply:            bool true => series will be drawn as curved line
+ monotonicFit:	   bool true => uses monotone cubic interpolation (preserve monotonicity)
+ tension:          int          defines the tension parameter of the hermite spline interpolation (no effect if monotonicFit is set)
+ nrSplinePoints:   int 			defines the number of sample points (of the spline) in between two consecutive points
+
+ deprecated options from flot prior to 1.0.0:
+ ------------------------------------------------
+ legacyOverride	   bool true => use old default
+    OR
+ legacyOverride    optionArray
+ {
+ 	fit: 	             bool true => forces the max,mins of the curve to be on the datapoints
+ 	curvePointFactor	 int  		  defines how many "virtual" points are used per "real" data point to
+ 									  emulate the curvedLines (points total = real points * curvePointFactor)
+ 	fitPointDist: 	     int  		  defines the x axis distance of the additional two points that are used
+ }						   		   	  to enforce the min max condition.
+ */

+/*
+ *  v0.1   initial commit
+ *  v0.15  negative values should work now (outcommented a negative -> 0 hook hope it does no harm)
+ *  v0.2   added fill option (thanks to monemihir) and multi axis support (thanks to soewono effendi)
+ *  v0.3   improved saddle handling and added basic handling of Dates
+ *  v0.4   rewritten fill option (thomas ritou) mostly from original flot code (now fill between points rather than to graph bottom), corrected fill Opacity bug
+ *  v0.5   rewritten instead of implementing a own draw function CurvedLines is now based on the processDatapoints flot hook (credits go to thomas ritou).
+ * 		   This change breakes existing code however CurvedLines are now just many tiny straight lines to flot and therefore all flot lines options (like gradient fill,
+ * 	       shadow) are now supported out of the box
+ *  v0.6   flot 0.8 compatibility and some bug fixes
+ *  v0.6.x changed versioning schema
+ *
+ *  v1.0.0 API Break marked existing implementation/options as deprecated
+ *  v1.1.0 added the new curved line calculations based on hermite splines
+ *  v1.1.1 added a rough parameter check to make sure the new options are used

+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} \\

+<h4>CurvedLines: customizing and mixing</h4>
+
+<div class="text-block"> <span id="hoverText">point at: - / -</span>
+
+</div>
+<div id="flotContainer" class="chart-style"></div>
+<div class="text-block">The example shows two datasets (d1, d2) plotted using different styles (curved line, points, bigger points). The points are hoverable, the curved line is not.</div>
+<div class="text-block">To achieve such mixed plots you have to define some settings on a per series level. In the example the curved line plugin is generally set to active (as default in the options object) but will be applied only to the first series. Similarly hovering is deactivated for the first series. The combination of "replotting" (series 1 and 2 both origin form dataset d1) and per series settings allows you to mix different plotting styles and settings in one canvas.</div>
