Figure

MPLBaseNE
Base class for node wrapping the maptlotlib objects

MPLFigureNE
This node instanciates a Figure object and its FigureCanvasTkAgg object in its .canvas attribute.

MPLImageNE
This node creates a PIL image...

MPLDrawAreaNE
Class for configuring the axes.

MPLMergeTextNE
Class for writting multiple labels in the axes.Takes input from Text nodes.

MPLPlottingNode
Base class for plotting nodes

FillNE
plots filled polygons.

PolarAxesNE
This node plots on PolarAxes ...

StemNE
A stem plot plots vertical lines (using linefmt) at each x location from the baseline to y, and places a marker there using markerfmt.

MultiPlotNE
This node allows to plot multiple plots on same axes input: axes instances

TablePlotNE
Adds a table to the current axes and plots bars.

HistogramNE
This nodes takes a list of values and builds a histogram using matplotlib http://matplotlib.sourceforge.net/matplotlib.pylab.html#-hist Compute the histogram of x.

PlotNE
This nodes takes two lists of values and plots the the second against the first.

PlotDateNE
This nodes takes two lists of values and plots the the second against the first.

PieNE
plots a pie diagram for a list of numbers.

SpyNE
Plots the sparsity pattern of the matrix Z using plot markers.

Spy2NE
SPY2 plots the sparsity pattern of the matrix Z as an image...

VlineNE
Plots vertical lines at each x from ymin to ymax.

ScatterNE
plots a scatter diagram for two lists of numbers.

ScatterClassicNE
plots a scatter diagram for two lists of numbers.

FigImageNE
plots an image from a 2d array fo data...

PcolorMeshNE
This class is for making a pseudocolor plot.

PcolorNE
This class is for making a pseudocolor plot.

PcolorClassicNE
This class is for making a pseudocolor plot.

ContourNE
contour and contourf draw contour lines and filled contours.

SpecgramNE
plots a spectrogram of data in arraylistx.

CSDNE
plots a cross spectral density of data in arraylistx,arraylisty.

PSDNE
plots a cross spectral density of data in arraylistx.

LogCurveNE
This node is to make a loglog plot with log scaling on the x and y axis.

SemilogxNE
This node is to make a semilog plot with log scaling on the xaxis.

SemilogyNE
This node is to make a semilog plot with log scaling on the y axis.

BoxPlotNE
To plot a box and whisker plot for each column of x.

BarNE
Plots a horizontal bar plot with rectangles bounded by left, left+width, bottom, bottom+height (left, right, bottom and top edges) bottom, width, height, and left can be either scalars or sequences input: height - the heights (thicknesses) of the bars left - the x coordinates of the left edges of the bars Optional arguments: bottom - can be either scalars or sequences width - can be either scalars or sequences color - specifies the colors of the bars edgecolor - specifies the colors of the bar edges xerr - if not None, will be used to generate errorbars on the bar chart yerr - if not None, will be used to generate errorbars on the bar chart ecolor - specifies the color of any errorbar capsize - determines the length in points of the error bar caps align - 'edge' | 'center' 'edge' aligns the horizontal bars by their bottom edges in bottom, while 'center' interprets these values as the y coordinates of the bar centers.

BarHNE
Plots a horizontal bar plot with rectangles bounded by left, left+width, bottom, bottom+height (left, right, bottom and top edges) bottom, width, height, and left can be either scalars or sequences input: bottom - can be either scalars or sequences width - can be either scalars or sequences Optional arguments: height - the heights (thicknesses) of the bars left - the x coordinates of the left edges of the bars color - specifies the colors of the bars edgecolor - specifies the colors of the bar edges xerr - if not None, will be used to generate errorbars on the bar chart yerr - if not None, will be used to generate errorbars on the bar chart ecolor - specifies the color of any errorbar capsize - determines the length in points of the error bar caps align - 'edge' | 'center' 'edge' aligns the horizontal bars by their bottom edges in bottom, while 'center' interprets these values as the y coordinates of the bar centers.

QuiverNE
Makes a vector plot (U, V) with arrows on a grid (X, Y) If X and Y are not specified, U and V must be 2D arrays.

ErrorBarNE
Plot x versus y with error deltas in yerr and xerr.

RandNormDist
...

SinFunc
Outputs values describing a sinusoidal function.

SinFuncSerie
...

MatPlotLibOptions
This node allows to set various rendering Options.

NEMatPlotLibOptions

LegendNE
This nodes takes two lists of values and plots the the second against the first.

ColorBarNE
Class for drawing color bar input : plot - axes instance current_image -image instance extend - both,neither,min or max.If not 'neither', make pointed end(s) for out-of-range values.

Text
Class for writting text in the axes posx: x coordinate posy: y coordinate textlabel: label name rotation: angle to be rotated horizontal alignment: ['center', 'right', 'left'] vertical alignment: ['center', 'right', 'left']

SaveFig
Save the current figure.

MeshGrid
This class converts vectors x, y with lengths Nx=len(x) and Ny=len(y) to X, Y and returns them.

BivariateNormal
Bivariate gaussan distribution for equal shape X, Y
