Py-python only support python3 since the function dictionary paramaters in To leverage the power of Gnuplot, We develop pygnuplot demo 1: simple functionĢ.2 new developed member functions for python generated dataĢ.3 new developed global class-less function callĪs we know Gnuplot is a portable and powerful command-line driven graphing It’s easy to understandĪnd comply with both gnuplot and python’s grammer. With all the options as the function parameters. plot ( ' sin(x)', 'atan(x)', 'cos(atan(x))', key = 'fixed left top vertical Right noreverse enhanced autotitle box lt black linewidth 1.000 dashtype solid', style = 'increment default', samples = '50, 50', title = '"Simple Plots" font ",20" norotate' )įrom the example we can see, we plot the function with plot() function, Gnuplot ( terminal = 'pngcairo font "arial,10" fontscale 1.0 size 600, 400', output = '"simple.1.png"' ) g. Let’s see an exampleĪt first: #!/usr/bin/env python3 #coding=utf8 from pygnuplot import gnuplot g = gnuplot. To leverage the powful gnuplot to plot beautiful image inĮfficicent way in python, we port gnuplot to python. See set boxwidth, set errorbars, set style fill, and boxplot.Gnuplot is a portable command-line driven graphing utility for many Plot 'stat.dat' using 1:3:2:6:5 with candlesticks whiskerbars 0.5 # Plot with crossbars on the whiskers, crossbars are 50% of full width '' using 1:4:4:4:4 with candlesticks lt -1 notitle Plot 'stat.dat' using 1:3:2:6:5 with candlesticks title 'Quartiles', \ Note: To place additional symbols, such as the median value, on a box-and-whisker plot requires additional plot commands as in this example: # Data columns:X Min 1stQuartile Median 3rdQuartile Max If you set the fillstyle to solid or pattern, then this will be used for all boxes independent of open and close values. This is the behavior you will get if the current fillstyle is set to "empty". The usual convention for financial data is that the rectangle is empty if (open < close) and solid fill if (close < open). By default these whiskerbars extend the full horizontal width of the candlestick, but you can modify this by specifying a fraction of the full width. If you want crossbars, which are typically used for box-and-whisker plots, then add the keyword whiskerbars to the plot command. The width must be given in the same units as the x coordinate.Īn additional (6th, or 7th if the 6th column is used for width data) input column may be used to provide variable (per-datapoint) color information (see linecolor and rgbcolor variable).īy default the vertical line segments have no crossbars at the top and bottom. Īlternatively, an explicit width for each box-and-whiskers grouping may be specified in an optional 6th column of data. For backwards compatibility with earlier gnuplot versions, when the boxwidth parameter has not been set then the width of the candlestick rectangle is controlled by set errorbars. The width of the rectangle can be controlled by the set boxwidth command. Whisker plot: x box_min whisker_min whisker_high box_high The vertical line will be unchanged if the low and high prices are interchanged.įive columns of basic data are required: financial data: date open low high close A vertical line segment at the x coordinate extends up from the top of the rectangle to the high price and another down to the low. The symbol is a rectangular box, centered horizontally at the x coordinate and limited vertically by the opening and closing prices. The candlesticks style can be used for 2D data plotting of financial data or for generating box-and-whisker plots of statistical data.
