[PYTHON] Draw a graph with Julia + PyQtGraph (1)

"Draw a graph in the programming language Julia" I succeeded in moving the sample for the time being, but the data created by my own program (in Julia language) I decided to find out how to draw a graph using. I made a graph of a simple function and a sample of arrow animation. As usual, the calculation result obtained by Julia is displayed as a graph in PyQtGraph. (Please create an environment and move it)

Note: For the environment construction, refer to "Drawing a graph in the programming language Julia".


jl:ArrowSample.jl(C:\julia-0.2.1-win32\Save to bin)

# -*- coding: utf-8 -*-

using PyCall

@pyimport ArrowSample
x  = [ -10 : 0.1 : 10 ]
y1 = [ x[i]*x[i] for i=1:length(x) ]
y2 = [ x[i]*2+50 for i=1:length(x) ]
ArrowSample.graph_run(x, y1, y2)

python:ArrowSample.py(C:\julia-0.2.1-win32\Save to bin)

# -*- coding: utf-8 -*-

from pyqtgraph.Qt import QtGui, QtCore
import pyqtgraph as pg

def graph_run(plot_data_x, plot_data_y1, plot_data_y2):

	app = QtGui.QApplication([])

	win = pg.GraphicsWindow(title=u"Julia+PyQtGraph sample")

	# Enable antialiasing for prettier plots

	p1 = win.addPlot(title=u"Arrow animation")
	c1 = p1.plot(x=plot_data_x, y=plot_data_y1)
	c2 = p1.plot(x=plot_data_x, y=plot_data_y2)
	p1.showGrid(x=True, y=True)
	a1 = pg.CurveArrow(c1)
	anim1 = a1.makeAnimation(loop=-1)
	a2 = pg.CurveArrow(c2)
	anim2 = a2.makeAnimation(loop=-1)
