I assume you are using the Windows OS and Python 3.2, simply do this ...
For PyQT download and run the Windows 32 bit self-extracting installer
PyQt-Py3.2-x86-gpl-4.8.3-1.exe
from http://www.riverbankcomputing.co.uk/.../pyqt/download
Py3.2 indicates that this the installer for Python 3.2, there are installers for other versions of Python too.
You can copy, click on (Toggle Plain Text) first, and paste the typical PyQT code below and run it from an IDE like IDLE that comes with your Python installation ...
# use PyQT to draw a simple vertical bar chart
# tested with PyQT4.8 and Python3.2
from PyQt4.QtCore import *
from PyQt4.QtGui import *
class BarChart(QWidget):
def __init__(self, data, parent=None):
# create the window (will be instance self)
QWidget.__init__(self, parent)
# setGeometry(x_pos, y_pos, width, height)
self.setGeometry(300, 300, 360, 320)
self.setWindowTitle('Simple Bar Chart')
self.data = data
def paintEvent(self, event):
painter = QPainter()
painter.begin(self)
# set color and width of line drawing pen
painter.setPen(QPen(Qt.black, 2))
# drawLine(x1, y1, x2, y2) from point (x1,y1) to (x2,y2)
# draw the baseline
painter.drawLine(20, 280, 340, 280)
# set up color and width of the bars
width = 20
painter.setPen(QPen(Qt.red, width))
delta = width + 5
x = 30
for y in self.data:
# correct for width
y1 = 280 - width/2
y2 = y1 - y + width/2
# draw each bar
painter.drawLine(x, y1, x, y2)
# add values to the top of each bar
s = str(y)
painter.drawText(x-8, y2-15, s)
x += delta
painter.end()
# data to be graphed
data = [30, 45, 80, 150, 220, 180, 110, 75, 50, 35, 20, 10]
app = QApplication([])
bc = BarChart(data)
bc.show()
app.exec_()
