Is the following what you want? It has the x axis is on the left side,
labeled as the x axis and increases as you go up. The y axis is on the
bottom, is labeled the y axis and increases *to the left*.
Done by setting the plotwidget to have invertX=true which is actually a
property of the PlotItem created by the plotwidget. Then the graph is
rotated 90 degrees and the PlotItem axis's are labeled as you want.
from pyqtgraph.Qt import QtGui, QtCore
import numpy as np
import pyqtgraph as pg
app = QtGui.QApplication([])
mw = QtGui.QMainWindow()
win = pg.PlotWidget()
x = np.arange(0, 2*np.pi, 0.1)
y = np.sin(x)
l = pg.PlotDataItem(x=x,y=y)
win.addItem(l)
win.getPlotItem().invertX(True)
cw = QtGui.QWidget() # GENERIC WIDGET AS CENTRAL WIDGET (inside
main window)
lay = QtGui.QGridLayout()
cw.setLayout(lay)
lay.addWidget(win)
l.rotate(90)
ax = win.getPlotItem().getAxis('left')
ax.setLabel('Y')
ax = win.getPlotItem().getAxis('bottom')
ax.setLabel('X')
mw.setCentralWidget(cw)
mw.show()
if __name__ == '__main__':
import sys
if (sys.flags.interactive != 1) or not hasattr(QtCore, 'PYQT_VERSION'):
QtGui.QApplication.instance().exec_()
