PyQtgraph Y Axis Label Non Scientific Notation

PyQtgraph Y axis label is displaying in scientific notation. I do not want it to be in scientific notation. What is the code to change label to non scientific. Scientific notation

Solution 1:

PyQtgraph does not contain set_scientific(False). The best solution is to override the AxisItem.tickStrings will help to create custom labels.

Below is the code.

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

##### Override class #####
class NonScientific(pg.AxisItem):
    def __init__(self, *args, **kwargs):
        super(NonScientific, self).__init__(*args, **kwargs)

    def tickStrings(self, values, scale, spacing):
        return [int(value*1) for value in values] #This line return the NonScientific notation value

class MyApplication(QtGui.QApplication):
    def __init__(self, *args, **kwargs):

        self.win = pg.GraphicsWindow(title="Contour plotting")
        self.win.resize(1000,600)

        self.plot = self.win.addPlot(title='Contour', axisItems={'left': NonScientific(orientation='left')})
        self.curve = self.plot.plot()


    def PlotContour(self):
        x = range(50000,60000,10000)#X coordinates of contour
        y = range(500000,600000,100000)#Y coordinates of contour
        self.curve.setData(x=x, y=y)
        self.curve.autoRange()

def main():
    app = MyApplication(sys.argv)
    sys.exit(app.exec_())

if __name__ == '__main__':
    main()
