Plots with scientific notation on the ylabel appear smaller than other
plots in a GraphicsLayoutWidget after using setData.
In the example below, the width of the first column shrinks after setting
the data in each plot.
from pyqtgraph.Qt import QtGui, QtCore
import pyqtgraph as pg
import random
app = QtGui.QApplication([])
# create layout and add 4 plots to it in 2x2 grid
win = pg.GraphicsLayoutWidget(show=True)
win.showMaximized()
plots = []
for i in range(2):
for j in range(2):
plots.append(win.addPlot())
win.nextRow()
# create plotdataitem for each plot
lines = [p.plot() for p in plots]
# add random data, with 1 plot much larger range than the rest
def update():
lines[0].setData(range(100), [random.gauss(1e7, 1e5) for i in
range(100)])
for line in lines[1:4]:
line.setData(range(100), [random.gauss(0, 1) for i in range(100)])
# update()
timer = QtCore.QTimer()
timer.timeout.connect(update)
timer.start(2000)
app.exec_()
