Hello,
I found the answer myself by reading more efficiently the doc :-( Sorry for
that...
Here is my working code :
def editFigurePyQtGraph(self):
# Mise en place
freq_lim = self.freq_lim
periodo_WK_module_lim = self.periodo_WK_module_lim
periodo_WK_phase_lim = self.periodo_WK_phase_lim
titre = self.titre
xlabel1 = self.xlabel1
xlabel2 = self.xlabel2
ylabel1 = self.ylabel1
ylabel2 = self.ylabel2
# Affichage du périodogramme d'interaction de WK
self.win = pg.GraphicsWindow()
self.win.resize(1100, 800)
self.win.ci.layout.setColumnFixedWidth(0, 1000)
self.win.ci.layout.setRowFixedHeight(0, 550)
self.win.ci.layout.setRowFixedHeight(1, 200)
PLOT1 = self.win.addPlot(title=titre, row=0, col=0)
if self.echel == 1:
PLOT1.plot(freq_lim, periodo_WK_module_lim, pen=pg.mkPen((255,
192, 0), width=2))
elif self.echel == 2:
PLOT1.plot(freq_lim, 20*np.log10(periodo_WK_module_lim),
pen=pg.mkPen((255, 192, 0), width=2))
PLOT1.setLabel("bottom", xlabel1)
PLOT1.setLabel("left", ylabel1)
PLOT1.showGrid(x=True, y=True)
PLOT1.showAxis("top", show=True)
PLOT1.getAxis("top").setStyle(showValues=False)
PLOT1.showAxis("right", show=True)
PLOT1.getAxis("right").setStyle(showValues=False)
PLOT1.showButtons()
PLOT2 = self.win.addPlot(row=1, col=0)
PLOT2.plot(freq_lim, periodo_WK_phase_lim, pen=pg.mkPen((255, 192,
0), width=2))
PLOT2.getAxis("left").setStyle(tickFont=QtGui.QFont('times'))
PLOT2.setLabel("left", ylabel2)
# Fonction pour afficher les radians
# en multiple de π
def format_left(base):
for i in range(-50, 51):
if np.isclose(0, i, 0, 1e-3):
ticks_setting[0].append((0, "0"))
else:
ticks_setting[0].append((i*base*np.pi, "{}
π".format(i*base)))
mini = int(np.floor(np.min(periodo_WK_phase_lim)/np.pi))
maxi = int(np.ceil(np.max(periodo_WK_phase_lim)/np.pi))
base = int(np.around((maxi-mini)/5, decimals=-1))
ticks_setting = [[]]
format_left(base)
# On affiche les radians en multiples entiers de π
PLOT2.getAxis("left").setTickSpacing(major=None, minor=base*np.pi)
PLOT2.getAxis("left").setTicks(ticks_setting)
PLOT2.showGrid(x=True, y=True)
PLOT2.showAxis("bottom", show=True)
PLOT2.getAxis("bottom").setStyle(showValues=False)
PLOT2.showAxis("top", show=True)
PLOT2.getViewBox().linkView(PLOT1.getViewBox().XAxis,
PLOT1.getViewBox())
PLOT2.showAxis("right", show=True)
PLOT2.getAxis("right").setStyle(showValues=False)
PLOT2.showButtons()
Hope that could help...
Regards
