Hi,
I have some multi-dimensional data which I slice in four plot windows. I
link the required axes manually by connecting to a signal emitted by a
ViewBox when its range is changed.
Code snippet below, hopefully will get you on track.
# Link axes of plots
self.overview.setYLink(self.t1slice)
self.overview.setXLink(self.t2slice)
self.t1slice.getViewBox().sigRangeChangedManually.connect(self.
_link_waxes_t1slice)
self.t2slice.getViewBox().sigRangeChangedManually.connect(self.
_link_waxes_t2slice)
self.spectrum.getViewBox().sigRangeChangedManually.connect(self.
_link_waxes_spectrum)
# Slot functions to react and change range of linked plots
def _link_waxes_t1slice(self, something):
self.t2slice.setYRange(*self.t1slice.getViewBox().viewRange()[0])
self.spectrum.setXRange(*self.t1slice.getViewBox().viewRange()[0])
def _link_waxes_t2slice(self, something):
self.t1slice.setXRange(*self.t2slice.getViewBox().viewRange()[1])
self.spectrum.setXRange(*self.t2slice.getViewBox().viewRange()[1])
def _link_waxes_spectrum(self, something):
self.t1slice.setXRange(*self.spectrum.getViewBox().viewRange()[0])
self.t2slice.setYRange(*self.spectrum.getViewBox().viewRange()[0])
