Ok the last one got garbled.
My apologies to the list but here is another go.
Hi Thomas,
I posted via nabble. It looks like something stripped the code.
Here is the bit where the axes are set up
def setup_axes(self, fig, rect):
"""
With custom locator and formatter.
Note that the extreme values are swapped.
"""
transform = PolarAxes.PolarTransform()
angle_ticks = [(0, r"$Right$"),
(.5*pi, r"$Forward$"),
(pi, r"$Left$")]
grid_locator1 = FixedLocator([v for v, s in angle_ticks])
tick_formatter1 = DictFormatter(dict(angle_ticks))
grid_locator2 = MaxNLocator(4)
self.grid_helper = floating_axes.GridHelperCurveLinear(transform,
extremes=(0, pi,
self.sonar_limit, 0),
grid_locator1=grid_locator1,
grid_locator2=grid_locator2,
tick_formatter1=tick_formatter1,
tick_formatter2=None,
)
self.axes = floating_axes.FloatingSubplot(fig, rect,
grid_helper=self.grid_helper)
self.axes.axis["bottom"].major_ticklabels.set_rotation(180)
self.axes.axis["left"].set_axis_direction("bottom")
self.axes.grid(b=True, which='major', color='b', linestyle='-')
fig.add_subplot(self.axes)
# create a parasite axes whose transData in RA, cz
self.auxiliary_axes = self.axes.get_aux_axes(transform)
self.auxiliary_axes.patch = self.axes.patch # for auxiliary_axis to
have a clip path as in ax
self.axes.patch.zorder=0.9 # but this has a side effect that the
patch is
# drawn twice, and possibly over some other
# artists. So, we decrease the zorder a bit to
# prevent this.
self.lines, = self.auxiliary_axes.plot(self.theta, self.radius)
and here is the bit where the plot is updated
def idleCallback(self):
global root
plotit = False
logging.debug('Acquire the data lock')
self.dataLock.acquire()
if self.newSonarDataAvailable:
plotit = True
theta = self.theta[:]
radius = self.radius[:]
selfNewSonarDataAvailable = False
self.dataLock.release()
# theta.insert(0, 0.)
# theta.append(0.)
# radius.insert(0, 0.)
# radius.append(0.)
if plotit:
logging.debug('Plotting')
self.lines.set_data(theta, radius)
self.axes.relim()
self.axes.autoscale_view()
self.canvas.draw()
if have also put the full code file here

As you can see I have been trying a few other things. Looks like if am
missing the boat pretty comprehensively!
