Hi All,
The User of my program should use a slider element which lets compute
x,y and z and then my colorbar should also be updated with the new
computed x,y, and z values.
How to do this ?
There is a set_colorbar() method, but i dont know how to use it.
I also found a set_axes() method.
Here comes a clip of my code:
def drawhistogram(self,min,max):
if not hasattr(self, 'subplot3'):
self.subplot3 = self.figure.add_subplot(111)
self.subplot3.grid(True)
x,y,z = self.computehistogram(self.rastertime)
X,Y = meshgrid(x,y)
self.plots3 = self.subplot3.pcolor(X,Y,np.transpose(z))
self.figure.colorbar(self.plots3)
def repainthistogram(self,rastertime):
x,y,z = self.computehistogram(rastertime)
What for methods to use in my repainthistogram() method ?
regards Markus

If x,y don't change, and if you are not using masked arrays, then you might be able to add something like this:
self.plots3.set_array(np.transpose(z).ravel())
self.plots3.autoscale()
self.figure.canvas.draw()
The colorbar range will be updated automatically.
If x,y do change, then just clear the figure and regenerate it with the new data.
