      given a touch point in the view space, compute the corresponding point in data coords. assumes linear scaling!
      TODO: support log scaling 
      
      there are basically two bbox transforms:  1) from figure coords to view coords, accounting for sign change in y. this then lets us compute axes box in view coords, and generate 2) transform from view to data coords.

      '''
      transFig=BboxTransformTo(Bbox([(0,self.height),(self.width,0)]))
      bbox_axes=Bbox(transFig.transform(plt.gca().get_position()))
      bbox_data=Bbox([(self.xlim[0],self.ylim[0]),(self.xlim[1],self.ylim[1])])
      transMPL=BboxTransform(bbox_axes,bbox_data)
      self.trans=transMPL
      ax_pt=transMPL.transform_point(point_px)      
      return ax_pt
