This should work. It re-centers the graph on the location of the pointer when you scroll. import matplotlib.pyplot as plt def zoom_factory(ax,base_scale = 2.): def zoom_fun(event): # get the current x and y limits cur_xlim = ax.get_xlim() cur_ylim = ax.get_ylim() cur_xrange = (cur_xlim[1] – cur_xlim[0])*.5 cur_yrange = (cur_ylim[1] – cur_ylim[0])*.5 xdata = event.xdata # get … Read more
This effect may be easily achived with custom layout: class AnimatedManager extends Manager { int ANIMATION_NONE = 0; int ANIMATION_CROSS_FLY = 1; boolean mAnimationStart = false; Bitmap mBmpBNormal = Bitmap.getBitmapResource(“blue_normal.png”); Bitmap mBmpBFocused = Bitmap.getBitmapResource(“blue_focused.png”); Bitmap mBmpRNormal = Bitmap.getBitmapResource(“red_normal.png”); Bitmap mBmpRFocused = Bitmap.getBitmapResource(“red_focused.png”); Bitmap mBmpYNormal = Bitmap.getBitmapResource(“yellow_normal.png”); Bitmap mBmpYFocused = Bitmap.getBitmapResource(“yellow_focused.png”); Bitmap mBmpGNormal = Bitmap.getBitmapResource(“green_normal.png”); Bitmap … Read more

Fermin, Anthony +1. Thanks to all, you gave me the part of answer. My final solution: 1.Create or generate (free Ajax loading gif generator) animation and add it to project. 2.Create ResponseCallback interface (see Coderholic – Blackberry WebBitmapField) to receive thread execution result: public interface ResponseCallback { public void callback(String data); } 3.Create a class … Read more
