Good day! Could You please tell me how can I get axises autoscaling in the animated plot example. I've take an example and have modifyed it slightly so the second line in plot gets out of bounding box during animation. What I need is autoscaling of axises during animation. Please point mee what I have to do.
Thanks a lot! Hereafter a modifyed example: -------------------------------------------------------------------- # For detailed comments on animation and the techniqes used here, see # the wiki entry http://www.scipy.org/Cookbook/Matplotlib/Animations import sys from matplotlib.figure import Figure from matplotlib.backends.backend_qt4agg import FigureCanvasQTAgg as FigureCanvas from PyQt4 import QtGui ITERS = 100 import numpy as np import time class BlitQT(FigureCanvas): def __init__(self): FigureCanvas.__init__(self, Figure()) self.ax = self.figure.add_subplot(111) self.ax.grid() self.draw() self.old_size = self.ax.bbox.width, self.ax.bbox.height self.ax_background = self.copy_from_bbox(self.ax.bbox) self.cnt = 0 self.x = np.arange(0,2*np.pi,0.01) self.sin_line, = self.ax.plot(self.x, np.sin(self.x), animated=True) self.cos_line, = self.ax.plot(self.x, np.cos(self.x), animated=True) self.draw() self.tstart = time.time() self.startTimer(10) def timerEvent(self, evt): current_size = self.ax.bbox.width, self.ax.bbox.height if self.old_size != current_size: self.old_size = current_size self.ax.clear() self.ax.grid() self.draw() self.ax_background = self.copy_from_bbox(self.ax.bbox) self.restore_region(self.ax_background, bbox=self.ax.bbox) # update the data self.sin_line.set_ydata(np.sin(self.x+self.cnt/10.0)) self.cos_line.set_ydata((self.x+self.cnt)/50.0) # just draw the animated artist self.ax.draw_artist(self.sin_line) self.ax.draw_artist(self.cos_line) # just redraw the axes rectangle self.blit(self.ax.bbox) if self.cnt == 0: # TODO: this shouldn't be necessary, but if it is excluded the # canvas outside the axes is not initially painted. self.draw() if self.cnt==ITERS: # print the timing info and quit print 'FPS:' , ITERS/(time.time()-self.tstart) sys.exit() else: self.cnt += 1 app = QtGui.QApplication(sys.argv) widget = BlitQT() widget.show() sys.exit(app.exec_()) ------------------------------------------------------------------------------ This SF.net email is sponsored by Sprint What will you do first with EVO, the first 4G phone?
