Does Matlab execute a callback when a plot is zoomed/resized/redrawn? -

-

in matlab, update data plotted in set of axes when user zooms plot window. example, suppose want plot particular function defined analytically. update plot window additional data when user zooms traces, can examine function arbitrary resolution.

does matlab provide hooks update data when view changes? (or when redrawn?)

yes, does. zoom mode object has following callbacks:

buttondownfilter actionprecallback actionpostcallback

the latter 2 executed either before or after zoom function. set update function in actionpostcallback, you'd update plot according new axes limits (the handle axes passed second input argument callback).

i want make logharitmic fit. keep getting runtime error: optimal parameters not found: number of calls function has reached maxfev = 1000 i use following script. can tell me go wrong? use spyder still beginner. import math import matplotlib mpl scipy.optimize import curve_fit import numpy np #data f1=[735.0,696.0,690.0,683.0,680.0,678.0,679.0,675.0,671.0,669.0,668.0,664.0,664.0] t1=[1,90000.0,178200.0,421200.0,505800.0,592200.0,768600.0,1036800.0,1371600.0,1630800.0,1715400.0,2345400.0,2409012.0] f1n=np.array(f1) t1n=np.array(t1) plt.plot(t1,f1,'ro',label="original data") # curvefit def func(t,a,b): return a+b*np.log(t) t=np.linspace(0,3600*24*28,13) popt, pcov = curve_fit(func, t, f1n, maxfev=1000) plt.plot(t, func(t, *popt), label="fitted curve") plt.legend(loc='upper left') plt.show() your original data t1 , f1 . therefore curve_fit should given t1 second argument, not t . popt, pcov = curve_fit(func,
