Hi all,
I want to make a contout plot with a slider element. But I am not sure if it
is possible at all and if it is possible how.
The code is a mixture of two examples I found in the web. One part is the
slider example of matplotlib
> from pylab import *
>
> N = 50
> x = linspace(.0, 1.0, N)
> y = linspace(.0, 1.0, N)
> X, Y = meshgrid(x, y)
> Z = sin(X+16) - 2*cos(Y*5.2)
> c = contourf(X, Y, Z,20)
> colorbar()
>
> # Copied from the slider example ... not sure about the syntax
> axfreq = axes([0.25, 0.1, 0.65, 0.03])
> sfreq = Slider(axfreq, 'Amp', 0.1, 10.0, valinit=1)
> def update(val):
> global sfreq
> freq = sfreq.val
> Z = sin(freq*X+16) - 2*cos(Y*5.2)
> c.set_data(Z) # Is something like that possible
> draw()
> sfreq.on_changed(update)
> show()
>
I tried different stuff, but could not solve the problem. Perhaps anybody
has an idea to help me.
Thank you!
Best regards
Stefan
