Dear matplotlib users,
I have the following problem,
I need to plot an array of data as function of a parameter.
The example below will clarify what I mean.
The problem is that I don't know how to update the plot
# (this x,y are to simulate my actual data)
x=arange(100)
y=x**2
xc=50
xc_gt_0=where( (x>xc), x-xc, float('nan'))
pylab.plot(xc_gt_0,y)
pylab.show()
Now I want to see the same plot after having changed the value of xc
from the shell.
Any idea ?
I was thinking to something like this
while (reply =! "exit"):
xc=raw_input("Inser the new value")
draw()
but it doesn't work
Thanks in advance
marco

Save the output of the plot command as a line instance
line, = pylab.plot(something)
Then later update your xdata
xc = some_updated_data
Then set the xdata (or ydata or both) of the line instance
line.set_xdata(xc)
Then redraw your plot
pylab.draw()
That's it!
