Thanks.
The annotate function works. Does anybody knows a way to add some text
above or belove an arrow? Now I do it using text command and
coordinates for text. May be it possible to do directly with annotate
command?
Thanks.
Petro.
As far as I know, the 'arrow' function is not recommended. The 'annotate'
function has a lot more features. Here's your code with the annotate
function:
import pylab
from scipy import optimize
import numpy
x1=numpy.arange(-4000,1000,0.1)
x2=numpy.arange(-1000,4000,0.1)
y1=100*numpy.square(x1+1500)
Hi all
I want to draw an two headed arrow between two points.
But I get a line. What I am doing wrong? I actually try to plot an
image similar to this one:

may be I can use an annotate function for this.
Thanks
