problems with autoscale_view

Community matplotlib-users

Thank you, now are plt.text in the coordinates. Unfortunately, now overlapping the x and y coordinates.

How is it possible to solve this problem?

Thank you, but unfortunately I have still the same problems:
* plt.text appears outside x and y coordinates
* and the coordinates starts not from 0

with the updated code:
from pylab import *
import matplotlib.pyplot as plt

x = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19,
20, 21, 22, 23, 24, 25, 26, 27, 28, 29]
y1 = [20, 24, 8, 4, 12, 22, 31, 25, 15, 28, 12, 27, 22, 22, 27, 14, 32,
28, 8, 17, 2, 8, 29, 13, 14, 20, 11, 28, 8]
y2= [2, 32, 28, 1, 22, 11, 14, 27, 3, 31, 12, 20, 32, 24, 24, 16, 7, 10,
12, 11, 3, 32, 10, 20, 14, 14, 3, 25, 14]
point_labels1 = ['A=1', 'A=1', 'A=1', 'A=1', 'A=1', 'A=1', 'A=1', 'A=1',
'A=1', 'A=1', 'A=1', 'A=1', 'A=1', 'A=1', 'A=1', 'A=1', 'A=1', 'A=1',
'A=1']
point_labels2 = ['B=1', 'B=1', 'B=1', 'B=1', 'B=1', 'B=1', 'B=1', 'B=1',
'B=1', 'B=1', 'B=1', 'B=1', 'B=1', 'B=1', 'B=1', 'B=1', 'B=1', 'B=1',
'B=1']

fig = plt.figure()
ax = fig.add_subplot(111)

ax.set_title('The red point should be on the path')

plt.plot(x, y1, 'bo', x, y2, 'go')
ax.grid(True)
maxy = max(max(y1), max(y2))
maxx = max(x)

ax.set_xlim((0.0, maxx))
ax.set_ylim((0.0, maxy))

fig.autofmt_xdate()

plt.xticks(range(0, 40, 1))

plt.yticks(range(0, 40, 1))
plt.xlabel('Longitude')
plt.ylabel('Latitude')
plt.legend(('Model length', 'Data length'),
            'best', shadow=True, fancybox=True)

for i, label in enumerate(y1):
   plt.text (x[i], y1[i]+0.2, label,
             horizontalalignment='center' )

for i, label in enumerate(y2):
   plt.text (x[i], y2[i]+0.2, label,
             horizontalalignment='center' )

ax.autoscale_view()
plt.savefig('test.png')
plt.show()

What did I wrong?

Like Eric said, the call to ax.autoscale_view() overrides the limits
you set by hand. Remove this line.

I am not sure I understand what you mean. Could you please attach an image of the problem?

Just make the axes limits a little larger than the range of your data (instead of exactly equal to the range). That way your labels will fit.
