I'm trying to plot a series of points/locations on a map. I'm reading the
latitudes and longitudes from a file, with each lat, lon pair on each record
(line). Here is the code:
def make_float(line):
lati, longi = line.split()
return float(lati), float(longi)
my_dict = {}
with open("file.txt") as f:
for item in f:
lati,longi = make_float(item)
my_dict[lati] = longi
xpt,ypt = m(-76.1670,39.4670 )
plt.text(xpt,ypt,'1',color='white')
#print my_dict
The matplotlib code which I've previously used to plot a single point on the
map is below, with longitude and latitude in ( ):
xpt,ypt = m(-70.758392,42.960445)
plt.text(xpt,ypt,'1',color='white')
When replacing (-70.758392,42.960445) with (longi,lati), the code plots only a
single '1' at the location of just the last coordinate pair in the file. So now
I only need to plot them all. Does the code I've implemented have an implicit
loop to it?
