PS: I thought I would probably give a better example
In a directory I have these files:
2537.dat
5043.dat
5075.dat
7581.dat
1.009e+04.dat
1.551e+04.dat
1.805e+04.dat
2.056e+04.dat
4.955e+04.dat
5.209e+04.dat
5.459e+04.dat
5.462e+04.dat
1.445e+05.dat
1.47e+05.dat
5.016e+05.dat
5.041e+05.dat
5.067e+05.dat
5.171e+05.dat
5.196e+05.dat
5.511e+05.dat
5.537e+05.dat
5.562e+05.dat
8.842e+05.dat
1.465e+06.dat
I would like to plot them with matplotlib like this:
-----------------------------------------------------------
X = cluster[:, 1] # Column 2
Y = cluster[:, 2] # Column 3
M = cluster[:, 4] # Column 5
Radius = log(M)
ylabel ('Y (pc)', size=18)
scatter(X, Y, s=Radius,\
marker='o', color='red',\
edgecolors='black',\
alpha=0.9,antialiased=True)
xlabel ('X (pc)', size=18)
-----------------------------------------------------------
where
"cluster" runs from the first data file to the last one and
"color" changes from one data file to the next one
The goal is to have all the data files plotted in a single graph
How could I do this?
Thanks a lot
P.
