matplotlib : Raster Plot
#1
Hey Everyone,

I am stuck at a point whee I need a simple python code generate a raster plot based on the values that is generated as the output of the dictionary.
The code for the dictionary is:


f = open('input.txt')
lines = f.readlines()
dict = {}
cnt = 1
for l in lines:
    ind = l[0]+l[2]+l[4]
    if ind not in dict:
        dict[ind] = cnt
        cnt = cnt + 1
sorted_dict = sorted(dict.items(), key=operator.itemgetter(1))
for t in sorted_dict:
    print(t)
The "input.txt" is 


Output:
0 0 0 0 1 1 65536000 0 0 0 1 1 1 32768000 0 0 0 2 1 1 32768000 0 0 1 0 3 1 65536000 0 1 1 0 2 1 32768000 0 2 1 0 2 2 32768000 0 0 2 0 3 2 -65536000 0 0 0 1 0 1 163840000 0 1 0 2 0 1 163840000 0 2 0 3 0 1 163840000 0 3 0 0 0 1 163840000
I need the first three columns alone. I need to remove repetition and number them in the order. For example, "0 0 0" becomes 1, "0 0 1" become 2, "0 1 1" becomes three. (In the same order as mentioned in the file)
Now, i need to plot a Raster Plot with the assigned numbers on my X axis and and the three digit value ("0 0 0", "0 0 1" and so on) as my Y axis.
Please help me guys..  Sad 
I have no idea of how to plot a raster!  Cry
