[FIXED] Plotting (x,y) point to point connections

Issue

I am trying to plot a point to point line plot in python. My data is in a pandas dataframe as below..

df = pd.DataFrame({
'x_coordinate': [0, 0, 0, 0, 1, 1,-1,-1,-2,0],
'y_coordinate': [0, 2, 1, 3,  3, 1,1,-2,2,-1],
})
print(df)

      x_coordinate  y_coordinate
   0             0             0
   1             0             2
   2             0             1
   3             0             3
   4             1             3
   5             1             1
   6            -1             1
   7            -1            -2
   8            -2             2
   9             0            -1

when I plot this, it is joining from point to point as in the order in the df.

df.plot('x_coordinate','y_coordinate')

But, is there a way, I can plot an order number next to it ? I mean the order it is travelling. Say 1 for the first connection from (0,0) to (0,2) and 2 from (0,2) to (0,1) and so on ?

Solution

I found an easier way to do it.. Thought to share..

fig, ax = plt.subplots()
df.plot('x_coordinate','y_coordinate',ax=ax)
for k, v in df[['x_coordinate','y_coordinate']].iterrows():
    ax.annotate('p'+str(k+1), v)
plt.show()
