Hi,
I'm trying to make a scatter plot of 2 variables using a thirds as filter to
have different colors.
Let's say I have those data:
x=1,2,3,4
y=2,3,4,5
z=0,1,0,1
Then I want the values of x and y corresponding to those of z=0 to be of a
color and those corresponding to z=1 to be of another color.
This is the code I manage to do until know:
import xlrd
import numpy as np
import matplotlib.pyplot as plt
wb = xlrd.open_workbook('GBL2009.xls')
sh = wb.sheet_by_index(0)
def column_pos():
first_row=sh.row_values(0)
net_p=""
for i in first_row:
if i=='net_price':
net_p=first_row.index(i) #In gets the column position
for i in first_row:
if i=='material':
mat_p=first_row.index(i) #In gets the column position
for i in first_row:
if i=='qty':
qty_p=first_row.index(i) #In gets the column position
print net_p, mat_p, qty_p
#filtering(net_p, mat_p, qty_p)
test(net_p, mat_p, qty_p)
def test(net_p, mat_p, qty_p):
list=[]
for rownum in range(sh.nrows):
if sh.cell(rownum,mat_p).value in (96433890, 96433886):
list.append(sh.row_values(rownum))
x=[]
y=[]
z=[]
for i in list:
x.append(i[qty_p])
y.append(i[net_p])
z.append(i[mat_p])
fig = plt.figure(1, figsize=(5.5,5.5))
axScatter = plt.subplot(111)
colors = ('r', 'g', 'b', 'k')
for c in colors:
axScatter.scatter(x, y, c=c, marker='s')
plt.show()
