# Instructions
#
# This program is probably not as efficient as I would like, but is relatively
# straightforward. First edit the legend labels then set the color levels. If
# you change the number of colors being used, you may need to edit a few values
# in the legend generator section.

import simpleSVG

b=simpleSVG.svg_class(fname="legend.svg",bbx=920,bby=610) # open file for your task

# create color bar

y = 10									# sets the vertical spacing between labels
basevalue = 1000						# largest labeled value

# SET LEGEND LABELS

values = ["more than 1,000,000", "750,000-1,000,000", "500,000-750,000", "250,000-500,000", "100,000-250,000", "50,000-100,000", "25,000-50,000", "10,000-25,000", "less than 10,000"]
level = values[0]

# SET COLORS

colors = ["#FFFFCC", "#FFEDA0", "#FED976", "#FEB24C", "#FD8D3C", "#FC4E2A", "#E31A1C", "#BD0026", "#800026"]	# color table to use

# LEGEND GENERATOR

for color in range(len(colors)):
	x = 625
	y = y + 31
	b.rect(x,y,30,30,fill=colors[-color-1])
	b.text(x+50,y+25,0,str(level),font_size="14pt",fill='black',text_anchor="left")
	if color < 8:
		level = values[color+1]
