Hi list,
I have a set of data with 3 columns :
x = x coordinate of the point
y = y coordinate
z = temperature
I can't see how to set a different color for each point function of
temperature value.
I have tried, which draw a colorfull beautiful map, the color varying
with the row rank of x (not what I want)
**
sqla=SELECT x, y, temperature FROM import_parcelle a WHERE
dat_loc=' + date_traite + ' AND code_uc=' + code_uc + ' ORDER BY
a.dateheure;
resa=db.query(sqla)
data=resa.dictresult()
x= [float(a[x]) for a in data] # -- extraction de la colonne x
y= [float(a[y]) for a in data] # -- extraction de la colonne y
z= [float(a[temperature]) for a in data] # -- extraction de la
colonne temperature
scatter(x, y, c=arange(len(x)), cmap=cm.spring)
title(Carte des temperatures(L/min))
xlim(min(x)-10,max(x)+10)
ylim(min(y)-10,max(y)+10)
**
What is the good way to do what I reach for ?
I have much trouble to know how to define the c parameter of scatter. I
saw the arrange thing somewhere in internet, but don't understand what
it is for.
Thanks in advance for your help.
Michael
