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.
