Help rendering a pylab plot

[cyberman]

Hi,

I'm just learning Python and I'm wondering if someone could help me get the chart to render properly in the following code, i.e. plot the sequence of data points. I have put print statements so I can see if the calculations are correct which they are.

Thanks

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24

from pylab import *   # Returns the summer tterature of seawater (in degrees Celsius) according to Mackenzie’s model. def some_function(ff, dd):     if dd >=0 and dd <=200:         tt = (22/-90)*ff+24     elif dd >=200 and dd <=1000:         st = (22/-90)*(ff)+24         gg = (st-2)/-800         tt = gg*dd+(gg*-1000+2)     else:         tt = 2.0     return tt   ff = float(25) for dd in range (0, 1200, 100):     tt1 = some_function(ff, dd)     plot(dd,tt1)     print(dd)     print(tt1) title("Something") xlabel("x label") ylabel("y label") show()

Just vectorize your function and plot it:

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23

from pylab import *    # Returns the summer tterature of seawater (in degrees Celsius) according to Mackenzie’s model. @np.vectorize def some_function(ff, dd):     if dd >=0 and dd <=200:         tt = (22/-90)*ff+24     elif dd >=200 and dd <=1000:         st = (22/-90)*(ff)+24         gg = (st-2)/-800         tt = gg*dd+(gg*-1000+2)     else:         tt = 2.0     return tt    ff = float(25) dd = np.arange(0, 1200, 100) tt1 = some_function(ff, dd) plot(dd,tt1) title("Something") xlabel("x label") ylabel("y label") show()
