Since you are using Python, you can just ask it:
>>> import numpy as np
>>> help(np.random.rand)
Help on built-in function rand:
rand(...)
Return an array of t
AH HA!
Pete, you are a life saver! Thank you so much for all your help !

try this:
list = numpy.array([0.66877509, 0.58785363, 0.32387598, 0.16877509,
0.48785363,

Thanks again Pete for your help.
I have numpy imported, and here is what my code looks like:
import matplotlib
import numpy
from numpy import *
from pylab import *
list = [0.66877509, 0.58785363, 0.32387598, 0.16877509, 0.48785363,
0.22387598, 0.96877509, 0.18785363
rand() produces a numpy array, so long as numpy is imported into the
namespace.
I was simply using the random numbers as example data.
In your case you would take your 1x100 vector of heat data and re-shape it
to a 10x10 array. data=data.reshape(10,10)

Hi Pete / All,
Thank you for the help so far, really appreciate it.
I have managed to plot the graph above using the code you gave me:
###
z=rand(3,3)
pcolormesh(z)
colorbar()
savefig('colour.png')
###
However, I am trying to find out what rand() actually does
That looks perfect, how did you do it?
Thanks

Hi Pete,
Thanks for the quick response.
Will imshow() actually plot the graph?
Do I not need to do something like:
contourf(X, Y, Z, levels)
Thanks

Someone more knowlegeable than me may corrct me here, but the code for
getting your data into a grid could be greatly simplified to:
X = array([0,1,2,3,4,5,6,7,8,9,])
Y = array([0,1,2,3,4,5,6,7,8,9,])
Z = ListValues.reshape(10,10)
than you could use something like imshow() to show the data withou
Hi,
I have been using matplotlib for about 2 weeks now. I thought it would be
good to try plotting heatmaps to show some data.
The idea:
I have 100 values all ranging from 0.00 to 1.00, I would like to create a
graph with a 10 by 10 grid. Therefore each value has 1 section of the grid.
So, for
11 matches
