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 example if the value was 0.10, the colour would be blue, or if 0.95,
the colour red.
Now the problem is I do not know how to access each individual grid
position, I guess I would have some form of counter system to count 0 -> 9
on the X axis and 0 -> 9 on the Y also.
Here is my pseudo code:
##########################################
Count1 = 0 ## For the X axis
Count2 = 0 ## For the Y axis
Max = 0 ## To count 0 - 99
ListValues = [0.11, 0.09, 0.34, 0.44, 0.29,.... all the way to 100 values]
while Max < 100:
if Count1 == 10:
Count2 = Count2 + 1 ## Increase the Y axis by one
Count1 = 0 ## If X axis counter = 10, reset it
to 0
else:
GridPosition = []
GridPosition.append(Count1)
GridPosition.append(Count2)
GridValue = ListValues[Max]
# Now armed with the GridPosition and GridValue, im stuck on
how to plot the square...
##########################################
So as you can see from above, I have the data ready to fill the relevant
grid position, just unsure on how to actually do it!
Just to clarify, this is a heatmap, so the GridValue should correspond to a
colour and fill that particular square with the colour from the colorbar
i.e.
levels = arange(0.0, 1.0, 0.025)
Thank you in advance for any help.
