Re: [Matplotlib-users] Multiple XY plots

[lkz2366]

Ok, I finally got it working after a couple of hours of experimenting.  I
couldn't figure out how to get your methods to work, maybe because I'm such
a novice at Python.  But, it was as easy as using a simple 'for' loop.


num = the number of lists to plot

time = a list of lists
volts = a list of lists


figure()
for x in range(0,num):
 plot(time[x],volt[x])
show()

Re: [Matplotlib-users] Multiple XY plots

Hi,

could you use a loop to solve it?

arr1list = [np.arange(10) + i for i in range(10)]
arr2list = [np.arange(10) -i for i in range(10)]

for arr1,arr2 in zip(arr1list,arr2list):
plot(arr1,arr2)

you can use a more object oriented way:

fig = plt.figure()
ax = fig.add_subplot()
for arr1,arr2 in zip(arr1list,arr2list):
ax.plot(arr1,arr2)

code not tested.

cheers,

Chao

 I am confused on how to plot a variable number of XY plots on a single
 chart.  I want to superimpose XY plots on a single chart but the number of
 plots is unknown until runtime.
 For example, if I want to plot 4 plots the code would be:
 figure()
 plot(x1,y1,x2,y2,x3,y3,x4,y4)
 show()

 But the number of plots is variable and could be anywhere from 5-30.  Any
 ideas on how I can do this?
 I already have the rest of my program working. The program reads all of
 the data from all of the files in a target directory and writes the data to
 X and Y lists.
 Thanks for any help.
