ax.plot_date((dates, dates), (highs, lows), '-')
I'm currently using this command to plot financial highs and lows using Matplotlib. It works great, but how do I remove the blank spaces in the x-axis left by days without market data, such as weekends an...

Say I have a list of datetimes, and we know each datetime to be the recorded time of an event happening.
Is it possible in matplotlib to graph the frequency of this event occurring over time, showing this data in a cumulative graph (so that each point is...
I'd like to plot a normalized histogram from a vector using matplotlib. I tried the following:
plt.hist(myarray, normed=True)
as well as:
plt.hist(myarray, normed=1)
but neither option produces a y-axis from [0, 1] such that the bar heights of the ...

In Python 2.6, I used matplotlib to make some simple graphs. However, it is incompatible with Python 3.1.
What are some alternative modules that can accomplish the same thing without being very complex?
I created a very simple scatter plot using pylab.
pylab.scatter(engineSize, fuelMile)
pylab.show()
The rest of the program isn't worth posting, because it's that line that's giving me the problem. When I change "scatter" to "plot" it graphs the data, b...
I am trying to create a bar graph using the matplot library but I cant figure out what the arguments are for the function.
The documentation says bar(left, height), but I don't know how to put in my data [which is a list of numbers called x] in here.
I...
I'm writing a python application that will make heavy use of a graph data structure. Nothing horribly complex, but I'm thinking some sort of graph/graph-algorithms library would help me out. I've googled around, but I don't find anything that particularly...
I'm trying to create a histogram with argument normed=1
For instance:
import pylab
data = ([1,1,2,3,3,3,3,3,4,5.1])
pylab.hist(data, normed=1)
pylab.show()
I expected that the sum of the bins would be 1. But instead, one of the bin is bigger then...
I have an array of timestamps in the format (HH:MM:SS.mmmmmm) and another array of floating point numbers, each corresponding to a value in the timestamp array.

If I make a graph using pylab from matlotlib like so...
import pylab as p
x = [0,1,2]
y = [2,4,6]
p.plot(x,y)
p.show()
I want to use the p.text function to add text to the graph. However, I want to put the text in the margin outside of the data window...
I would like to draw a standard 2D line graph with pylot, but force the axes' values to be between 0 and 600 on the x, and 10k and 20k on the y. Let me go with an example...
