I have a script that produces real time data, is it possible to plot all of this data and show a moving curve as data is acquired using matplotlib?
Matplotlib supports animations. The easiest is to look at some of the examples.

I am trying to plot 2D bars in a Plotly 3D figure. I understand that Plotly's 3D figures do not yet support bar charts out of the box, but I have come across some examples from other people on the Plotly forums which have shown how this might be achieved.
Please see the post Adding a shape to a 3D plot. This is close to what I am trying to achieve, but I am not trying to plot a histogram.
It appears plotting traces as a mesh3d, adding in the missing points and triangulating is the way to go for Plotly's 3D chart, according to other examples I have seen. Below is an example of what I am looking for that I created using Matplotlib.
As you can see, x axis is the date, y axis is the trace name and z axis is the value. I would like to see if I can achieve something similar using Plotly's 3D charts, which are so much better of course because of the client side interactivity.
Is there a working example for what I'm trying to achieve? I am simply looking to plot simple (date, value) per trace as 2D bars in the 3D figure.
There isn't any current way to have a bar chart in 3D with Plotly (at least that I am aware of).
Documentation: Plotly Python Open Source Graphing Library 3D Charts
As shown in the documentation, there aren’t any options for a bar chart. There are, however, alternatives like a bubble chart.
I'm trying to visualize frequency of imported from reports items in array using Python. I'm new to drawing graphs, so how to do it, using any module?
To draw graphs in python you need to do the following,
import matplotlib as plt
plt.plot(array_1,array_2)
plt.show()
I highly recommend checking out this Matplotlib Docs
I have an array of points (x,y,z) that I would like to animate in 3D using Mayavi (Python). I am currently using a Plot3D command to plot all of the points simultaneously (modeling the movement of a particle), but would love some help on the animation.
Thanks!
Matplotlib offers a lot of possibilities for animation. Have a look at the specific routines for animation. In particular, there's a specific example for 3D plotting.
There are quite a few tutorials on the 'web. Eg. Matplotlib Animation Tutorial and Animated 3-D Plots in Python
I'm preparing a set of reports using open source ReportLab. The reports contain a number of charts. Everything works well so far.
I've been asked to take a (working) bar chart that shows two series of data and overlay a fitted curve for each series.
I can see how I could overlay a segmented line on the bar graph by creating both a line chart and bar chart in the same ReportLab drawing. I can't find any reference for fitted curves in ReportLab, however.
Does anyone have any insight into plotting a fitted curve to a series of data in ReportLab or, failing that, a suggestion about how to accomplish this task (I'm thinking that chart would need to be produced in matplotlib instead)?
I would recommend using MatPlotLib. This is exactly the sort of thing it's designed to handle and it will be much easier than trying to piece together something in ReportLab alone, especially since you'll have to do all the calculation of the line on your own and figure out the details of how to draw it in just the right place. MatPlotLib integrates easily with ReportLab; I've used the combination several times with great results.
I would like to plot multiple pie charts over an existing plot using absolute coordinates.
I went through the add_axes method and also the AxesGrid toolikt but couldn't find a solution.
To be more specific, I want to draw pie charts over a geographical map using the basemap module.
This tutorial explains how to use matplotlib Basemap for drawing pie charts on a map. It is fairly simple and gives code examples.
