Which multi-axes, multi-scale plotting tool to use?

Question

I am looking for plotting tools capable of using more than one or two vertical axes with different scales, like for instance:

alt text http://www.mathworks.com/matlabcentral/fx_files/9016/1/addaxis_screenshot.jpg

The goal is to plot several time series with different ranges in a same plot. For instance, I could have:

• Time series 1 with range [-1, 1]
• Time series 2 with range [-10, +10]
• Time series 3 with range [0, 1500]
• Time series 4 with range [0.5, 0.9]

Ideally I could plot each time series in its own axis with its own range, as shown in the image.

Which tools or libraries do you know that can do this?

Note: this question is related to this one, but I'm looking for more possibilities than Matlab.

Answer 1

You can do this in R. See this R-wiki page for an example.

This can also be very easy using the doubleYScale function, as in these examples.

Answer 2

Chaco can do this. See the following examples:

Multi-Y plot (placing multiple axes on a plot's frame): Source Screenshot of multiple y-axis plot http://www.enthought.com/~pwang/chaco/multi-y.png

Answer 3

According to the GNU plot, you can have upto 2 axii on GNU plot per chart.

Answer 4

Pretty sure you could do this in matplotlib

Failing that there are a lot of links on that wikipedia page for other plotting libraries.

Answer 5

matlab can do this

Answer 6

not sure if this what you want, but ZedGraph supports multiple axes. it's a .net component, so you'd have to write some code to get the data in there, but it's very easy to use.

Answer 7

MathGL can plot with multiple axis (see this sample). It is GPL (LGPL for core) library.
