I have three parameters x , y and t . But the problem is my file structure.
My files are named as:
e_x_y.txt t_x_y.txt
where e_x_y.txt has the error for particular values of x and y and t_x_y.txt has corresponding time values.
I need to plot the values...

I can give you two: In order to do this, you will have to plot a series of x,y,t points and somehow represent the error.
The type of plot you are trying to make may be difficult to visualize well.

I've been experimenting with both GGPLOT2 and lattice to graph panels of data. I'm having a little trouble wrapping my mind around the GGPLOT2 model. In particular, how do I plot a scatter plot with two sets of data on each panel:
in Lattice I could do...

It looks like I can do this:
pg + geom_line(data=dd,aes(x_value, Actual_value,group=State_CD), colour="green")
is that a good way of doing things? It odd to me because... .
Well after posting the question I ran across this R Help thread that may have helped me .

Hi, I am trying to plot a series of 2D matrices containing ones and zeros (effectively black and white images) in matlab, which are ordered in 3D.
The code I have so far is:
function PlotthreeD() numrows = 100; numcols = 100; Plot1 = zeros(numcols); Plot...

The one thing you would have to be mindful of is this comment in the documentation:
The default shading is faceted , which colors each cell with a single color .
Investigate the Matlab function imagesc()
The function PCOLOR is one option .

How is possible to join dots of a scatter plot after plotting, and make a line from a dotted plot?

Answer Snippets (Read the full thread at stackoverflow):
I'm guessing you generated a scatter plot from x and y coordinates by,
plot(x,y,'.');
Join them with
plot(x,y,'.'); hold on; plot(x,y,'-');
Or in one command
plot(x,y,'.-');
Is this what you wanted?
If you have an existing....

I have the following code to plot one graphic:
plot(softmax(:,1), softmax(:,2), 'b.')
and then this one to plot another:
plot(softmaxretro(:,1), softmaxretro(:,2), 'r.')
Now I'd like to be able to plot both ones in the same place. How can I accomplish...

Answer Snippets (Read the full thread at stackoverflow):
You need to use the HOLD command so that the second plot is added to the first:
plot(softmax(:,1), softmax(:,2), 'b.'); hold on; plot(softmaxretro(:,1), softmaxretro(:,2), 'r.');
Solution#1: Draw both set of points on the same axes....

What are good python libraries which IronPython supports (current version wise) for drawing scientific plots on Win ? By "scientific plots" I mean simple x-y plots, x-y-z surface plots and x-y-z shaded plots.

Gnuplot can generate 3D charts - http://www.resolverhacks.net/gnuplot_plotting.html might be a starting ... .
Another way of running matplotlib.
Which will at least get you 2D plots.
According to this it's possible to use matplotlib with IronPython .

What Python plotting library do you recommend?
It should be noted the following considerations:
is it cross-OS? speed how clean it's interface? "prettyness" of the resulting plots License etc? In the Python Wiki there is a list , but there is little comparison...

Does anyone know of a free graph plotting app for windows (or online) that can plot something like this?

I'd like to suggest WolframAlpha....
Also, Spacetime (Win+Mac) looks promising.
If you had an Apple, the built-in Grapher would do the job .
I'd try Gnuplot or Octave / Matlab.
See Science: Math: Software: Graphing for a few dozens of plotting applications.

Mygraph.pdf", width = 11, height = 8 ) plot( x, y )
You can then divide up the space in the pdf several devices and plot different things to them, you can use dev.new(), dev.list(), and dev.next) There's a list of all of the devices here....
