Hello, Does anyone know how I can set axis limits on a compass plot? Usually, using regular plot, you have the 'xlim' and 'ylim' options but there is nothing of that sort in compass plot. Perhaps there is a way to get access to the axis and set their limits? Thank you ... 10 Apr 2010 05:51

3-D data visualization question
Hello, I have a bit of a complex data set which I want to visualize. The data are of objects moving in 3-D space and I want to show the intensity of the time an object spent in each voxel. Specifically, my data are the following: Location at each moment in time is represented via its 3-d coordinates (x,y, and z vec... 23 Mar 2010 10:06

2 problems with subplot: empty space between graphs and grabbing entire figure
Hello, I was having this problem for some months. My specifics is that I have a development and a deployment machine. It was all good on the first, but on the second, it always came the 'UIW_SetUpGLPrinting' problem. The other rendereres (zbuffer and painters, as opposite to OpenGL) may not misbehave, but they... 23 Mar 2010 08:57

Issue when comparing precision between nested loop code and vectorized code
Hi all, Is anyone in the forum aware of any issues concerning the loss of precision when computing a matrix with a loop, as opposed to computing it with vectorized code? I vectorized a nested loop in my original code (Code 1 below) to make things run faster, but when I do the vectorization, it turns out that some... 23 Mar 2010 08:57
