    plotting multimensional functions. Softa?

    Hello

    I need a software to plot multimensional data.
    Which one is good?. Most of them are restricted to 3D graphs.

    I couldn't find any good link explaining the different methods used to plot multimensional graphics (such as using the 3 cartesian axis and different colours for the 4th variable)

    MATLAB Central - File detail - Surface Curvature

    Here is an example of using matlab to plot 4D data. The Fourth dimension (in colour) is the curvature of the surface at that partcular (x,y,z) point. Hope this helps.

    This is done using MATLAB's "surf" function.
    Code:
    EDU>> help surf
     SURF   3-D colored surface.
        SURF(X,Y,Z,C) plots the colored parametric surface defined by
        four matrix arguments.  The view point is specified by VIEW.
        The axis labels are determined by the range of X, Y and Z,
        or by the current setting of AXIS.  The color scaling is determined
        by the range of C, or by the current setting of CAXIS.  The scaled
        color values are used as indices into the current COLORMAP.
        The shading model is set by SHADING.

    What sort of data are your trying to visualize? x y z data and temperature for example?

    I'm using several programs in order to optimize functions with many parameters (from 3 to 10).
    That functions work with series of data (discrete).
    The result of that programs are a spreadsheet with one column of data for each parameter and another one one for the function.
    Some of that programs offer you the possibility of generating a 2D or 3D graph.

    I remember to have seen some other software specialized in data visualization, interactive and able to show you more dimensions with different techniques.

    OK
    I've already found information
    http://vadl.cc.gatech.edu/documents/...h_3-MultiD.ppt

    and these programs
    Tools - WikiViz
    Now, I need to compare them

    thanks anyway
