    <p>I'm using Python in an attempt to analyse a large chunk of empiric measurements. In essence, I've two functions transforming the empiric data which also takes 3 'count' parameters - and returns a sequence of floats in each configuration. I'm expecting (hoping) to see some interesting patterns emerge when appropriate parameters are selected. I anticipate that the patterns might be relative between sequences returned for each function - and/or relate to patterns of some kind in the parameters. In case it's relevant, the 3 'count' parameters roughly correspond to:</p> <ul> <li>A 'window size' on the underlying data over which summary statistics are calculated</li> <li>A number of consecutive windows used to compute a single summary statistic (i.e. the trade-off between greater spatial or greater temporal accuracy)</li> <li>An 'minimum age' - an offset into history of the underlying data.</li> </ul> <p>The summary statistics (which generate the resulting sequences of floats for each parameter configuration) are non-trivial but will be independently sensitive to all three parameters.</p> <p>I'm interested in visualisation techniques - suited to RAD/ad-hoc enquiry that will help me experiment with this multi-dimensional data.</p> <p>So far, I've tinkered with <a href="http://matplotlib.sourceforge.net/" rel="noreferrer">MatPlotLib</a> but find being restricted generating two graphs of 2/3 dimensions in the style of batch processing makes investigation very tedious. Ideally, I'd find a tool that would allow me to visualise more than two dimensions... perhaps allowing me to switch real-time between dimensions in an interactive GUI.</p> <p>I'd really appreciate hints from any visualisation gurus as to suitable tools I should investigate - ideally to integrate with my existing Python functions - or in other languages. I'd especially like to hear any anecdotes of success with similar visualisation problems.</p> <p><strong><em>EDIT to add</em></strong>: One possible approach I'm considering is to use animation on 2 or 3D plots (to capture another dimension... leaving 1 or 2 for manual selection)... though I've found no good tools to help me achieve this, yet.</p>

    1. COMatplotlib is great and does support [3D plots](http://matplotlib.sourceforge.net/mpl_toolkits/mplot3d/index.html).

    3. COThe orange.biolab.si stuff looks neat - but I can't see any way to use it to visualise this sort of multi-dimensional data.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
