Hi Rich, Being in a position of relative ignorance on this topic, I'll offer some suggestions that may well be useless.
You mention ternary diagrams, which use position to represent compositional proportions. These will not scale up to 46 values in any way that I can imagine. If you want to display relative concentration or the like, differentiate the components and display numeric information about each component, you may be looking for a variant of the Hinton diagram. This is a bit like a heatmap where the squares are of different sizes, representing relative numeric values. In the Hinton diagram, the colors represent sign (+-), but you would probably want more complex coloring. Finally, identifying labels and/or values could be displayed on each cell of the matrix. It would not be too difficult to program something like this, so if this idea is not completely useless, let me know. It is of course possible to go the interactive route and produce a "play with me" display if necessary.
