I think we would need to extend ParaView with an annotation filter that would show in text format values from the data set it inputs and with an easy way to assign arbitrary attribute values into a data set.
This is exactly what I need. Essentially, some sort of selection representation and arbitrary key/value pairs. The values would need to be stored somewhere. Any ideas where/how to store them? Perhaps a database?
The first would require some sort of warning, or memory limit, because it would quickly overwhelm both cpu time and screen space when applied to any data set with more than a few MB of data values. This is the reasoning behind the current annotation limitations.
Is it overwhelming because of the time it takes to render text?
The second can be done via the python filter (or for floating point numbers the calculator filter) now. However a GUI, perhaps through the spreadsheet view, would be much more user friendly. For large data sets, there will have to be some way of not having to specify every value.
Some sort of table view would be great. Each row would contain the attributes about whatever data was previously selected.
How can this be done with a python filter now?
Please submit a feature request via the bug tracker. I think this would be a really useful addition.
Cool, it's now in as case 8700.
