Hi, First of all, I'd like to thank Bill et al. for having written such a powerful Library. Here are my two questions: 1>I'm using an Irregular3DSet to define the domain_set of a FlatField. I need double precision for my datasets. Why can't we use double with an Irregular3DSet ? Is there any other way to create a 3D domain_set based on non gridded double values (w/o using Irregular3DSet) ? I would like to avoid rescaling and recasting to float the datasets to get the right information on the scale axis. 2> Is there any way to make an axis display [-1000;1000] for let's say data that have previously been rescaled to [-1.0;1.0] ? Thank you so much for any help, Alex.
