- Now supports plotting of RGB(A) image plots, with the new 'implot' method.
- Moved plot methods into NXdata class. This will allow plotting in NXmonitor and NXlog classes as well. If you attempt to plot another class, it will search for a valid NXdata group within its hierarchy.
- Individual NXfields also have a plot method. They will be plotted against default axes.
- Allow the plotting axes to be defined by an attribute array, as well as a single delimited string.
- Removed the NeXus version number from the file attributes when creating a new file. This version number used to refer to the C-API version, but that is no longer used.
