Bug: NMR block throws errors

[MJCliffe]

When uploading NMR data to a block it seems to throw a few errors and it doesn't plot, although the metadata are accurately read.

NMRBlock raised error: unexpected attribute 'x_range' to Button, possible attributes are align, aspect_ratio, background, button_type, css_classes, default_size, disabled, height, height_policy, icon, js_event_callbacks, js_property_callbacks, label, margin, max_height, max_width, min_height, min_width, name, sizing_mode, subscribed_events, syncable, tags, visible, width or width_policy

Plotting currently not available for data with dimension > 1

This is a 1D zg so should be a simple case I think.
