Prevent exceptions on empty logarithmic graphs
Major and minor x-axis labels
Adds options to
- specify major labels manually
- specify major labels automatically based on an interval
- specify major labels automatically based on a count
- suppress diplay of minor labels
- give major labels a different font size
The 'x_labels_num_limit' option has been removed. This functionality can also be achieved with the new options and now works for other graph types than Line.
