Demo Calculate Manual Ticks

Demonstrate manual ticks specification. One can specify tick locations with strings like:

• +20 every 20 units, whatever the data units are.
• +20s every 20 seconds
• 0,20,40,60,100 explicit locations.
• +20s/4 every 20 seconds, with four minor divisions.
• +20s/5,10,15 minor ticks repeat each 20s.
• 100,200,300/50,150,250,350 explicit list of major and minor ticks.
• *10/+1 log ticks with linear minor ticks.
