' This sample will demonstrate how axes can automatically generate ticks at each element's position and
' how to control each element's tick independently.
' The first and second chart show 2 different ways of doing this while the third shows how to control
' an individual tick and use tokens.
' Notice that some ticks don't appear. This is because there is no space for the label, however, the
' grid line is there to indicate that a tick should be there.

' First we setup the scale.

' 3. CONTROLING INDIVIDUAL TICKS:
' Setup the scale.

' a chart with database data see the following resources:
