gdesk.utils.ticks module

class gdesk.utils.ticks.Ticks(minVal, maxVal, scale, minimumSpacing=None, noDecimals=False)

Bases: object

update(minVal, maxVal, scale)

gdesk.utils.ticks.getOptimalMinimumSpacing(minVal, maxVal, scale=1)

gdesk.utils.ticks.tickSpacing(minimumSpacing=1, noDecimals=False)

Return values describing the desired spacing and offset of ticks.

This method is called whenever the axis needs to be redrawn and is a good method to override in subclasses that require control over tick locations.

The return value must be a list of three tuples:

[
    (major tick spacing, offset),
    (minor tick spacing, offset),
    (micro tick spacing, offset),
    ...
]

gdesk.utils.ticks.tickValues(minVal, maxVal, scale, minimumSpacing=None, noDecimals=False)

Return the values and spacing of ticks to draw:

[  
    (spacing, [major ticks]), 
    (spacing, [minor ticks]), 
    ... 
]

By default, this method calls tickSpacing to determine the correct tick locations. This is a good method to override in subclasses.
