# xgx_breaks_time

##### Sets the default breaks for a time axis

`xgx_breaks_time`

sets the default breaks for a time axis,
given the units of the data and the units of the plot.
It is inspired by scales::extended_breaks

##### Usage

`xgx_breaks_time(data_range, units_plot)`

##### Arguments

- data_range
range of the data

- units_plot
units to use in the plot

##### Details

for the extended breaks function, Q is a set of nice increments w is a set of 4 weights for

simplicity - how early in the Q order are you

coverage - labelings that don't extend outside the data: range(data) / range(labels)

density (previously granularity) - how close to the number of ticks do you get (default is 5)

legibility - has to do with fontsize and formatting to prevent label overlap

##### Value

numeric vector of breaks
