xgx_breaks_log10: Sets the default breaks for log10

Description

xgx_breaks_log10 sets nice breaks for log10 scale. it's better than the default function because it ensures there is at least 2 breaks and also, it will try to go by 3s (i.e. 1,3,10,30,100) if it makes sense

Usage

xgx_breaks_log10(data_range)

Arguments

data_range

range of the data

Value

numeric vector of breaks

Details

for the extended breaks function, weights is a set of 4 weights for

1. simplicity - how early in the Q order are you

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

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

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