What happened to minor breaks in 2023

[ygk2zhang]

Hi,

I would like to know how to enable minor_breaks. I use Plotnine on GoogleColabs
Last year I could run:

from plotnine import *
import plotnine as plotnine
plotnine.options.figure_size=(7, 7)

(ggplot(pmf,aes(x='x_coord'))

• geom_line(aes( y='predicted', color ='"blue"', linetype='"solid"'), size=1.5)+theme_classic(base_size=22)
• geom_line(aes( y='y_coord', color ='"blue"', linetype='"dashdot"'), size=1)
• geom_point(aes( y='predicted', color='"red"', shape='"o"'), size=0)+theme(legend_position=(0.77,0.85))
• geom_point(aes( y='y_coord', color='"red"', shape='""'), size=3)+labs(x='Distance, Å', y='PMF, kcal/mol')+scale_x_continuous(minor_breaks=2)
• scale_colour_manual(name=" ", labels=( 'Mesoscale', 'Atomistic'), values = ( "black","red"))
  +scale_linetype_manual(name=" ", labels=( 'Mesoscale', 'Atomistic'), values =( 'solid',''))
• scale_shape_manual(name=" ", labels=('Mesoscale', 'Atomistic'), values = ("","o"))
• theme(axis_title_y=element_text(margin={'t': 0, 'b': 0, 'l': 0, 'r':-3}), axis_ticks_direction='in',axis_title_x=element_text(margin={'t':-2, 'b': 0, 'l': 0, 'r':0}) ))

Now if I rerun the same job on GoogleColabs with plotnine 0.10.0 , I don't get the minor breaks I have plotnine 0.8 on my laptop and still do not get the minor breaks

The question is how to do I get get the minor breaks back?

You can turn on the minor breaks with

+ theme(axis_ticks=element_line())         # turn on major & minor breaks
+ theme(axis_ticks_minor=element_line())   # turn on minor breaks
+ theme(axis_ticks_minor_x=element_line()) # turn on minor breaks for the x axis
+ theme(axis_ticks_minor_y=element_line()) # turn on minor breaks for the y axis
