Bug report

Bug summary

I have more than 10 majorTicks on the X-axis. label1On is False for each of the odd numbered majorTicks. Call tick_params as shown in subject and label1On is True for all MajorTick members after return.

Code for reproduction

major_ticks = axis.xaxis.get_major_ticks()
    if len(major_ticks) > 10:
        for i, tick in enumerate(major_ticks):
            if (i % 2) == 1:
                tick.label1On = False
logger.info("the value  of label1O is %r", axis.xaxis.majorTicks[1].label1On)
axis.tick_params(axis='both', which='major', length=5)
logger.info("the value  of label1O is %r", axis.xaxis.majorTicks[1].label1On)

Actual outcome

2019-01-18 16:42:28,509 - unavco.plotter.posfile - INFO - the value  of label1O is False
2019-01-18 16:42:36,626 - unavco.plotter.posfile - INFO - the value  of label1O is True

Expected outcome

I expected the value of label1On to not change.

Can you please provide a full minimal example?

label1On is deprecated since #10088; however, the equivalent code using set_visible and get_visible works without suffering from the same issue, as of master.

from pylab import *
ax = gca()
major_ticks = ax.xaxis.get_major_ticks()
for i, tick in enumerate(major_ticks):
    if i % 2 == 1:
        tick.set_visible(False)
print(ax.xaxis.majorTicks[1].get_visible())
ax.tick_params(axis='both', which='major', length=5)
print(ax.xaxis.majorTicks[1].get_visible())
plt.show()

I am going to close this as fixed in master (per the above -- the mechanism is different now), and milestone as 3.0.x in case someone really wants to put in a separate fix for that branch.
