How to update depreciated tick1On and tick2On in matplotlib?

    # Turn off all the ticks
    for t in ax.xaxis.get_major_ticks():
        t.tick1On = False
        t.tick2On = False
    for t in ax.yaxis.get_major_ticks():
        t.tick1On = False
        t.tick2On = False

Updating the code as per warnings throwing an error

    # Turn off all the ticks
    for t in ax.xaxis.get_major_ticks():
        t.Tick.tick1line.set_visible = False
        t.Tick.tick2line.set_visible = False
    for t in ax.yaxis.get_major_ticks():
        t.Tick.tick1line.set_visible = False
        t.Tick.tick2line.set_visible = False

AttributeError: 'XTick' object has no attribute 'Tick'

I'm able to hide these depreciation warnings using

import warnings
warnings.filterwarnings("ignore", category=UserWarning)

But I want to update it with latest compatibility. The complete code can be found here confusion_matrix_pretty_print.py

CodePudding user response：

I think the error message meant for you to substitute like so:

for t in ax.xaxis.get_major_ticks():
    t.tick1line.set_visible(False)
    t.tick2line.set_visible(False)
