_update_patch_transform(): AttributeError: 'Rectangle' object has no attribute '_y'

[mmokrejs]

Hi,
I have another case where matplotlib-1.2.1 crashes somewhere deeply.

...
draw_hist_plot('somefile.png', _mydata, _colors, _title, _xlabel, _ylabel, _legends, legend_loc=_legend_loc, legend_bbox_to_anchor=_legend_bbox_to_anchor, ymin=0, fontsize=10, dpi=100, bin_count=_bin_count)

Do you have a simple, self-contained example that reproduces the bug?

[mmokrejs]

Unfortunately not, I hope you can handcraft something as you know what is the code doing. If not, please let me know and I will try to find some time, but am not very optimistic.

[mdboom]

The problem is, I don't know what your code is doing to cause this, so I would have to go hunting to reproduce this error (which our test suite obviously doesn't find).

http://sscce.org/ may explain better what I'm getting at.

@mmokrejs, it is hard to see how this error could occur in normal use. The _x and _y attributes of the Rectangle are created upon initialization. The traceback indicates that the _x attribute is still there, but the _y attribute has somehow disappeared.

If you can run inside of ipython, you could use %debug for post-mortem debugging to find out where your Rectangle object came from, and whether it is missing any other attributes.

I have this question:AttributeError: 'Rectangle' object has no property 'normed'
The code is :
import random
import matplotlib.pyplot as plt

#解决中文显示问题
plt.rcParams['font.sans-serif'] = ['SimHei']
plt.rcParams['axes.unicode_minus'] = False

def roll_dice():
"""
模拟掷骰子

"""
roll = random.randint(1,6)
return roll

def main():
total_times = 10

#记录骰子的结果
roll_list = []

for i in range(total_times):
    roll1 = roll_dice()
    roll2 = roll_dice()

    roll_list.append(roll1 + roll2)

#数据可视化
plt.hist(roll_list,bins = range(2,14,1),normed = 1,edgecolor = 'green',linewidth = 1)
plt.title('骰子点数统计')
plt.xlabel('点数')
plt.ylabel('频率')
plt.show()

if name=='main':
main()

so, what measures should i do to solve this problem???

[efiring]

The "normed" kwarg has been removed recently for consistency with np.histogram. Use density=True instead.
In the future, please ask questions like this on the matplotlib-users mailing list or stackoverflow, and use an SSCCE (http://sscce.org/) to illustrate--strip it down to the bare minimum. Also specify the matplotlib version.

Thank you very much

my matplotlib version 2.1.0
I have a case :
AttributeError: 'Rectangle' object has no property 'normed'

The cord is:

import random
import matplotlib.pyplot as plt
plt.rcParams['font.sans-serif'] = ['SimHei']
plt.rcParams['axes.unicode_minus'] = False
def roll_dice():
    roll = random.randint(1,6)
    return roll
def main():
    total_times = 10
    roll_list = []
    for i in range(total_times):
        roll1 = roll_dice()
        roll2 = roll_dice()
        roll_list.append(roll1 + roll2)
    plt.hist(roll_list,bins = range(2,14,1),normed = 1,edgecolor = 'green',linewidth = 1)
    plt.title('骰子点数统计')
    plt.xlabel('点数')
    plt.ylabel('频率')
    plt.show()

if __name__=='__main__':
    main()

@joker-wutong there's no normed keyword argument to plt.hist. It was deprecated a while back, and now the density flag is a close analogue.
