deb*_*e4u 10 python matplotlib pandas
我正在使用matplotlib.pyplot从Dataframe绘制图形。在这里,我想显示每个矩形上条形的高度,并且正在使用Text()。为了标准化Y轴,我在Y轴上采用了Logscale。以下是我的代码,出现错误
Image size of 1005x132589 pixels is too large. It must be less than 2^16 in each direction

当我不使用时,plt.yscale('log')代码工作正常。根据一些建议,我也重新启动了内核,但仍然遇到此问题。欢迎对此提出任何建议。
我的代码:
`
#收集到的数据列出。list_alarms = df_region.alarmName#list_east = df_region.EAST list_west = df_region.WEST list_north = df_region.NORTH list_south = df_region.SOUTH
# X-ticks customization
N = len(list_alarms)
xpos = np.arange(N)
# this json file is used to update the style of the plot.
s = json.load(open('style.json'))
rcParams.update(s)
# Graph customize
plt.rcParams['figure.figsize'] = (15,8)
plt.xlabel('AlarmNames at different Regions')
plt.ylabel('Frequency for alarms in MNG-PAN devices')
plt.title('Alarm Generated by MNG-PAN Device at different Regions')
plt.xticks(xpos,list_alarms, rotation = 280)
# bar1 = plt.bar(xpos - 0.3,list_east, width = 0.2, label = 'EAST',
color = '#3154C8')
bar2 = plt.bar(xpos - 0.1, list_west, label = 'WEST', color =
'#FF9633')
bar3 = plt.bar(xpos + 0.1, list_north, label = 'NORTH', color =
'#12B794')
bar4 = plt.bar(xpos + 0.3, list_south, label = 'SOUTH', color =
'#EF6FE3')
plt.yscale('log')
plt.legend()
def autolabel(rects):
for rect in rects:
height = rect.get_height()
if height < 10000:
plt.text(rect.get_x() + rect.get_width()/2., 1.05*height,
'%d'%int(height),
ha = 'center', va = 'bottom', rotation = 90,
fontsize=9)
# # autolabel(bar1)
autolabel(bar2)
autolabel(bar3)
autolabel(bar4)
plt.show()

我正在使用Jupyter Notebook,Pandas,Python3。
它使用关键字参数对我有用transform=ax.transAxes:
例如:
plt.text(0.5, 0.5, 'Some text', transform=ax.transAxes)

您可以调整像素并更新 update_datalim()
fig = plt.figure(1, figsize=(8, 14), frameon=False, dpi=100)
fig.add_axes([0, 0, 1, 1])
ax = plt.gca()
corners = ((x1, y1), (x2, y2))
ax.update_datalim(corners)
