增加yticks pandas log plot的频率？

Question

我有一个大熊猫情节，我想增加y轴上的刻度频率。这就是我在做的事情：

import pandas as pd
import seaborn as sns
import matplotlib.pyplot as plt
from matplotlib import rcParams
import numpy as np
import random
from __future__ import division
import matplotlib.ticker as ticker

df = pd.read_csv('exp-mediciones-grales-data.csv', sep=', ', engine='python')

iteraciones = str(df.loc[0]["iteraciones_totales"]) + " iteraciones"

# filtro datos
filtro = []
tams = {128, 512, 1024, 2048}
for i in range(0, len(df)):
    filtro.append(df.loc[i]["implementation"] not in {'asm-lu'} and df.loc[i]["width"] in tams)
df = df[filtro]
# print df

rcParams['figure.figsize'] = 12.0,6.0 # seteo tamaño en inches (default: 8.0, 6.0)
ax = sns.barplot(x="width", y="cycles", hue="implementation", data=df)
ax.set_xlabel("Width (#pxs)".decode('utf-8'))
ax.set_ylabel("Cant. ciclos")
ax.set_title(("Comparación ciclos totales - lena.bmp - escala log. - " + iteraciones).decode('utf-8'))
ax.set_yscale('log')
ax.yaxis.get_major_locator().set_params(numticks=10)
print(ax.yaxis.get_major_locator())
print(ax.yaxis.get_minor_locator())
print(ax.yaxis.get_major_formatter())
print(ax.yaxis.get_minor_formatter())
ax.grid();
plt.legend(loc='best')

plt.savefig('img/comp-ciclos-gral.png')
plt.show()

正在阅读以下csv文件（请注意，由于其大小，这只是真正csv的一个片段）：

输出结果为：

正如你所看到的，我尝试将滴答数设置为主要定位器，但它没有按我想要的那样做。我只想增加标签值的频率。更确切地说，我想要显示比10的幂更多的值。任何想法我怎么能实现这一点？

Answer 1

默认情况下，对数刻度轴仅在基数的整数幂（即主刻度）上标记刻度。为了显示不是基数整数幂的刻度标记（可能是次要刻度），您需要使用其中一个matplotlib.ticker.LogFormatter将minor_thresholds设置为documented：

  

在某些情况下，例如colorbar，主要和次要蜱之间没有区别;可以手动设置刻度线位置，也可以通过将刻度线置于基线的整数幂和中间位置的定位器来设置。对于这种情况，请使用minor_thresholds =（np.inf，np.inf）禁用minor_thresholds逻辑，以便标记所有刻度。

您可能还想设置次要刻度，以使其标签不会重叠。这是我的例子：

import matplotlib.ticker as ticker
import numpy as np
import pandas as pd
import seaborn as sns

df = pd.DataFrame({'width': ['a', 'b', 'c', 'a', 'b', 'c'],
                   'cycles': [2e5, 3e6, 4e7, 7e5, 8e6, 9e7],
                   'implementation': ['A', 'A', 'A', 'B', 'B', 'B']})
ax = sns.barplot(x="width", y="cycles", hue="implementation", data=df)
ax.set_yscale('log')
ax.yaxis.set_minor_locator(ticker.LogLocator(subs=[2,3,5,7]))
ax.yaxis.set_minor_formatter(ticker.LogFormatterSciNotation(minor_thresholds=(np.inf, np.inf)))
