Pylab 直方图显示 x 轴上的所有 bin
我正在编写一个小型 python 程序来进行频率分析，我想知道如何让所有 bin 显示在 x 轴上，而不是仅以 5 为增量显示。还有一种方法可以显示像“这样的字符串值” x 轴上的 A" 而不是数字？
代码：
print "Please specify the file to analyse."
FileContents = FileToIntArray()
# Count letter occurances in file
letterCounts = zeros(26).tolist()
for x in FileContents:
i = AlphaNum.index(x)
letterCounts[i] = letterCounts[i] + 1
# Plot histogram of counts
print "" # Newline
title("Absolute Frequencies")
xlabel("Letters A-B (Where A = 0 & Z = 25)")
ylabel("Letter Occurences")
hist(letterCounts, bins=AlphaNum)
show()
谢谢， 亚历克斯.
Im writing a small python program to do a frequency analysis, and I was wondering how you might get all the bins to show on the x axis rather then just in increments of 5. Also is there a way you can display a string value like "A" on the x axis instead of a number?
Code:
print "Please specify the file to analyse."
FileContents = FileToIntArray()
# Count letter occurances in file
letterCounts = zeros(26).tolist()
for x in FileContents:
i = AlphaNum.index(x)
letterCounts[i] = letterCounts[i] + 1
# Plot histogram of counts
print "" # Newline
title("Absolute Frequencies")
xlabel("Letters A-B (Where A = 0 & Z = 25)")
ylabel("Letter Occurences")
hist(letterCounts, bins=AlphaNum)
show()
Thanks,
Alex.
