所以在我的一生中,我不知道如何让标签显示小数点,而不仅仅是0,1,2
我需要它们是十进制的,下面是我用python3编写的代码
#ROE and Growth
Tax_Burden = stock.loc['Net Income']/stock.loc['Pre-Tax Income']
Interest_Burden= stock.loc['Pre-Tax Income']/stock.loc['Operating Income']
Operating_Margin= stock.loc['Operating Income']/stock.loc['Revenue']
Asset_Turnover= stock.loc['Revenue']/stock.loc['Total Assets Average']
Leverage_Ratio= stock.loc['Total Assets Average']/stock.loc['Total Equity Average']
roe=Tax_Burden*Interest_Burden*Operating_Margin*Asset_Turnover*Leverage_Ratio
Growth = roe * (1-stock.loc['Dividend Payout Ratio'])
astart = 21
aend = 31
annual = [Operating_Margin[astart:aend],Tax_Burden[astart:aend],Interest_Burden[astart:aend],Asset_Turnover[astart:aend],Leverage_Ratio[astart:aend],roe[astart:aend],Growth[astart:aend]]
N = len(annual[0])
ind = np.arange(N) # the x locations for the groups
width = .12 # the width of the bars
fig, ax = plt.subplots(figsize=(20,10))
rects1 = ax.bar(ind, annual[0], width, color='y')
rects2 = ax.bar(ind+width, annual[1], width, color='r')
rects3 = ax.bar(ind+width*2, annual[2], width, color='b')
rects4 = ax.bar(ind+width*3, annual[3], width, color='k')
rects5 = ax.bar(ind+width*4, annual[4], width, color='c')
rects6 = ax.bar(ind+width*5, annual[5], width, color='k')
rects7 = ax.bar(ind+width*6, annual[6], width, color='r')
# add some text for labels, title and axes ticks
ax.set_ylabel('Percentage')
ax.set_title('ROE Annual')
ax.set_xticks(ind + width / 2)
ax.set_xticklabels(list(stock.loc['Fiscal Period'][astart:aend]))
#ax.legend((rects1[0], rects2[0]), ('workinprogress'))
def autolabel(rects, ax):
# Get y-axis height to calculate label position from.
(y_bottom, y_top) = ax.get_ylim()
y_height = y_top - y_bottom
for rect in rects:
height = rect.get_height()
# Fraction of axis height taken up by this rectangle
p_height = (height / y_height)
# If we can fit the label above the column, do that;
# otherwise, put it inside the column.
if p_height > 0.95: # arbitrary; 95% looked good to me.
label_position = height - (y_height * 0.05)
else:
label_position = height + (y_height * 0.01)
ax.text(rect.get_x() + rect.get_width()/2, label_position,
'%d' % int(height),
ha='center', va='bottom')
autolabel(rects1,ax)
autolabel(rects2,ax)
autolabel(rects3,ax)
autolabel(rects4,ax)
autolabel(rects5,ax)
autolabel(rects6,ax)
autolabel(rects7,ax)
plt.show()
我知道到目前为止它并不漂亮,不懒惰需要做更多的功能,但似乎无法克服这个问题。谢谢你的关注。在
编辑:对于那些寻找未来的人来说,问题是这里的S运算符matplotlib documentation。杰伊帮助澄清了下面的问题。我附上了我的代码和新的图表,以便复制方便。仍然需要一些调整,但这是个人喜好。在
^{pr2}$
我认为问题出在下面的陈述上。使用
float
代替int
Jay的解决方案对我不起作用,但这确实:
