Matplotlib-在单元格中创建带有线图的表格吗? [英] Matplotlib- Creating a table with line plots in cells?
问题描述
我有一些历史棒球数据,试图在一个简单的matplotlib图中可视化,在1个子图中,我想要一张表格来显示过去一年的平均统计数据,每个统计数据的折线图以及最终得分这是独立计算的.
I have historical baseball data that I'm trying to visualize in a simple matplotlib plot Within 1 subplot I want to have a table that shows average statistics over the past year, a line chart for each statistic, and then a final score which is calculated independently.
我知道matplotlib具有表格功能,因此创建5x3表格会很简单,但是可以将表格作为值插入图表吗?如果没有,我应该怎么做?我想我可以创建几个子图,但是格式化会很古怪,而且不是很动态.感谢帮助.
I know matplotlib has a table function so it would be simple to create a 5x3 table, but is it possible to insert plots as a value in a table? If not, are there any suggestions on what I should do? I guess I could create several subplots, but formatting would be wacky and not very dynamic. Appreciate the help.
使用@TheImportanceofBeingErnest的代码,我遇到了matplotlib的错误,在使用gridspec时我看不到x轴:
Using @TheImportanceofBeingErnest's code, I'm encountering a bug with matplotlib where I can't see the x axis when I use gridspec:
fig = plt.figure(figsize=(8.5,11))
gs_row1left = gridspec.GridSpec(1,1)
gs_row1right = gridspec.GridSpec(1,1)
summaryplot2subplot(fig, gs_row1left[0], data, col1, col2, finalsc)
ax.axis('off')
ax2 = fig.add_subplot(gs_row1right[0, 0])
df = pd.DataFrame({'year':['2001-01','2002-01','2003-01','2004-01','2005-01'], 'value':[100,200,300,400,500]})
barax = ax2.twinx()
df['value1']= df['value']*0.4
df['value2'] = df['value']*0.6# Let them be strings!
df.plot(x = ['year'], y = ['value'], kind = 'line', ax = ax2)
df.plot(x = ['year'], y= ['value1','value2'], kind = 'bar', ax = barax)
gs_row1left.update(left = 0.05, right = 0.48)
gs_row1right.update(left = 0.55, right = 0.98)
plt.show()
推荐答案
无法将图插入到matplotlib表中.但是,子图网格允许创建类似表格的行为.
It is not possible to insert plots into a matplotlib table. However subplot grids allow to create a table-like behaviour.
import matplotlib.pyplot as plt
import numpy as np
data = np.random.rand(100,4)
col1 = ["WAR", "ERA", "IP", "WHIP", "Final\nScore"]
col2 = [0.23,1.60,0.28,0.02,0.38]
col2colors = ["red", "g", "r", "r", "r"]
finalsc = "D+"
fig, axes = plt.subplots(ncols=3, nrows=5, figsize=(4,2.6),
gridspec_kw={"width_ratios":[1,0.5,2]})
fig.subplots_adjust(0.05,0.05,0.95,0.95, wspace=0.05, hspace=0)
for ax in axes.flatten():
ax.tick_params(labelbottom=0, labelleft=0, bottom=0, top=0, left=0, right=0)
ax.ticklabel_format(useOffset=False, style="plain")
for _,s in ax.spines.items():
s.set_visible(False)
border = fig.add_subplot(111)
border.tick_params(labelbottom=0, labelleft=0, bottom=0, top=0, left=0, right=0)
border.set_facecolor("None")
text_kw = dict(ha="center", va="bottom", size=13)
for i,ax in enumerate(axes[:,0]):
ax.text(0.5, 0.05, col1[i], transform=ax.transAxes, **text_kw)
for i,ax in enumerate(axes[:,1]):
ax.text(0.5, 0.05, "{:.2f}".format(col2[i]),transform=ax.transAxes, **text_kw)
ax.set_facecolor(col2colors[i])
ax.patch.set_color(col2colors[i])
axes[-1,-1].text(0.5, 0.05, finalsc,transform=axes[-1,-1].transAxes, **text_kw)
for i,ax in enumerate(axes[:-1,2]):
ax.plot(data[:,i], color="green", linewidth=1)
plt.show()
要将多个这样的图放入一个图形中,您将采取一些不同的方法,并创建带有多个子网格的gridspec.
To put several such plots into a figure you would approach this a bit differently and create a gridspec with several subgrids.
import matplotlib.pyplot as plt
from matplotlib import gridspec
import numpy as np
def summaryplot2subplot(fig, gs, data, col1, col2, finalsc):
col2colors = ["g" if col2[i] > 1 else "r" for i in range(len(col2)) ]
sgs = gridspec.GridSpecFromSubplotSpec(5,3, subplot_spec=gs, wspace=0.05, hspace=0,
width_ratios=[0.9,0.7,2])
axes = []
for n in range(5):
for m in range(3):
axes.append(fig.add_subplot(sgs[n,m]))
axes = np.array(axes).reshape(5,3)
for ax in axes.flatten():
ax.tick_params(labelbottom=0, labelleft=0, bottom=0, top=0, left=0, right=0)
ax.ticklabel_format(useOffset=False, style="plain")
for _,s in ax.spines.items():
s.set_visible(False)
border = fig.add_subplot(gs)
border.tick_params(labelbottom=0, labelleft=0, bottom=0, top=0, left=0, right=0)
border.set_facecolor("None")
text_kw = dict(ha="center", va="bottom", size=11)
for i,ax in enumerate(axes[:,0]):
ax.text(0.5, 0.05, col1[i], transform=ax.transAxes, **text_kw)
for i,ax in enumerate(axes[:,1]):
ax.text(0.5, 0.05, "{:.2f}".format(col2[i]),transform=ax.transAxes, **text_kw)
ax.set_facecolor(col2colors[i])
ax.patch.set_color(col2colors[i])
axes[-1,-1].text(0.5, 0.05, finalsc,transform=axes[-1,-1].transAxes, **text_kw)
for i,ax in enumerate(axes[:-1,2]):
ax.plot(data[:,i], color=col2colors[i], linewidth=1)
fig = plt.figure(figsize=(8,6))
gs = gridspec.GridSpec(2,2)
col1 = ["WAR", "ERA", "IP", "WHIP", "Final\nScore"]
finalsc = "D+"
for i in range(4):
data = np.random.rand(100,4)
col2 = np.random.rand(5)*2
summaryplot2subplot(fig, gs[i], data, col1, col2, finalsc)
plt.show()
