我刚刚开始在Python中进行可视化实验。通过下面的代码,我尝试将排序功能添加到从数据帧绘制的Matplotlib条形图中。我想在图上添加一个button
,如sort
,这样当它被点击时,它将以从最高销售数字到最低销售数字的顺序显示一个新的绘图,目前可以显示该按钮,但无法触发排序功能。任何想法或建议都将不胜感激
[更新的尝试]
import matplotlib.pyplot as plt
from matplotlib.widgets import Button
def sort(data_frame):
sorted = data_frame.sort_values('Sales')
return data_frame2
def original():
return data_frame
data_frame.plot.bar(x="Product", y="Sales", rot=70, title="Sales Report");
plot.xlabel('Product')
plot.ylabel('Sales')
axcut = plt.axes([0.9, 0.0, 0.1, 0.075])
bsort = Button(axcut,'Sort')
bsort.on_clicked(sort)
axcut2 = plt.axes([1.0, 0.0, 0.1, 0.075])
binit = Button(axcut2,'Original')
binit.on_clicked(original)
plt.show()
预期图形输出
整合
import matplotlib.pyplot as plt
from matplotlib.widgets import Button
import seaborn as sns
%matplotlib notebook
class Index(object):
ind = 0
global funcs
def next(self, event):
self.ind += 1
i = self.ind %(len(funcs))
x,y,name = funcs[i]() # unpack tuple data
for r1, r2 in zip(l,y):
r1.set_height(r2)
ax.set_xticklabels(x)
ax.title.set_text(name) # set title of graph
plt.draw()
class Show():
def trigger(self):
number_button = tk.Button(button_frame2, text='Trigger', command= self.sort)
def sort(self,df_frame):
fig, ax = plt.subplots()
plt.subplots_adjust(bottom=0.2)
######intial dataframe
df_frame
######sorted dataframe
dfsorted = df_frame.sort_values('Sales')
x, y = df_frame['Product'], df_frame['Sales']
x1, y1 = df_frame['Product'], df_frame['Sales']
x2, y2 = dfsorted['Product'], dfsorted['Sales']
l = plt.bar(x,y)
plt.title('Sorted - Class')
l2 = plt.bar(x2,y1)
l2.remove()
def plot1():
x = x1
y = y1
name = 'ORginal'
return (x,y,name)
def plot2():
x = x2
y = y2
name = 'Sorteds'
return (x,y,name)
funcs = [plot1, plot2]
callback = Index()
button = plt.axes([0.81, 0.05, 0.1, 0.075])
bnext = Button(button, 'Sort', color='green')
bnext.on_clicked(callback.next)
plt.show()
我已经使用著名的}和
titanic
数据集对class
和# of survivors
进行了基本比较,包括了两个可重复的示例,用于在下面的x轴上对matplotlib
{plot
(即直线)进行交互式排序:对于
bar
图,您必须使用set_height
循环通过矩形,例如for r1, r2 in zip(l,y): r1.set_height(r2)
;对于line
图,您使用set_ydata
,例如l.set_ydata(y)
如果使用jupyter笔记本,请确保使用
%matplotlib notebook
