如何在matplotlib中隐藏或显示Axes对象(子图),以便在同一图中的不同轴之间切换?
我正在使用matplotlib在Tkinter GUI中显示图形,我想使用radiobuttons在同一图中的不同轴之间切换。
基本上我会将一些radiobuttons链接到IntVar():
graphic_version = tk.IntVar()
tk.Radiobutton(root, text='Option1', variable=graphic_version, value=1).pack()
tk.Radiobutton(root, text='Option2', variable=graphic_version, value=2).pack()
然后我会使用自定义方法跟踪IntVar(),并使用所请求的图形更新我的数字:
choice.trace("w", lambda choice: myGraphic.showGraphic(version))
这样每当用户点击一个单选按钮时,该图就会使用不同版本的图更新。现在问题是我不知道如何正确地做showGraphic。假设我使用这个类系统来获得绘制相同数据的2个不同版本:
class Version1():
def __init__(self, ax, data):
self.ax = ax #This is a Axes object
self.data = self._formatDataV1(data)
self._draw()
self._setOptions()
self.hide()
def _formatDataV1(self, data):
#Here I manipulate the raw data to extract the info I need for this version
#Just a bunch of math algorithms it works fine
def _setOptions(self):
#Here I can overwrite or change settings specific for this version
def _draw(self):
self.ax.bar(self.data[0], self.data[1], width=1, color='red')
self._setOptions()
def hide(self):
###How do I remove the ax without affecting the figure?
def show(self):
###If I want to see this version again I don't want the cost of redrawing
class Version2():
def __init__(self, ax, data):
self.ax = ax #This is a Axes object
self.data = self._formatDataV1(data)
self._draw()
self._setOptions()
self.hide()
def _formatDataV2(self, data):
#The data is manipulated differently here to extract new information
def _setOptions(self):
#These options are specific to the version2 to get the display right
def _draw(self): #Drawing a different version of the graphic with differently formated data
self.ax.plot(self.data[0], self.data[1])
self._setOptions()
def hide(self):
###How do I remove the ax without affecting the figure?
def show(self):
###If I want to see this version again I don't want the cost of redrawing
class MyGraphic(tk.LabelFrame):
def __init__(self, root, data, **options):
#I use the labelframe only as a container to make things pretty
tk.LabelFrame.__init__(self, root, text="My 1337 graphic : ", **options)
self.data = data
self.fig = mpl.figure.Figure()
self.ax = self.fig.add_subplot(111)
self._drawCanvas() #This is just for Tkinter compatibility
self.my_versions = {}
self.my_versions.update({'v1' : Version1(self.ax, self.data)})
self.my_versions.update({'v2' : Version2(self.ax, self.data)})
def _drawCanvas(self):
self.canvas = FigureCanvasTkAgg(self.figure, master=self)
self.canvas.show()
self.canvas.get_tk_widget().grid()
self.canvas._tkcanvas.pack(side=tk.TOP, fill=tk.BOTH, expand=1)
def _setOptions(self, **kwargs):
#Here I can set options common to both versions of the graphic
def showGraphic(self, graphic_version):
for i, item in enumerate(self.my_versions):
item.hide()
if graphic_version == 1:
self.my_versions['v1'].show()
elif graphic_version == 2:
self.my_versions['v2'].show()
self._setOptions()
对于冗长的帖子感到抱歉,但我宁愿包含太多细节,并编辑那些在解决后不必要的人。
基本上我希望能够隐藏并在同一个数字上显示不同的斧头,具体取决于我的用户所做的选择。这个难题的缺失部分是myGraphic.show()和myGraphic.hide()。
我也是一个完整的matplotlib newby我尝试了这个设计,因为在需要时它似乎很容易实现其他版本,但设计输入也非常受欢迎。

您可以使用figure.delaxes从图中删除轴(并使用add_axes添加): http://matplotlib.org/api/figure_api.html#matplotlib.figure.Figure.delaxes

我设法通过figure.clear()
和figure.add_axes(ax)
来解决问题
