[英]Converting one large figure into several smaller figures using Pythons Matplotlib
I have an 'x' column (x_parameter) and multiple 'y' columns (filtered_data) and I'm trying to produce a scatter plot for each x,y pair. 我有一个“ x”列(x_parameter)和多个“ y”列(filtered_data),我试图为每个x,y对生成散点图。 I have done this successfully in the following function:
我已经在以下功能中成功完成了此操作:
def scatter_plot(self,filtered_data,x_parameter):
for i in range(len(filtered_data)):
if filtered_data[i].name==x_parameter:
x=filtered_data[i]
x_index=list(x.keys())
figure()
for i in range(len(filtered_data)):
y=filtered_data[i]
y_index=list(y.keys())
index_intersection = list(set(x_index)&set(y_index))
subplot(10,5,i)
scatter(x[index_intersection],y[index_intersection])
This produces one large figure with 43 sublots. 这将产生一个带有43个子批的大图形。 I am now trying to change this so that I produce 3 smaller figures with two 4x4 subplots and the remainder in the last.
我现在正在尝试更改此设置,以便生成3个较小的图形,其中包含两个4x4子图,其余的在最后一个。 I would also like this function to be dynamic and be able to handle any inputs of any size and still return figure 'units' of 16 subplots and a remainder figure.
我还希望此功能是动态的,并且能够处理任何大小的任何输入,并且仍返回16个子图的图形“单位”和其余图形。 My attempt at doing this is below:
我的尝试如下:
def scatter_plot(self,filtered_data,x_parameter):
number_of_full_subplots=len(filtered)/16
remainder=len(filtered)-(number_of_full_subplots*16)
for i in range(len(filtered_data)):
if filtered_data[i].name==x_parameter:
x=filtered_data[i]
x_index=list(x.keys())
for j in range(number_of_full_subplots+1):
figure(j)
for i in range(len(filtered_data)):
y=filtered_data[i]
y_index=list(y.keys())
index_intersection = list(set(x_index)&set(y_index))
x_to_plot=x[index_intersection]
y_to_plot=y[index_intersection]
for k in range(16):
plt.subplot(4,4,k)
plt.scatter(x_to_plot,y_to_plot)
However this produces 3 figures of the appropiate size but with the same graph in each space. 但是,这会生成3个适当大小的图形,但每个空间中的图形相同。 Could anybody spot my mistake?
有人可以发现我的错误吗?
Here is an example of the 'filtered_data' variable. 这是'filtered_data'变量的示例。 It was created by another function and is a list of pandas series.
它是由另一个函数创建的,是熊猫系列的列表。 For each x and y pair I only plot the data if the indices appear in both series.
对于每个x和y对,我仅在索引同时出现在两个系列中时才绘制数据。
