보통 Data Science상에서 주로 쓰는 Python Visualization package가 여러 개 있는데, 많이 쓰는 것이 Scipy package에 들어있는 matplotlib.pyplot (보통 plt라고 alias해서 사용한다.) 거기서 주로 사용하는 기능에 대해서 간단히 다뤄보고자 한다. 우선 첫번째로 다룰 기능 multiple plot이다. 보통 그래프를 그리게 되면 한 plot당 하나의 그래프가 출력되겠지만, 필요에 따라서는 여러 개의 plot. Creating multiple subplots using. plt.subplots. ¶. pyplot.subplots creates a figure and a grid of subplots with a single call, while providing reasonable control over how the individual plots are created Multiple Plots using subplot () Function A subplot () function is a wrapper function which allows the programmer to plot more than one graph in a single figure by just calling it once. Syntax: matplotlib.pyplot.subplots (nrows=1, ncols=1, sharex=False, sharey=False, squeeze=True, subplot_kw=None, gridspec_kw=None, **fig_kw data.plot (x = 'x' , y = 'y' , figsize = ( 10, 5 )) 이를 group에 따라 다른 색상 으로 그려주는 방법은 다음과 같다. 처음에 size 등 그래프의 기본적인 parameter들을 설정해준다. group별로 지정해주고 싶은 색을 정의해주고, for 문으로 group별로 scatter plot을 그려준다. fig,ax = plt.subplots (figsize= ( 10, 5 )) # size colors = [ '#F8766D', gray] # group별 color 지정 for i, (name,group) in enumerate (data.groupby. You can keep adding plt.plot as many times as you like. As for line type, you need to first specify the color. So for blue, it's b. And for a normal line it's -. An example would be: plt.plot(total_lengths, sort_times_heap, 'b-', label=Heap
Python plot multiple lines from dataframe You can plot multiple lines from the data provided by a Dataframe in python using matplotlib. You can do it by specifying different columns of the dataframe as the x and y-axis parameters in the matplotlib.pyplot.plot () function. You can select columns by slicing the dataframe Matplotlib.pyplot provides a feature of multiple plotting. The inbuilt function matplotlib.pyplot.plot () allows us to do the same.
