Intro to Matplotlib xlim Matplotlib is a powerful plotting library for Python that provides a wide variety of customizable options to create visually appealing plots. The current x-axis limits in data coordinates. This can get tricky as you and the state machine's might disagree on which Axes is The Current Axes. Some plots only contain values from 0 to 1 and some contain values in the millions. plt has many fewer options than working directly with the axes object. close() ちなみにmplは6. It's a shortcut string notation described in the Notes section below. set_xlim([0, None]) # this is the shortest solution # upper limit is 10, lower is "auto" # this is all equivalent 출력: 출력 그림에서 볼 수 있듯이, 우리가xlim()및ylim()함수를 사용하지 않으면, 우리는0에서10 사이의 X 축 범위의 모든 범위의 축으로 플롯을 얻을 것입니다 -축 범위는0에서2 사이입니다. xlim() One of the simplest ways to change the x-axis range of a histogram is by using the plt. xlim() 2. These functions allow you to specify the minimum and maximum values for each axis. Remember that good axis limits can make the difference between a clear, informative visualization and a Setting limits turns autoscaling off for the x-axis. All arguments are passed though. set_zlabel('Z') ax. set_xlim( ( min_val, max_val ) ) # improve formatting fig. ylim() The simplest way to set X and Y limits in Matplotlib is by using the plt. ax. set_xlim([x[0], x[-1]]) The whitespace margin left and right of your axis will disappear then, though.
