调研方向

在报告的 Chrome 环境中,于 ipympl notebook 集成中复现所提供的 Python 单元格,包括首次运行、引发的异常、图形大小调整以及浏览器缩放级别。比较初始渲染与后续运行;当图形以正确大小渲染,并且异常发生后缩放矩形仍保持对齐而无需调整大小或重新运行时,即表示完成。

描述

Reposting from jupyter/notebook issue. The code cell as appears in the screen shot is:

import ipympl
import matplotlib.pyplot as plt

def plot_something():
    plt.figure()
    plt.plot([0,2],[0,2],'-')
    plt.show()

plot_something()
raise Exception

The behavior I am seeing is different for the first time I run the cell and the next times. It is also different for different level of browser zoom levels (I am using Chrome 56.0.2924.87 on Windows 8.1)-

First time that the cell is run -
The figure appears but is not fully rendered (see image)-
notebook_matplotlib_exception_ipympl
If I then resize the figure using the GUI (bottom right corner), the behavior changes based on browser zoom level-

  1. When using 100% zoom level (default), the figure is rendered too small. When in this state the zoom rectangle is drawn offset from the mouse pointer. The zooming is determined by the mouse pointer, it is just the drawing of the rectangle that is off.
  2. When using 90% zoom level (ctrl^- once), the figure is rendered to size and the zoom rectangle is working fine.

When I rerun the cell the figure is re-rendered properly without need for resizing and independent of zoom level.
