如何在matplotlib中更改y轴值 参考:how to change y axis values in matplotlib Matplotlib是一个Python库,用于绘制数据可视化图表。在使用Matplotlib绘制图表时,我们经常需要调整图表中的y轴值,以便更好地展示数据。本文将介绍如何在Matplotlib中更改y轴值的方法,并
ax.xaxis.set_ticks(np.arange(start, end, stepsize)) 1. 2. The default tick formatter should do a decent job rounding the tick values to a sensible number of significant digits.默认的刻度格式设置器应将刻度值四舍五入为有意义的有效数字位数。However, if you wish to have more control over ...
