带有 x 范围滑块的 Y 轴自动缩放 [英] Y-axis autoscaling with x-range sliders in plotly

问题描述

Afaik，使用 x 范围滑块时，y 轴无法自动缩放.Y 范围是相对于整个 x 范围的 y 值选择的，并且在放大后不会改变.这对于波动时期的烛台图尤其烦人.当您使用 x-range 滑块放大时，您基本上会得到扁平的烛台，因为它们的波动只覆盖了初始范围的很小一部分.在做了一些研究之后，这里似乎取得了一些进展:https://github.com/plotly/plotly.js/pull/2364.任何人都知道 plotly.py 是否有可行的解决方案?感谢您的宝贵时间.

Afaik, y-axis cant be made to auto scale when using x-range sliders. Y range is chosen with respect to the y values of the whole x range and does not change after zooming-in. This is especially annoying with candlestick charts in volatile periods. When you zoom-in using x-range slider, you essentially get flat candlesticks as their fluctuations only cover a very small part of the initial range. After doing some research it seems that some progress has been made here: https://github.com/plotly/plotly.js/pull/2364. Anyone knows if there is a working solution for plotly.py ? Thanks for your time.

推荐答案

如果有帮助，我在 yaxis 上使用 fixedrange = False，以便能够手动缩放并将窗口调整到合适的 y 范围:

If it can help, I am using fixedrange = False on yaxis, to be able to zoom manually and adapt the window to the suited y range:

yaxis = dict(
     fixedrange = False
)
