Question

我在以下代码上遇到了问题（我切出了大块，但我可以将它们重新添加–这些看起来很重要）。在我的主代码中，我建立了一个绘图（“ sectionizePlot”），它是另一个晶须绘图（https://bokeh.pydata.org/en/latest/docs/user_guide/examples/plotting_whisker.html）的简单变体。我正在寻找动态更新。在同一脚本中，我使用的是热图（“ ModifiedGenericHeatMap”），该图可以正常更新。
有什么想法可以更新我的晶须图吗？更新ColumnDataSource似乎不起作用（这很有意义）。我想我在将每个圆/点分别添加到绘图上时遇到了问题。一种想法是每次都清除图并手动将点添加到图中，但是每次都需要清除，我不确定该怎么做。
任何帮助，将不胜感激。我只是一个卑微的科学家，试图在医疗研究中利用Bokeh。
