Question

我是新来的。我想知道更改pandas_bokeh或其他库中允许使用地图创建仪表板的点的外观的可能性（我在SVG中有一个图标）。我想更改变量my_hover.tooltips = [('SIEC', '@siec')]的图标，

我尝试在图表上使用hovertool_string运行Bokeh。但我不知道如何在地图上进行更改。

我没有任何错误消息，我只是不知道该怎么办...

如果您想用图像替换地图上的点，可以像本例中那样使用image_url（解决方案是针对Bokeh v1.1.0的，因为我一开始不清楚您的目标是{ {1}}）。要固定图像的大小，请使用pandas_bokeh

h_units = 'screen', w_units = 'screen'

在SVG pandas_bokeh上更改点在地图上的外观
