问题 I have the following heatmap made by Holoviews. I need to change x ticks to change the period of x ticks.

However you can change the doFormat function of xaxis.formatter before draw the plot. After run the following cell: from bokeh.models import CustomJS import holoviews as hv hv

问题 I recently tried running the 1-Introduction.ipynb notebook in holoviews-examples in jupyterlab 0.32.1 with bokeh 0.12.16, holoviews 1.10.7 and jupyterlab_pyviz 0.5.2 installed. The plots don't seem to be rendered in a cell, however; moreover, I can't move the plot around or delete it (see the below example for when I run the first cell in the notebook containing a scatter plot): Any thoughts as to what could be causing this? I don't have this problem if I use bokeh directly. 回答1: Per

Setting x and y labels with holoviews

由 房东的猫 提交于 2019-12-07 01:40:50
问题 I would like to change the labels on the x and y axis on a figure from holoviews to be something other than the internal variable name. It seems the typical way to affect the axis labels is to change the variable names themselves to the label. This is rather inconvenient if you want complex labels, especially if you are frequently converting from other complex data objects like pandas dataframes. Is there a general way to either: (A) change x and y labels of a figure as or after you plot it

How do i automatically update a dropdown selection widget when another selection widget is changed? (Python panel pyviz)

问题 I have a Select widget that should give a different list of options whenever another Select widget is changed, so it updates whenever this other Select widget changes. How do I this in the example code below? _countries = { 'Africa': ['Ghana', 'Togo', 'South Africa'], 'Asia' : ['China', 'Thailand', 'Japan'], 'Europe': ['Austria', 'Bulgaria', 'Greece'] } continent = pn.widgets.Select( value='Asia', options=['Africa', 'Asia', 'Europe'] ) country = pn.widgets.Select( value=_countries[continent
