geoviews

问题 I have 2 shapefiles for the UK: In [3]: # SHAPEFILE 1: ...: # WESTMINISTER PARLIAMENTARY CONSTITUENCY UK SHAPEFILE ...: shapefile1 = "../Westminster_Parliamentary_Constituencies_De ...: cember_2017_UK_BSC_SUPER_SMALL/Westminster_Parliamentary_Constituencies_ ...: December_2017_UK_BSC.shp" In [4]: # SHAPEFILE 2: ...: # LAD19 UK SHAPEFILE ...: shapefile2 = "../03_Maps_March_2020/level3_LAD19_CONTAINS_4_L ...: EVELS_OF_DETAIL/Local_Authority_Districts_December_2019_Boundaries_UK_BU ...: C/Local

问题 I'm trying to use geoviews to display a path. I can get it to display ONLY the points properly: import numpy as np import geoviews as gv import cartopy.crs as ccrs import pandas as pd hv.extension('bokeh') coord_system = ccrs.UTM(17) userLine = [[ 501386.89237725, 3026047.23276743], [ 502233.40219658, 3030363.86891928], [ 497065.22714886, 3031309.6654351 ], [ 499260.08171301, 3027147.9437062 ], [ 494678.08475863, 3026891.08691589], [ 494971.32963864, 3025188.1383645 ], [ 496475.86909916,

问题 I am trying to do something similar to the OP in this question Geoviews: Add a slider to choropleth map, but it wasn't fully answered. In brief, I have a GeoDataFrame like this: I would like to visualise pre_anom by geometry in a GeoViews map, but I have multiple years for each geometry element. I'd like to have a slider created automatically for the extra kdim year, but if I specify year as a kdim like so: gv.Polygons(gdf, kdims=['year'], vdims=['pre_anom']).opts(width=600, height=600, tools

问题 I am putting together an interactive dashboard using the pyviz ecosystem. One feature of the dashboard is that the underlying data may change based on a widget selector. Below is an example code showing the issue I have with getting the time widget slider to appear: Package Versions : panel: 0.5.1 param: 1.9.0 holoviews: 1.12.3 geoviews: 1.6.2 Example : import xarray as xr import panel as pn import numpy as np import param as pm import holoviews as hv import geoviews as gv from matplotlib

问题 I'm working on GeoViews and I'd like to know if we could have a slider as an input for the choropleth map in GeoViews. I've another variable in gdf, which is year. Is it possible to have a slider to show year wise Total_Crimes? Edit: Added more information: gdf dataframe has following variables. beat_num Year Total_Crimes beat district sector geometry 111 2012 1449 1 01 1 POLYGON ((-87.62451050462798 41.88829675314376... 111 2013 1645 1 01 1 POLYGON ((-87.62451050462798 41.88829675314376...
