Hi all,
I am creating a Choropleth map using geojson. All works fine except the paper background. All is fine except for two issues:
- I cannot remove the grey/blue-ish background despite using
paper_bgcolor='rgba(0,0,0,0)'. - Somehow I cannot properly center the title over the map. Is there a way to center it over the map minus the scale?
Currently using: pandas and geopandas, python3.6, Jupyter notebook
Below are code and image.
Any pointers are appreciated. Many thanks!
title = 'Colorado county data on a map'
mapping = go.Choropleth(geojson=co_geo,
locationmode='geojson-id',
featureidkey='properties.GEOID',
locations=county_month['GEOID'][mask1],
z=county_month['datacount'][mask1],
text=county_month['county'][mask1],
hoverinfo='text+z',
zmin=1,
zmax=county_month['datacount'][mask1].max(),
colorscale='Sunsetdark')
mapping2 = go.Choropleth(geojson=co_geo,
locationmode='geojson-id',
featureidkey='properties.GEOID',
locations=county_month[mask2]['GEOID'],
z=county_month['datacount'][mask2],
text=county_month['county'][mask2],
hoverinfo='text+z',
colorscale='Greys',
zmin=0,
zmax=100,
showscale=False)
data = [mapping, mapping2]
layout=go.Layout(title=title,
font={'size':18,
'color':'#7f7f7f',
'family':'Courier New, monospace'})
fig = go.Figure(data=data, layout=layout)
fig.update_geos(projection_type='mercator',
fitbounds='locations')
fig.update_layout(title={
'x':0.4,
'xanchor':'center'
})
fig.update_layout(margin={'r':0, 't':50, 'l':0, 'b':0, 'pad':0},
paper_bgcolor='rgba(0,0,0,0)',
plot_bgcolor='rgba(0,0,0,0)')
pyo.plot(fig,filename=filename)
This is how it looks like.
