docs - maps have wrong default color pallete

[danton267]

They have a turquoise default color palette, instead of grey.

here only first 2 plots: https://github.com/plotly/plotly.matlab-docs/blob/main/matlab/2021-08-04-bubble-maps.md

Bellow share results for one example of each geo chart case

geoscatter function

geoplot function

geobubble function

REMARK

It is important to note that for geo charts there is an optional parameter called 'geoRenderType'. This parameter can be set to 'geo' or 'mapbox'. Geo charts by default use 'geo'.

Below I share examples using 'mapbox'

geoscatter function

lon = (-170:10:170);
lat = 50 * cosd(3*lon);
A = 101 + 100*(sind(2*lon));
C = cosd(4*lon);
geoscatter(lat,lon,A,C,'^')

fig2plotly(gcf, 'geoRenderType', 'mapbox');

geoplot function

latSeattle = 47.62;
lonSeattle = -122.33;
latAnchorage = 61.20;
lonAnchorage = -149.9;

geoplot([latSeattle latAnchorage],[lonSeattle lonAnchorage],'g-*')
geolimits([45 62],[-149 -123])

fig2plotly(gcf, 'geoRenderType', 'mapbox');

geobubble function

tsunamis = readtable('tsunamis.xlsx');

tsunamis.Cause = categorical(tsunamis.Cause);

geobubble(tsunamis,'Latitude','Longitude', ...
    'SizeVariable','MaxHeight','ColorVariable','Cause');

fig2plotly(gcf, 'geoRenderType', 'mapbox');

NOTE:

The mapbox option makes geo charts more elegant, but has limitations regarding markers (they can only be circles)

[danton267]

Noting down here that none of the axes are captured with fig2plotly().

[danton267]

tsunamis = readtable('tsunamis.xlsx');

colordata = categorical(tsunamis.Cause);

gb = geobubble(tsunamis.Latitude,tsunamis.Longitude,tsunamis.MaxHeight,colordata,'Title','Tsunamis');

gb.SizeLegendTitle = 'Max Height';
gb.ColorLegendTitle = 'Cause';

fig2plotly(gcf);

not captured properly

Yes. When I updated this functionality I wrote it down as an observation. The plotly functionalities used to create the geo charts do not allow to configure the tick labels and some other axes features

[gilbertogalvis]

tsunamis = readtable('tsunamis.xlsx');

colordata = categorical(tsunamis.Cause);

gb = geobubble(tsunamis.Latitude,tsunamis.Longitude,tsunamis.MaxHeight,colordata,'Title','Tsunamis');

gb.SizeLegendTitle = 'Max Height';
gb.ColorLegendTitle = 'Cause';

fig2plotly(gcf);

not captured properly

This issue was fixed by PR #462

Result using 'geo' as 'geoRenderType'

Result using 'mapbox' as 'geoRenderType'
