Polymarker geographic contour plot
显示 更早的评论
Is it possible to make following contour plot using Matlab? Not only for filled buble but also for other markers such as filled three angles. Thank you for help.

Yes this is possible.
I wouldn't call this a contour plot, it's really more like a bubble plot.
You can't make triangles with geobubble, but you can with geoscatter. geoscatter provides lots of the same functionality as geobubble, but you have to scale the markers yourself and you don't get a size legend (not sure what that might look like for triangles).
x=randi([20 50],50,1);
y=-randi([70 130],50,1);
s=rand(50,1)*300;
c=randi(8,50,1);
figure
geoscatter(x,y,s,c,'filled')
colormap(jet(8))
colorbar('location','southoutside','Ticks',linspace(1,8,9))
figure
geoscatter(x,y,s,c,'^','filled')
colormap(jet(8))
colorbar('location','southoutside','Ticks',linspace(1,8,9))

You can pass in the cc values for color and they will show up on the colorbar, and you can multiply them by some value to make them appropriate for size (or use the rescale button to choose the minimum and maximum size). There isn't a simple way to make a size legend.
t=readtable('data.xlsx');
geoscatter(t.Lat,t.Lon,rescale(t.CC,50,300),t.CC,'^','filled');
colormap(turbo)
c=colorbar('Location','southoutside');
xlabel(c,'Correlation Coefficient')
