Can I show a cursor on Compose Plots?

Mattia_Setti

Hi Altair community,

 

my question is about plotting curves in Compose with a cursor moving through their points. Is it possible?

For example, if I plot a track with latitude and longitude, could I show a cursor moving along it like a car doing a lap?

Thanks for your time!

What about testing this example?

clear; close all; clc

x = 0:0.1:2*pi;
y = sin(x);

for i = 0:0.1:2*pi
    plot(x,y);
    ylim([-1.2 1.2]);
    xlim([0 2*pi]);
    hold on;
    scatter(i,sin(i),'r','markersize',10);
    text(i,sin(i),['x: ' num2str(i) ', y: ' num2str(sin(i))]);
    pause(0.1);
    hold off;
end

Regards,

Roberta
