Hello,

I need to visualize a watertank in Matlab. I have the height of the water in a 1x1000 array and it needs to change over the time of 1:1000.

Also I need a steady yline that doesn't change.

Is there a build in funktion? can I use the addpoints funktion?

Have you looked into AppDesigner?

在 MATLAB Online 中打开

You want something like this?

% Sample data
x = 0:360;
y = sind(x);
% Create the sine curve with one marker
h = plot(x, y, 'Marker', 'o', 'MarkerIndices', 1);
% Create the horizontal line
L = yline(y(1));
for whichPoint = 2:length(y)
    % Change the height of the horizontal line
    L.Value = y(whichPoint);
    % Change which point in the sine curve has the marker
    h.MarkerIndices = whichPoint;
    % Give MATLAB a chance to redraw the screen
    drawnow expose
end
