Draw from cartesian xy-data a spiral

Hello, i have cartesian data in x and y direction of a spiral path movement of a robot over time.

So I want now plot this spiral in matlab. But then I receive a wave.

How can I plot my data to get the spiral. The first column is the time, second x-data, third y-data. Unit of time is millisecond and movement is in millimetre.

Attached is the data, my matlab script:

M = readmatrix('spiral')
subplot(2,1,1)
plot(M(:,1)/1000,M(:,2));
hold on
subplot(2,1,2)
plot(M(:,1)/1000,M(:,3));

M = readmatrix('spiral');
plot(M(:,2),M(:,3)); % x, y
