Hello, I am a beginner with MATLAB but I am trying to create a scatter plot that plots data points one by one from 2 different data sets simultaneously, creating an animated scatter plot. I have code to create the scatter plot but only with one data set, I am unsure how to add in the second set of data. For example, the data I am plotting are the x and y coordinates of a drill held in one hand during surgery and a suction irrigator held in the other hand - I want to follow the scatter dots as if they are the hands.

Here is what I currently have.

Drill = readtable('matlab_test');
X = Drill{:,1};
Y = Drill{:,2};
plot1 = scatter(X(1),Y(1),60,'.');
axis([-2.5 2.5 -1.5 1.5]) 
for k=2:length(X) 
    plot1.XData=X(k); 
    plot1.YData=Y(k);
    pause(0.03);    
end
