I have a set of points that I use to create a scatter plot. I would like to select the outliers and delete them graphically.

not sure this is what you had in mind ...
%Environment
envSize=4;figure; x=-envSize:0.1:envSize;y=.5*sin(x);plot(y,x,'lineWidth',10)axis([-envSize envSize -envSize envSize]);hold on;%Input
left=[0 0 1 1 1 1 1];right= [1 1 0 0 0 0 0 0];% number of ppl
nL=sum(left);nR=sum(right);%random position for ppl
maxX=envSize-1;minX=2*max(y);maxY=envSize-1;minY=-(envSize-1);pL = [-(minX + (maxX-minX) .* rand(nL,1)), (minY + (maxY-minY) .* rand(nL,1))]pR = [(minX + (maxX-minX) .* rand(nR,1)) , (minY + (maxY-minY) .* rand(nR,1))]% plot
scatter(pL(:,1),pL(:,2),'filled','SizeData',200)alpha(.5)scatter(pR(:,1),pR(:,2),'filled','SizeData',200)alpha(.5)the output looks like this
MATLAB: How to edit the plot of the logged signals in Time Series Tools GUI in Simulink 7.1 (R2008a)
The ability to use the Time Series Tools GUI to directly edit logged signals displayed in the GUI is not available in Simulink 7.1 (R2008a).
As a workaround, MATLAB plots for individual signals can be generated by clicking on the "Display" button on the time series data tab in the GUI. These plots can be manipulated in the same manner as any other MATLAB plot.
