Access all objects with tag 'PlotMatrixScatterAx' using findobj
ax = findobj(fh,'Tag','PlotMatrixScatterAx');
- Run for loop for all axes and access only thoses axes which have two childrens
- Access the 2nd's children's Xdata and Ydata ( the scatter which is actually line plot with marker 'o')
- Save it in Xdata var and do similar for Ydata
- Now the first children of axes is the line bw two points. access two points Xdata and Ydata which are of size 2. Now interpolate all the Xdata points of children 2 (the scatter) so you can apply threshold. (we have line value for each corresponding Xdata of scatter)
- then apply condition ( currently) i am accessing points below line and replacing points above line with NaN
- Replace 2nd children's ydata with new generated ydata
for ii = 1:length(ax)
if(length(ax(ii).Children)>1)
Xdata=ax(ii).Children(2).XData;% scatter Xdata
Ydata=ax(ii).Children(2).YData;% scatter-Ydata
Thdata=interp1(ax(ii).Children(1).XData,ax(ii).Children(1).YData,Xdata);% interpolate limits
ind =Ydata>Thdata;
Ydata(ind) = NaN;
ax(ii).Children(2).YData = Ydata;
end
