How to improve saving a scatter plot from three arrays with size 1*508654896

1 vue (au cours des 30 derniers jours)
using 3 arrays R,S and T I want to make a scatterplot,but it takes a lot of time to save the scatterplot and sometimes crashed. How can I improve it?
bb= find(R>=0.2 & R <0.4);
x2 = S(bb);
y2 = T(bb);
figure(2)
scatter(x2,y2,'MarkerFaceColor','b','MarkerEdgeColor','b');
saveas(gcf,'420bbh.tiff', 'tiffn') saveas(gcf,'420bbh.fig')

I think you need to consider another kind of plot. Your monitor doesn't even have that many pixels!

most of these pixels are nan

Then remove them before scattering!
Otherwise, they still need to be transmitted.
Here's one way to remove:
idxNan = isnan(x)|isnan(y);
x(idxNan) = [];
y(idxNan) = [];
