i have created a scatter plot with scatter3. now without clearing this plot I need to draw a line in the same graph. when I put plot3 after scatter3 it clears the plot and then gives me the plot3 graph without the scatter points

Use the hold (link) function to plot both to the same axes.

figure
scatter3( ... )
hold on
plot3( ... )
hold off
grid on

How can I plot with scatter(X,Y,pointsize,Z,'filled') using '-o' plot lines? Only uses circles.

@Cristián Vera — Use plot rather than scattter to plot lines (with or without markers). What you want to do is not obvious, so perhaps using both (with the hold function) will do what you want. Experiment!
