why I can not make lines instead of scatter points in 3D graphs? Is this a bug in software? Properties allow to chnage that, but after clicking OK, scattered point are still left?
You can choose Plot : 3D XYZ : 3D Trajectory to get connected points or you can choose Plot : 3D XYZ : 3D Scatter and then select Format : Plot and check the 'Connect Symbols' checkbox. The two plots are based on a basic 3D plot (and could be made identical), and will appear different due to other options which have been saved in the template.
