You can change how a column of data appears on graphs and throughout the program using the Options tab.
Style
Point Protectors mark every Nth point with a shape designed to help view the graph. By default, point protectors are turned off. They can be turned on in the Graph Options window.
Display
Choose how many point protectors will be displayed on the graph. You may want to reduce the number of point protectors when there is a large amount of data and the point protectors overlap each other.
Auto point protector mode will place point protectors on all time-based points if there are fewer than eight points; otherwise there will be about eight point point protectors distributed across the graph. Non-time-based data will have every point marked with a point protector in Auto mode.

Assigns a color to the graph line and to the values in the data table.
