Yongzuo,

Try setting lgres@lgItemType to "MarkLines" which will turn it into both lines and markers. Or, if you need to control individual legend lines, then use lgres@lgItemTypes with lgres@lgMonoItemType set to False.

If you are using the legend that is associated with an XY plot, then if you've set xyMarkLineMode to "MarkLines", the legend lines should automatically have markers and lines.

Please see the legend examples page for more help:
