I have 2 subplots in my figure and a legend that has been manually repositioned below the plots. May I know if it is possible to
1. Increase the spacings between each legend entry (thus making the width of the entire legend wider) ?
2. Increase the 'length' of the marker of each legend (also making the width of the entire legend wider). For example, instead of SLIC having a marker of -O- , I would like it to be ---O---
