I've got a time series on the x axis labeled with dates formatted with set format x "%m/%d". Is there a way to remove the leading zeros from both the month and the day to save space, i.e. 7/8, not 07/08? I don't see %m & %d equivalents without leading zeros. My guess that it could be done with some sprintf or strftime statement, but I'm not sure how. Thanks.
