There are times when that would be true, for example\nsequential years or months, which is the example shown on page 18 of the\nstandards guide (any kind of ordered factor would also work). But the\nstandards still suggest no lines.\n\nNote that addAxisLabels will add the ticks in this case--just set ticks to\nTRUE and labels to FALSE.\n\n\n\nOn Thu, Oct 22, 2015 at 1:33 PM, Laura DeCicco <notifications@github.com>\nwrote:\n\n> The root cause of this question was because of a column \"Period\" returned\n> from rloadest that has \"WY 2006\", \"WY 2007\" etc.\n>\n> —\n> Reply to this email directly or view it on GitHub\n> <https://github.com/USGS-R/smwrGraphs/issues/25#issuecomment-150315633>.\n>\n"}}
