<div dir="ltr"><div>Check your settings for xyMarkLineMode and/or xyMarkLineModes. If either is set to "MarkLines", then you are drawing lines as well as markers. This is one possible explanation for longer run time and apparent increased density. In this case, I would suggest just use "Markers" for what I assume is a rather high density scatter plot.<br><br></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Thu, May 26, 2022 at 6:59 AM Dave Allured - NOAA Affiliate <<a href="mailto:dave.allured@noaa.gov">dave.allured@noaa.gov</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left-width:1px;border-left-style:solid;border-left-color:rgb(204,204,204);padding-left:1ex"><div dir="ltr"><div>My interpretation of the function documentation is that a single "curve" will be drawn for 1-D arrays, and multiple "curves" will be drawn for 2-D arrays.
