<div dir="ltr"><div><div><div><div>Dear Dennis,<br><br></div>I made the plot with the script you send me. As per the plot the maximum density (number density of scatter points) is confined in the centre of the plot, whereas the contour lines are showing something different.<br><br></div>What I want is the maximum value of contour with more number density points. So as per your figure the maximum contour value should fall in the centre of the scatter plot. Hope I make you understand my problem clearly.<br><br></div>Thanks in advance,<br></div>Ipsita<br><div><div><br></div></div></div><div class="gmail_extra"><br><div class="gmail_quote">On Tue, Mar 21, 2017 at 11:01 PM, Dennis Shea <span dir="ltr"><<a href="mailto:shea@ucar.edu" target="_blank">shea@ucar.edu</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="ltr"><div><div><div><div>The attached is done with random numbers. <br></div>It illustrates the process.<br><br></div><div>x, y, values are all one-dimensional arrays<br></div><div><br></div>%> ncl tst_density_scatter.ncl_v0<br><br></div>It will draw to an x11 windo.<br><br></div>HTH<br></div><div class="HOEnZb"><div class="h5"><div class="gmail_extra"><br><div class="gmail_quote">On Tue, Mar 21, 2017 at 1:56 AM, Ipsita Putatunda <span dir="ltr"><<a href="mailto:ipsita.putatunda@gmail.com" target="_blank">ipsita.putatunda@gmail.com</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><span class="m_-534305448413086549im m_-534305448413086549HOEnZb"><div dir="ltr"><span class="m_-534305448413086549m_7266334589645761016gmail-im m_-534305448413086549m_7266334589645761016gmail-HOEnZb"><div><div><div><div><div>Dear Dennis,<br></div>Thank you for your suggestions, but I have little doubt;<span class="m_-534305448413086549m_7266334589645761016gmail-m_-6116265308012608467gmail-im"><br><br> res@sfXArray = x_location_of-each_point ; [*]<br> res@sfYArray = y_location_of-each_point ; [*]<br><br></span></div>these two resources(res@sfXArray, res@sfYArray) should be monotonically increasing or decreasing, where in my case it is not.<br></div>What
