Hi Grace,<br>
<br>
do you mean how to plot a legend at the lower right box edge of the
scatter plot containing the marker and data labels?<br>
<br>
Here is an example how to create a scatter plot with a user defined
legend:<br>
<br>
<font color="#3333ff"><tt>;---------------------------------------------------</tt><tt><br>
</tt><tt>; set_xy_markers.ncl</tt><tt><br>
</tt><tt>;---------------------------------------------------</tt><tt><br>
</tt><tt>begin</tt><tt><br>
</tt><tt><br>
</tt><tt> npts = 100</tt><tt><br>
</tt><tt> data1 = random_uniform(0.1,50,npts)</tt><tt><br>
</tt><tt> data2 = random_uniform(0.1,50,npts)</tt><tt><br>
</tt><tt> x = ispan(1,npts,1)</tt><tt><br>
</tt><tt> </tt><tt><br>
</tt><tt> print("min/max data = " + min(data1) + "/" +
max(data1))</tt><tt><br>
</tt><tt> print("min/max data = " + min(data2) + "/" +
max(data2))</tt><tt><br>
</tt><tt><br>
</tt><tt>;-- create data array containing data1 and data2</tt><tt><br>
</tt><tt> data = new((/2,npts/),typeof(data1))</tt><tt><br>
</tt><tt> data(0,:) = data1</tt><tt><br>
</tt><tt> data(1,:) = data2</tt><tt><br>
</tt><tt><br>
</tt><tt>;-- set explicit labels for legend</tt><tt><br>
</tt><tt> labels = (/"data 1","data 2"/)</tt><tt><br>
</tt><tt><br>
</tt><tt>;-- open workstation</tt><tt><br>
</tt><tt> wks = gsn_open_wks("x11","plot_xy_markers")</tt><tt><br>
</tt><tt> </tt><tt><br>
</tt><tt>;-- set resources</tt><tt><br>
</tt><tt> res = True</tt><tt><br>
</tt><tt> res@gsnMaximize = True
;-- maximize plot output</tt><tt><br>
</tt><tt> </tt><tt><br>
</tt><tt> res@tiMainString = "Marker Plot"
;-- add title</tt><tt><br>
</tt><tt> </tt><tt><br>
</tt><tt> res@trYMinF = min(data1)-20.
;-- y-axis minimum to have enough space for legend</tt><tt><br>
</tt><tt> res@trYMaxF = max(data1)+20.
;-- y-axis maximum</tt><tt><br>
</tt><tt><br>
</tt><tt> res@tmLabelAutoStride = True
;-- use nice tick mark labels</tt><tt><br>
</tt><tt><br>
</tt><tt> res@xyMarkLineModes = (/"Markers","Markers"/)
;-- set mark line mode for both variables</tt><tt><br>
</tt><tt> res@xyMarkers = (/ 10, 16/)
;-- choose marker types </tt><tt><br>
</tt><tt> res@xyMarkerColors = (/"red","blue"/)
;-- choose marker colors</tt><tt><br>
</tt><tt><br>
</tt><tt> res@lgJustification = "TopRight"
;-- position of legend</tt><tt><br>
</tt><tt> res@lgLabelFontHeightF = 0.01
;-- legend label font size</tt><tt><br>
</tt><tt> res@lgItemOrder = (/1,0/)
;-- reverse the legend</tt><tt><br>
</tt><tt> res@xyExplicitLabels = labels
;-- use explicit legend labels</tt><tt><br>
</tt><tt> </tt><tt><br>
</tt><tt> res@pmLegendDisplayMode = "Always"
;-- display legend always</tt><tt><br>
</tt><tt> res@pmLegendWidthF = 0.10
;-- legend width</tt><tt><br>
</tt><tt> res@pmLegendHeightF = 0.08
;-- legend height</tt><tt><br>
</tt><tt> res@pmLegendOrthogonalPosF = -0.24
;-- move legend up</tt><tt><br>
</tt><tt> res@pmLegendParallelPosF = 0.98
;-- move legend right</tt><tt><br>
</tt><tt><br>
</tt><tt>;-- create the plot</tt><tt><br>
</tt><tt> plot = gsn_csm_xy(wks,x,data,res)</tt><tt><br>
</tt><tt><br>
</tt><tt>end<br>
