<div dir="ltr"><div>You have to be careful when plotting exact values (i.e., integers or floats with all zeros following the decimal point). Even a contour plot will plot a blanket shade of color if you select a contour level that exactly matches the values in the field you're plotting. Since you are constraining your fields to all be 0 and 1 and also setting the contour intervals as those values, that's probably what is happening. I recommend picking an intermediate value instead such that the exact value falls cleanly in the middle of a contour interval instead of right on the edge.</div><div><br></div><div>The other possibility is the use of the background color (0) for the "don't color this area" region. You might consider trying a clear color instead. Just define a new one with no opacity, such as 'set rgb 20 0 0 0 0' and use that color number instead. <br></div><div><br></div><div>Jeff Duda<br></div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Tue, Dec 29, 2020 at 8:21 PM UwBe International - Severe Weather Research <<a href="mailto:info@uwbeinternational.org">info@uwbeinternational.org</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">

<p>Hi Everyone<br>
<br>
I try plot/draw more variables on the same map.<br>
I have try the following:<br>
<br>
'define
prob=const(const(maskout(cape255_0mb,cape255_0mb-500),1.0),0,-u)*const(const(maskout(no4LFTX180_0mb,-2-no4LFTX180_0mb),1.0),0,-u)'<br>
'define prb=const(const(maskout(prob,prob-1),1.0),0,-u))'<br>
<br>
'set clevs 0 1'<br>
'set ccols 0 7'<br>
'd prob'</p>
<p>'define l1=const(const(maskout(scp,scp-1.5),1.0),0,-u))'<br>
'define level1=const(const(maskout(l1,l1-1),1.0),0,-u))'<br>
<br>
'set clevs 0 1'<br>
'set ccols 0 2'<br>
'd level1'</p>
<p>The Problem is now, that i only get red areas from level1 on the
Map and nothing from 'd prob'.<br>
If i comment out 'd level1' and only have 'd prob', then i will
get all yellow areas. <br>
<br>
How i can draw both?<br>
I'm confused! <br>
</p>
