<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri",sans-serif;color:#1F497D">Hi everyone,<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri",sans-serif;color:#1F497D"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri",sans-serif;color:#1F497D">My apologies. I should have been more specific about what I am trying to do. I want to generate some notional antenna radiation pattern plots showing main lobe,
back lobe, and side lobes’ sizes (both peak gain and beamwidths). These plots are normally done with radial values in dB from some negative value up to zero or some positive value. The angle values on these plots are typically marked in degrees around the
perimeter.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri",sans-serif;color:#1F497D"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri",sans-serif;color:#1F497D">I have found some workarounds to get something approximating a polar radiation pattern plot. I used the <title> tag to mark +90 degrees, <xaxis> to mark -90,
and yaxis to mark 180, but that does not give great resolution. (The plot grid only shows radii every 30 degrees.)<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri",sans-serif;color:#1F497D"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri",sans-serif;color:#1F497D">Likewise, I used the axis xformat and yformat parameters, in conjunction with the xtics and ytics tags, to mark radial magnitudes, but they only work for radial
values from 0 to some positive number. If there is a way to do a logarithmic scale for the radial values, I cannot figure it out.

<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri",sans-serif;color:#1F497D">After searching through the LON-CAPA Author manual and the gnuplot manual, I think this may be as close as I can get to the equivalent of a MATLAB (theta, rho)
polar plot. It appears to be a limitation of gnuplot, not LON-CAPA.<o:p></o:p></span></p>

<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri",sans-serif;color:#1F497D">Does anyone know for sure? Maybe there is a way to do this in Geogebra, but I think I may have to compromise for now to get a problem constructed.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri",sans-serif;color:#1F497D"><o:p> </o:p></span></p>

out how to turn off the Cartesian grid, but need to display angles from 0-360 or -180 to +180 around the circle instead of x-y coordinates.

<p class="xmsonormal">Hi,<o:p></o:p></p>
<p class="xmsonormal"> <o:p></o:p></p>
<p class="xmsonormal">Has anyone done polar-format gnuplots in LON-CAPA? Would you be willing to share an example? This is my first foray into polar gnuplots. I am having trouble getting the angle to display around the perimeter. It’s rendering x- and y-axis
values instead of angle and radius values.<o:p></o:p></p>
