Dear all,</div>

I am encountering an issue when using a similar script to <a href="https://www.ncl.ucar.edu/Applications/Scripts/rose_5.ncl" id="m_2584619776754372661OWA3e9bd0f5-9523-623f-3ff1-a5450f7fc8c9" style="margin:0px;text-align:left" target="_blank">
https://www.ncl.ucar.edu/Applications/Scripts/rose_5.ncl</a> to plot a wind rose. The circles in the plot seem to appear randomly, with two or three circles being generated.</div>

Could you please advise if there are any functions or settings that can ensure the number of circles, either two or three?</div>
