Please find the enclosed figure. Tick marks are labeled as 1, 5, 10, 15, 20, 30, 40, 50, 60, 70. The label is irregular, but I have no idea how to make the intervals between them irregular as well. For instance, the distance between 5 and 10 should be only half that between 20 and 30. Is it possible to do this in NCL? Thank you very much!</div><div style="font-size:12.8px">Best, </div><span class="HOEnZb"><font color="#888888"><div style="font-size:12.8px">Hui Ding </div><div style="font-size:12.8px"><br></div><div style="font-size:12.8px"><br></div></font></span></div>
