Anomalies (W/m2) are being plotted. However, the values could be anything .. not necessarily 'heat'.<br><br></div><div>Given that the y-axis is 'YEAR' and the x-axis is 'day', a more appropriate classification would be a 'time-time' (year-day) plot.<br></div><div><br>---<br></div><div>re: "Is this possible to do in NCL?"<br><br>Yes, of course NCL can do it. Likely any tool could be used. <br>Actually, the plot looks like an NCAR Graphics plot.<br>---<br></div><div>re: "the sample data"<br><br></div><div>The sample data file contains <b>monthly</b> precipitation.
