Based on your template substitutions, it looks like there is one data file for each hour. If you have 24 files, then you need to change your TDEF size to 360. </div><div><br><blockquote type="cite"><div dir="ltr"><div><div><div><div><div><br></div>I made already script program to plot one hour data as follow :<br>

<br> <br><br></div><b>My question is, how to plot 24 hours data directly??<br></b></div><b>I mean. when I execute program, I can get 24 figures in one time…</b><br></div></div></div></blockquote><div><br></div><div>Well, I'm not entirely clear on what it is you want to do, but ...</div><div>If you change your TDEF as I mentioned above, then you build a loop like this:</div><div><br></div><div>t=1</div><div>day=1</div><div>while (t<360)</div><div> 'set t 't</div><div> 'R2=log10(ave(pow(10,ref/10),t+0,t+15))</div><div> 'clear'</div><div> <put your display commands for drawing R2 here></div><div> 'printim day'day'.png'</div><div> day=day+1</div><div> t=t+15</div><div>endwhile</div>'close 1'</div><div><br></div><div>Then you get 24 images named (day1.png, day2.png, day3.png…) each with an average for 15 successive time steps. </div><div>Hope that helps.</div><div>--Jennifer</div><div><br><blockquote type="cite"><div dir="ltr"><div><div><br></div>Thank you very much for your help...<br><br>
