Dear Gabriel,<br><br>In order to obtain the total precipitation within a month, you can just 'define acc=sum(pcp, t=1, t=31)'.<br>If I really understand what you want is that you would like to display both daily and accumulation within one graphic. If so, it's a little bit tricky but what I can suggest is that if you want to display both within one graphic, try to set gxout linefill since linefill can deal with 2 variables, then go back to set gxout line so it will be something like:<br>
<br>'sdfopen <a href="http://file.nc">file.nc</a>'<br>'set lat -23'<br>'set lon -45'<br>'set t 1 31'<br>'define acc=sum(pcp, t=1, t=31)'<br>'set gxout linefill'<br>'set lfcols 0 0' (----> this is black color and you can refer to <a href="http://www.iges.org/grads/gadoc/colorcontrol.html">http://www.iges.org/grads/gadoc/colorcontrol.html</a>)<br>
'd pcp;acc' (up til here, you have only the x and y value, without the graphs, so you need to plot the graph)<br>'set gxout line'<br>'set ccolor 3'<br>'d pcp'<br>'set ccolor 5'<br>
'd acc'<br><br>Hope this can help,<br><br>Regards,<br><br>Serge<br><br><div class="gmail_quote">2011/6/21 gabriel gavinho <span dir="ltr"><<a href="mailto:gavinho.gabriel@gmail.com">gavinho.gabriel@gmail.com</a>></span><br>

<div>My problem is that I need to continually sum the daily valeus so I can achive the total precipitation within a month but in a way I can present an increasing line in over the daily values.</div><div>I hope I could make it clear and I really appreciate your help</div>

<blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">Dear Gabriel,<br><br>What do you mean by "in the same graphic"? because I think it will depends on that. For your precipitation data, if you set your gxout to shaded, I think you won't see both values, but if you set your gxout, for example to contour, you'll be able to see both.<br>
<br>Let's say your precipitaion variable is "pcp". It will be something like:<br>'sdfopen <a href="http://file.nc" target="_blank">file.nc</a>'<br>'set gxout contour'<br>'define acc=sum(pcp, t=1, t=31)'<br>
'd pcp'<br>'d acc'<br><br>So if you need for the day 17, just set t to 17 by adding 'set t 17' right after 'sdfopen...'<br>In addition, you can write your accumulation variable to your file using 'set sdfwrite <a href="http://file.nc" target="_blank">file.nc</a>' followed by 'sdfwrite acc'.<br>
Maybe the following will give you more info.<br><br>I quote from Bob Kuligowski:<br><br>"GrADS can produce numerous types of file displays using gridded data using set gxout:<br><br>bar (bar chart) <br>line (line graph)<br>
barb (wind barbs) <br>linefill (color fill between two lines)<br>contour (contour plot) <br>scatter (scatter plot)<br>errbar (error bars) <br>shaded (shaded contour plot)<br>grfill (shaded grid boxes) <br>
stream (wind streamlines)<br>fgrid (grid boxes shaded for specified values) <br>vector (wind vector arrows)<br>grid (grid boxes with printed values)"<br><br>Hope it can help,<br><br>Regards,<br><br>Serge<br>
