<body class='hmmessage'><div dir='ltr'>Hi:<br>First of all i want to ask you if time = [63602,63602.05,63603,63603.5,63604,63606] is correct. As you may notice, the first two values are too near... so in the plot the tics appear overlapped... if you use time = [63602,63602.5,63603,63603.5,63604,63606] the plot's tics become clearer...<br><br>The second question is how near this tics are supposed to be in the worst case? for example, if your time conssists of values sepparated about 0.05, you could create a new vector containing the positions of the tics, that exclude too near values... I mean:<br><br>time = [63602,63602.05,63602.09,63603.5,63604,63606]<br>values = [1,2,3,4,5,7]<br><br>function convertedtime = timestring(UT) //converts UT<br> h=int(UT/3600);<br> UT=UT-h*3600;<br> m=int(UT/60);<br> UT=UT-m*60;<br> if UT < 10 then<br> convertedtime = string(h) + ":" + string(m) + ":0" + string(UT);<br> else<br> convertedtime = string(h) + ":" + string(m) + ":" +string(UT);<br> end<br>endfunction<br><br> timeTics=time(1)<br> for i=1:length(time)<br> if(abs(timeTics($)-time(i))>=0.5)<br> timeTics=[timeTics;time(i)]<br> end<br> end<br><br>newtime = timestring(timeTics);<br>plot(time,values);<br>a=gca();<br>ticks = a.x_ticks<br>ticks.labels=newtime<br>ticks.locations=timeTics<br>a.x_ticks=ticks<br><br>This may be non optimall solution, but may work<br><br><br><br><div><hr id="stopSpelling">Date: Wed, 9 Dec 2015 18:37:37 +0100<br>From: flotschos@gmail.com<br>To: users@lists.scilab.org<br>Subject: [Scilab-users] Converting UT to Standard Time<br><br><div dir="ltr">Hi,<div>I have a problem.
