you pointed out. <o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US" style="font-size:11.0pt;font-family:"Calibri",sans-serif;color:#1F497D;mso-fareast-language:EN-US">I would find hardly acceptable, from common excel coming users point of view, that Scilab can’t offer at least a raw feature
to manage this very common task when processing data with timestamps over weeks, months, years therefore I proposed this raw approach.<br>

DD.hh:mm, hh:mm:ss according to the max span of the level of zoom in the current display.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US" style="font-size:11.0pt;font-family:"Calibri",sans-serif;color:#1F497D;mso-fareast-language:EN-US">If the axis is zoomed or the window size changed, call again labxdtv so that it re-graduates this x-axis (according to
datenum values) and convert the new x-ticks into appropriate datevec and automatic choice of the format YY/MM/DD , MM/DD.hh, DD.hh:mm, hh:mm:ss according to the max span of the x-axis.<br>

<p class="MsoNormal"><span lang="EN-US" style="font-size:11.0pt;font-family:"Calibri",sans-serif;color:#1F497D;mso-fareast-language:EN-US">In the above example 17, 18 and 19 are years , not days so it’s rather normal display. At this level of zoom we have YY/MM/DD
but if you manually zoom and change the window size and call again labxdtv() afterwards, you may obtain the following, which allow to see when you :<o:p></o:p></span></p>

directly that the format is automatically adapted to “MM/DD.HH” It’s not so common format but acceptable to analyze the data on the fly.<o:p></o:p></span></p>
