<div dir="ltr">Hi Voula,<div>NCL (for some reason) has a hard limit to the number of tickmarks that can be drawn on a plot. 616 is a very large number of tick mark labels. Even if you could draw 616 tick mark labels you wouldn't likely be able to read them as they would all be running into one another. Do you have to label all 616? You can likely get around this issue by manually overlaying plots (each with different ranges of tickmarks) onto one another, but that would be very tedious. </div><div><br></div><div><span style="color:rgb(34,34,34);font-family:arial,sans-serif;font-size:small;font-style:normal;font-variant-ligatures:normal;font-variant-caps:normal;font-weight:400;letter-spacing:normal;text-align:start;text-indent:0px;text-transform:none;white-space:normal;word-spacing:0px;background-color:rgb(255,255,255);text-decoration-style:initial;text-decoration-color:initial;float:none;display:inline">To get NCL to draw the tickmarks you will have to reduce the number of them below 256.</span></div><div><span style="color:rgb(34,34,34);font-family:arial,sans-serif;font-size:small;font-style:normal;font-variant-ligatures:normal;font-variant-caps:normal;font-weight:400;letter-spacing:normal;text-align:start;text-indent:0px;text-transform:none;white-space:normal;word-spacing:0px;background-color:rgb(255,255,255);text-decoration-style:initial;text-decoration-color:initial;float:none;display:inline"><span><br></span></span></div><div><span style="color:rgb(34,34,34);font-family:arial,sans-serif;font-size:small;font-style:normal;font-variant-ligatures:normal;font-variant-caps:normal;font-weight:400;letter-spacing:normal;text-align:start;text-indent:0px;text-transform:none;white-space:normal;word-spacing:0px;background-color:rgb(255,255,255);text-decoration-style:initial;text-decoration-color:initial;float:none;display:inline"><span>If you have any further questions please respond to the ncl-talk email list.</span></span></div><div><span style="color:rgb(34,34,34);font-family:arial,sans-serif;font-size:small;font-style:normal;font-variant-ligatures:normal;font-variant-caps:normal;font-weight:400;letter-spacing:normal;text-align:start;text-indent:0px;text-transform:none;white-space:normal;word-spacing:0px;background-color:rgb(255,255,255);text-decoration-style:initial;text-decoration-color:initial;float:none;display:inline"><span>Adam </span></span></div></div><div class="gmail_extra"><br><div class="gmail_quote">On Mon, Apr 23, 2018 at 10:46 AM, Paraskevi Vourlioti <span dir="ltr"><<a href="mailto:p.vourlioti@fz-juelich.de" target="_blank">p.vourlioti@fz-juelich.de</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">dear NCL Users,<br>
<br>
I used gsn_csm_xy to plot an XY plot. On the X axis i have 616 values<br>
which i would like to correspond to some numbers on the top x axis. So,<br>
i used this :<br>
<br>
resXY@tmXTMode = "Explicit"<br>
resXY@tmXUseBottom = False<br>
resXY@tmXTLabelsOn = True<br>
resXY@tmXTOn = True<br>
<br>
resXY@tmXTValues=(/ chanels_by_num /)<br>
<br>
and the for the resXY@tmXTLabels i assigned them to 616 values that<br>
range from 16 to 8078.<br>
<br>
then i get this error :<br>
<br>
warning:ExplicitComputeMajorTi<wbr>ckMarks: Maximum tickmarks (256) has been<br>
reached, tickmarks may appear in complete<br>
<br>
and my plot looks as all the labels are squeezed to the left on the top<br>
x axis.<br>
<br>
I attach my ncl code.<br>
<br>
Thank you very much, really need some help here<br>
<br>
Voula<br>
