Cathryn,
I think you just need to set tmXBValues and tmXBLabels in Explicit
Mode. If you don't give the values (& labels) I think the plot tick
mark mode reverts to Automatic.
http://ngwww.ucar.edu/ngdoc/ng/ref/hlu/obj/TickMark.res.html
*tmXTMode*
This enumerated resource of type NhlTTickMarkMode
<http://ngwww.ucar.edu/ngdoc/ng/ref/hlu/obj/TickMark.obj.html#NhlTTickMarkMode>
determines the method for specifying the spacing of the ticks and
the contents of the labels along the top X Axis. It has three
possible settings:
|Automatic|:
Based on the values of /tmXTDataLeftF/ and /tmXTDataRightF/,
*TickMark* chooses a 'nice' spacing between the major tick
marks, such that the number of major ticks does not exceed the
value of /tmXTMaxTicks/. Labels are generated based on the
current settings of /tmSciNoteCutoff/, /tmXTAutoPrecision/,
/tmXTPrecision/, and /tmXTFormat/.
|Manual|:
Starting with the value /tmXTTickStartF/, *TickMark* sets major
tick marks at intervals separated by a distance of
/tmXTTickSpacingF/ until /tmXTTickEndF/ is exceeded. Of these
tick marks, only those that fall between /tmXTDataLeftF/ and
/tmXTDataRightF/ may appear along the top X Axis. If
/tmXTTickStartF/ and /tmXTTickEndF/ are not set, *TickMark*
issues an informational message and sets /tmXTTickStartF/ to the
minimum of /tmXTDataLeftF/ and /tmXTDataRightF/, and it sets
/tmXTTickEndF/ to the maximum of /tmXTDataLeftF/ and
/tmXTDataRightF/. If /tmXTTickSpacingF/ is not set, *TickMark*
issues a warning message and /tmXTMode/ reverts to |Automatic|
mode. Labels are generated based on the current settings of
/tmXTTickSpacingF/, /tmSciNoteCutoff/, /tmXTAutoPrecision/,
/tmXTPrecision/, and /tmXTFormat/.
|Explicit|:
*TickMark* uses the array resource /tmXTValues/ to determine the
coordinate positions of the tick marks. Of these tick marks,
only those that fall between /tmXTDataLeftF/ and
/tmXTDataRightF/ may appear along the top X Axis. If
/tmXTValues/ is not set, *TickMark* issues a warning message and
/tmXTMode/ reverts to |Automatic| mode. The corresponding
element of the string array resource /tmXTLabels/ determines the
label used for each tick specified by /tmXTValues/. If
/tmXTLabels/ is not set, *TickMark* issues a warning and outputs
no labels for the top X Axis. You may optionally also set the
array resource /tmXTMinorValues/ to specify the locations of
minor ticks along the axis.
This resource may be intercepted or disabled by:
*tmXBValues*
When /tmXBMode/ is set to |Explicit|, this resource specifies an
array of data locations at which major tick marks will be drawn. The
values must increase or decrease monotonically. If you do not set
/tmXBValues/ when in |Explicit| mode, *TickMark* issues a warning
and /tmXBMode/ reverts to |Automatic| mode.
When /tmXBMode/ is set to |Automatic| or |Manual|, you can retrieve
this resource to determine the values that *TickMark* has chosen for
the bottom X Axis major tick locations. Attempts to set the
resource, however, are ignored.
This resource may be intercepted or disabled by:
* *MapPlot*
<http://ngwww.ucar.edu/ngdoc/ng/ref/hlu/obj/MapPlot.obj.html#TickMark.res>
Default: NULL**
*tmXBLabels*
When /tmXBMode/ is set to |Explicit|, this resource specifies an
array of strings that correspond to the values in /tmXBValues/. Each
element of this resource is placed under the corresponding tick
location in /tmXBValues/. If a string array element is set to NULL,
no label will appear at the corresponding tick mark location. If you
do not set /tmXBLabels/ when in |Explicit| mode, *TickMark* issues a
warning and outputs no labels for the bottom X Axis.
When /tmXBMode/ is set to |Automatic| or |Manual|, you can retrieve
this resource to determine the strings that *TickMark* has chosen as
labels for the bottom X Axis major ticks marks. Attempts to set the
resource, however, are ignored.
This resource may be intercepted or disabled by:
* *MapPlot*
