11g: How to show vertical gridlines and ticks only on full hours?

Question

Hi,
continuation of read-only preview thread dvt:graph How to show major ticks on X-axis only for full hours?
Katarina, I tried your suggestions with mixed success.
Here my starting code:
<dvt:graph binding="#{backing_lmrg0001.graph11}"
                                 id="graph11" imageFormat="FLASH"
                                 value="#{bindings.VwLmrgWerteGrafik.graphModel}"
                                 dynamicResize="DYNAMIC_SIZE"
                                 graphType="BAR_VERT_STACK2Y"
                                 inlineStyle="width:100%; height:50%;"
                                 noDataErrorText="#{bundle.NO_DATA_AVAILABLE_TEXT}"
                                 partialTriggers="::commandButtonCreateGraphic ::pollRefreshData"
                                 imageHeight="200"
                                 continuousTimeAxisInterval="CTAI_HOUR">
                        <dvt:referenceObjectSet>
                          <dvt:referenceObject lineValue="#{backing_lmrg0001.grenzwertAcetat}"
                                               index="0"
                                               displayedInLegend="true"
                                               text="#{bundle.GRAPH_THRESHOLD_ACETAT_LABEL}"
                                               series="0" color="#ff0000"
                                               lineWidth="2"
                                               location="RO_FRONT"/>
                        </dvt:referenceObjectSet>
                        <dvt:seriesSet defaultAssignedToY2="DY2_AUTO_ASSIGN">
                          <dvt:series color="#0052ff"
                                      markerType="MT_STEPPED_LINE" lineWidth="2"
                                      assignedToY2="false"/>
                          <dvt:series assignedToY2="true" lineWidth="10"
                                      markerType="MT_AREA" color="#e7e700"/>
                          <dvt:series color="#94f700" markerType="MT_AREA"
                                      lineWidth="10" assignedToY2="true"/>
                        </dvt:seriesSet>
                        <dvt:y2Axis majorTickStep="1.0"
                                    majorTickStepAutomatic="false"/>
                        <dvt:o1Axis/>
                        <dvt:o1MajorTick tickStyle="GS_GRID"
                                         lineColor="#00ff00"/>
                      </dvt:graph>The x-axis contains date values with a grid of 5 minutes over 12 hours.
The code above shows vertical gridline only at 00:00 o'clock.
The tick label displays every half hour (format HH24:MI) --> continuousTimeAxisInterval="CTAI_HOUR" seems to have no effect.
Then I changed timeAxisType from "TAT_DEFAULT" to "TAT_DEFAULT_STRICT".
Juhu, now vertical gridlines are displayed every half hour, but orientation of tick label changed from vertical to horicontal (format DD.MM.YYYY)!
--> Why????
Then I added following code:
<dvt:o1TickLabel automaticRotation="AR_NO_ROTATE"
                                         tickLabelSkipMode="TLS_MANUAL"
                                         tickLabelSkipCount="12"/>This changes the orientation of x-axis tick labels to horicontal AND tickLabelSkipCount has the correct effect ! (which is wrong when using timeAxisType=TAT_DEFAULT_STRICT)
Problem now is that format of tick labels is DD.MM.YYYY and not HH24:MI.
I tried following but with no success:
<dvt:timeAxisDateFormat dayFormat="NONE"
                                                monthFormat="NONE"
                                                quarterFormat="NONE"
                                                yearFormat="NONE"
                                                timeFormat="HOUR24_MINUTE"/>This keeps following questions open for me:
1) Why does tick label orientation and format changes if timeAxisType changes from "TAT_DEFAULT" to "TAT_DEFAULT_STRICT"?
2) How to change tick label format to HH24:MI, if timeAxisType=TAT_DEFAULT_STRICT?
3) continuousTimeAxisInterval="CTAI_HOUR" doesn't solve my problem to show tick labels only for full hours.
