In column Chart when Y values are grater than y linear axis maximum it doesnt show the Bar

Hi Guys,
In column Chart when Y values are grater than y linear axis maximum it doesnt show the Bar.But i want show the bar upto the max limit of y linear axis without changing the max limit.
Consider following example:
Y values are 80 90 200 300
and following are the output :
Left:When i am not setting maximum property of linear axis.
Right :When i am setting maximum property of linear axis to 200.
In right 4th bar is not visible bcoz value for that bar is 300 which is excedding maxium.But i want the 4th bar to appear same as 3rd bar.
How i can do this?
Thanks in advance.

Are you going to show the bar going past the maximum value?
If not, then you should change the Y value when entered into the array to the maximum value allowed. i.e.
if(itemYValue > maxAllowedValue) {
itemYValue = maxAllowedValue;
Where maxAllowedValue is a variable you set on the application to control the maximum value for the chart.
This is assuming that you are loading the values into an Array before updating the chart dataprovider with that array.

Tracking the visible property of a movie clip

Hello,
I am trying to track the visible property of a movie clip as
I need to perform a function when visible = true and another when
visible =false
I have tried to use a listener object but I can’t get
it to work. Can you attach a listener object to listen for the
visible property?
I have also tried an IF statement inside the move clip but
this only knows the state of the ._visible when it first runs.
I have got it to work with an onEnterFrame function on a
movie clip inside the one I want to know the property of but I
don’t like using the onEnterFrame as it uses a lot or
processor speed
Is there an easy way to track the visible property of a
movieclip???
Thanks
Sam.

> thanks for the help but the watch() method doesn't work
for getter/setter
> properties. is ._visible a getter/setter property?
I was afraid of that. Yes, _visible is a getter/setter, most
properties are. Basically watch() only works on read-only
properties and custom variables, which is a shame.
So I don't know of any more elegant way than constantly
checking to see if the value changed. Centralize it and maybe
package it in a nice class and you might feel a little better about
it...

How to increment array that contains two clusters whose visibility is controlled by a visible property node and selected by a radio button.

I am trying to use a property node: visible in order to enable or disable one of two clusters. These clusters are in a larger cluster and this larger cluster is in an array. The two clusters are controlled by a radio button (one labeled transistor and the other diode). When diode is selected, the corresponding diode parameters cluster should be visible and when transistor is selected, the corresponding transistor parameters cluster should be visible. In the mean time, the cluster of the device that is not selected should not be visible. There are at least 45 elements in the array (but not more than 45). Data is entered into each cluster (diode or transistor data) for each element in the array via the increment/decrement. The problem is when you select the first radio button (transistor) and enter data, when you increment the array for a new device selection, since a visible property node was used on the cluster, a loop is created where a new cluster is trying to be shown, but the old cluster is also trying to be shown (because it is the one referenced by the property node. How do I get rid of this loop and still be able to increment the array and keep my data intact for future use? Attached is the vi

You could try something like this. However, if you know how to use an xcontrol, that would be a better way to implement the above functionality so that these UI characteristics are not a part of your main VI. The problem with the above VI is that you're looping every 100 ms just to update your UI.
Also, try using the "disabled" property node, instead of the "visible" one. That way, the user will still see the options he has but they will be grayed out.

I'm looking for some help connecting linksys IP Cameras to my home network to monitor my property when I'm travelling. I used to do this with linksys WAPS, but since I've discarded all my old linksys networking and standardized on airport, I can't get these things working. I know that I have to identify my camera through the DHCP table and set up port forwarding and there is the problem.
My network consists of 4 base stations set up in a roaming network - same network name and passwords. I need to do it this way so I don't have to switch network when I move from one side of the house to the other, go to the cabana, or my shop in the barn. The network works pretty well since I went to a roaming set up. Good performance, yata, yata, yata.
However, the roaming network requires the AEBS's to be set up in bridge mode, rather than sharing an ip address. When the AEBS is set to bridge mode, you don't see a DCHP table or have the ability to identify your IP Cam through the AEBS - and hence, no port forwarding.
I am able to identify and set up my Linksys IP Cam by locating the ip address on my FIOS router, even though, it's plugged into an AEBS. I set it up, see the video, remove the ethernet cable from the IP Cam, restart - and I can't get to it from an AEBS. In researching this, it appears, I should be setting up the AEBS to "share an IP Address", going to the DHCP table and identifying the camera's IP address and setting up port forwarding. However, you don't see any of the DHCP or port forwarding options in Airport Network Utility when configuring in bridge mode.
I'm hoping I'm missing something here and that the solution isn't to set it up at the FIOS router level, but I'm beginning to think that's my only hope. What concerns me there is that I should be able to see the IP cam on the network without port forwarding since I'm not coming from outside, and I can't even do this unless it's connected hard wire.
I'd appreciate any insight into this that anyone might have. I've hit the wall with what I know.
Thanks.

In a roaming network, your "main" router is the device that would require port mapping/forwarding to be configured in order to access the IP camera from the Internet. This router is also the one that would be provide the private IP address for the camera which you will want to be a static one.
So as you described your network, the IP cameras should be getting an IP address or you assigned it a static one and this is the address that you would enter in the Private IP address (or equivalent depending on the router used) field when setting up port mapping.
If you are not able to access this camera from the local network, then this should be troubleshot first.

Af:column visible property

Hi,
I am using JDeveloper 11.1.1.4 and ADF-BC in my application.
I want to pragmatically control the visible property of the af:column inside the table.
I have the following code for af:column.
<af:column sortable="false" headerText="Impact Cat New" id="c7" visible="#{row.bindings.Selected.inputValue}">
</af:column>
Initially, the value of 'Selected' will be false when the table is first displayed and hence it should NOT be displayed.
In the table selection listener,I set the property 'Selected' to true for the selected row and refresh the table[AdfFacesContext.getCurrentInstance().addPartialTarget(tblEmp)].
But Even after refresh the table is never showing the column for which visible is set as true.
The table is inside a panelCollection.
Please advice.
Regards,
Praveen

This won't work, as the column is the container for all rows and the row attribute is only available when the table rows arr stamped. I don't understand your use case. You want to show a column if one row gets selected? Sounds odd to me.
If you really want to do this, you have to set an attribute outside the table and use the selection listener to switch this attrbute. Then use the new attribute in the columns visible property.

Issues with less than and grater than condition in prompts in OBIEE 11g,

Hi all,
i am facing the prombles with less than grater than conditions in OBIEE 11g.
i created two date prompts with presentation variables datefrom and dateto
and i used these prompts in fileters like this using grater than and less than symbol.
filters are as below:
lastupdated date is grater than or equal to @{datefrom}{1/1/1950}
lastupdated date is less than or equal to @{dateto){1/1/1950}
and created two prompts
creation datefrom >=
creation dateto<=
when i passing the dates 05/12/2004 and 05/12/2005 in prompts after clicking the apply button in OBIEE 11g it feches all the records but i need records between these dates. and one more thing is after clicking apply button the two date fields getting the same date..
am i do any thing wrong in the above ???
please let me know friends..
waiting for ur replyyyyyy..
Thanks

Hi,
Create date prompts with operator as = not >= (or) <= as you need to save that value in presentation variable and you are filtering report using those variable filters.

Change visible property of iView assigned to page

Hello Mittal,
As per my understanding you want a way to dynamically edit the property of the PCD objetcs using PDK. SAP provides an API for the same puspose. Please refer to this link for more details

Visible Property of lable in Webdynpro

Hi all,
I have a lable and a inputfield which are hide. I want that when a select something in my dropdownbykey, this two objects get visible.
How can i do that?
Regards,
Nirali

Hi,
Please look this code
1.Create one Droupdownkey UI element in your firstView (Droupdown by key is bind to the one value attribute i.e MonthName)along this u can take 2 lable. For 2 lables you can set Visibility (com.sap.ide.webdynpro.uielementdefinitions.Visibility) property.
2. in wdinit() method you can write this code
ISimpleTypeModifiable myType=wdThis.wdGetAPI().getContext().getModifiableTypeOf("MonthName");
IModifiableSimpleValueSet values =myType.getSVServices().getModifiableSimpleValueSet();
values.put("Vijay","Vijay");
values.put("Kalluri","Kalluri");
wdContext.currentContextElement().setMonthName("Vijay");
wdContext.currentContextElement().setKalluri(WDVisibility.NONE);
wdContext.currentContextElement().setVijay(WDVisibility.NONE);
3.in Droupdownby key having OnSelect event in that place you can create on method. Under method you can write this code.
String firstName = wdContext.currentContextElement().getMonthName();
wdComponentAPI.getMessageManager().reportSuccess("First Name:"+firstName);
String lastName = wdContext.currentContextElement().getMonthName();
wdComponentAPI.getMessageManager().reportSuccess("Last Name:"+lastName);
if(firstName.equalsIgnoreCase("Vijay"))
wdContext.currentContextElement().setKalluri(WDVisibility.VISIBLE);
wdContext.currentContextElement().setVijay(WDVisibility.NONE);
else
wdContext.currentContextElement().setVijay(WDVisibility.VISIBLE);
wdContext.currentContextElement().setKalluri(WDVisibility.NONE);
Hope this helps u.
Best Regards

Help me on this..
Thanks,

Disabling the visbile property:
<af:inputText autoSubmit="true" id="it6" label="Table Attr"> </af:inputText>
<af:inputText partialTriggers="it6" visible="#{bindings.AphdBe.inputValue eq null? 'false' : 'true'} " id="it2" label="Trans Attr"> </af:inputText>like this you should h'd.
normally we use transiet term in vo's while coming to part ui.
it will consider as attribute. no thing difference bwtn those attribute as timo says.

Instead of using a jsplink you should use an af:goLink which is the adf equivalent and has all the needed properties.

JPEG image of a chart created while visible property is false has no plots shown

Hi
I have a chart which I control the visible property while it is plotting data. This works fine until I want to create a jpeg image of the chart when the visible propert is fasle and all I get is a chart without any plots.
Any way around this?
Thanks in advance

Being a newbie my and 1 week into LabView still getting to knoiw the ins and outs of the thing.
Well to ellaborate:
I have a chart which needs to be only visible when the user presses a 'view' button. When pressed this changes the visible property to true and the chart is displayed with the correct plots. Problem is theat when the user clicks a 'stop' button I save the chart to a jpeg (the user does not want to see the chart at this point) . This does work when the chart is visible all the time and out of view. The only crude way I have managed to get it to work so far is by changing to screen position of the chart and making in visible when the stop is pressed and moving it to the visible screen when view is pressed. See my crude solution attached:

Cfform Flash Datagridcolumn .visible property

Hey everyone,
I have a datagrid, and need to dynamically hide and show columns. My reading says the .visible property of a column should be able to do this. It does not work. Further reading indicates that I need a patch to fix this issue. However, the patch is for Flex and Flex builder. We do not have either of those projects, we just using Cold Fusion 8. We do not have Flex, or Flash installed. So how can I install this patch, or otherwise resolve this issue? And yes I did do a search on this topic (there were many results) but I could not find a straight forward answer on how to install this patch when you are not using either of the standalone Flex products. Thank you.

Install Flex 2.0.1 SDK and then ! a hotfix

Should help.

Non-Script Way of Setting Visible Property

Why hello there!
I am looking to set the "visible" property of a movie clip in
the Flash CS3 designer, as opposed to using AS3.
In my movie, I set a movieclip to invisible in code
immediately. However, I sometimes see the artefact of the image for
a split-second on running the swf in my browser. I would therefore
like to set the property in the designer.
I am guessing that there is not a way of doing it. Are there
any suggestions?
I'm now considering setting the alpha value to 0 in designer,
and then setting the alpha value to 1 in code when I need to be
able to see the mc.
Raffi.

Hey kglad,
I appreciate the prompt response. Sorry I wasn't clear enough
in my initial message.
I am simply looking to be able to set, say, a rectangle
primitive to invisible without having to set in the code. At the
moment, I am setting the visible property to false in the first
frame in the code. However, as a result, I sometimes (not
frequently) see artefacting when I run my movie. The rectangle very
momentarily appears before disappearing.
