Changing xy graph scale using combo box selection

Hello,
I have a xy graph with x scale set to 10k and y scale set to 6 by default.
I have a combo box which i use to select what the graph will display. For example in combo box i have 3 choices, A, B, C.
If i select A, xy scale is set to 10k and 6. If i select B, xy scale is set to 2.5k and 8, if i select C, xy scale is set to 4k and 10 respectively. Is there some functions that i can use to do this?
Thanks.
Solved!
Go to Solution.

Like this (attached)?
Of course, if the data actually follows these mins and maxes, you could just turn on auto scaling and it would do it automatically

How to view the records in datagrid using Combo Box Selection

hi friends,

If i click any one of the students name it will only show the Particular student record in datagrid with respective fields(student name,rollnumber,percentage);
how i will do this
please give any suggession or show snippet demo.
it will be more helpful to do this,
Thanks in advance
B.Venktesan.

Hi,
As your requirement , i think you will have to use selectedItem or selectedIndex property of combobox. And accordingly fetch data and provide it to dataprovider of datagrid.Following code can help you.

Using Combo box at the backend

Hi,
I am using combo box at the backend to filter rows to a particular destination.
The problem is the labels are going to populate at the runtime and the selection of item in combo box is also going to populate at the run time. I have an icon which inserts eg: country in a cell, then this cells is used by combo box as a item selection(label) to filter rows from source. But unfortunately the comb box is not selecting any value i.e no item is selected dynamically. But if i manually drill down it is working but the label is not changing dynamically based on the changes in label by icon.
For eg my data:
Country and profit populate at run time
Country          Profit
India               5000
Germany        4000
Now i have icon which selects country (hard coded in excel) upon clicking the mouse on it and inserts in A1 suppose the value hardcoded is "India". Now this A1 is used as a "selected item" for combo box. the source to combo box is the above country and profit which populates at run time.
Now when i execute the dashboard. The value is inserted in A1 after clicking the icon but it is not picked up by combo box as "item selected" and hence combo box does not filter any data.
Can any pls help.
Thank you. I will award full points for correct solution.

Hi Monammed,
The said functionality should work. Please check your logic one more time. Also, try using some spreadsheet components mapped to the cells in question and understand how the data is flowing during run-time. This will help you test things. Delete spreadsheets when you are done with identifying the issue.
Lets check the combo box mapping one more time : Map the source of the combo to the entire range; labels in the combo box ONLY to the country column in the source range(typically this may be the left most column in the range); selected item should be mapped to the cell that has the destination for the icon and the type for default selection may be dynamic. Well, if there is any hard-coding of values involved anywhere, do check the spellings and other trivial things.
Do let me know if this was helpful and if you need any more help.

Combo box selected index is not working.

Hi guys, I have a problem with changing the combo box selected index.
I load a list of phone types(such as "Home","Office",...) using Remote Object and assign it as a data provider for a combo box.What I need is to select a specific index in the combo but combo.selectedIndex statement doesn't work for the first time, I mean the combo changes its index only if I load the view again.
I checked different examples, solutions but none of them worked for me!! Can anyone here help me to figure out the problem?
Here is my Code:
<mx:Canvas creationComplete="init()"
             xmlns:mx="http://www.adobe.com/2006/mxml">
     <mx:ComboBox id="comboPhone0"
                prompt="Type"
                dataProvider="{phoneTypeList}"
                />
<mx:Script>
     <![CDATA[
[Bindable]
private var phoneTypeList:ArrayCollection;
private function init():void
     loadPhoneType();
private function loadPhoneType():void
     phoneTypeLoaderService.getPhoneType(); //phoneTypeLoaderService is a remote Object to load the phone types
private function handlephoneTypeLoadResult(ev:ResultEvent):void
     phoneTypeList=ev.result as ArrayCollection;
        comboPhone.selectedIndex = getComboSelectedIndex("HOME");
private function getComboSelectedIndex(phoneType:String):int
var index : int= -1;
var result : int= -1;
     for each (var pt:PhoneType in phoneTypeList)
          if (pt.type == phoneType)
                    result = index;
                    break;
          else{
               index++;
          return result;
     ]]>
     </mx:Script>
</mx:Canvas>

hi
I think in getComboSelectedIndex() method index should initialized to zero. If that does not work use after assigning the data from result event.
phoneTypeList.refresh();
Hope this helps

Dynamically change the contents of one combo box based on the other

Hi Forum,
I have a question which might have a possibly simple answer. Well anyway help me out since i could not find the simple answer.
I am building an application using Swing and binding with BC4J using JClient. My GUI has combo boxes, grids, editboxes. My requirement is that i should be able to dynamically change the contents of one combo box based on the selected item in trhe previous combo box. For example, when i choose a country in the "country combo box", the "states combo box" should show the list of the states of the selected country.
Now how do i do this using binding. If not, how do i write custom querirs in BC4J layer and return a resultset to the remote application so theat i can populate the dependent combo boxes.
I will appreciate if anyone can help me out in this regard.
Thank You
Sumit

there could be quite a few number of ways of solving this problem.
One way is through event handlers.
taking your example as a model when user selects a country you could fire an action with a flag set to ture. A method will return the states from the DB or your temporary files or what ever and then the true flag will be used in the states combo box rendering.
other way: javascript
this might be a bit clumsy as you will need the states information in a property file and you can get the info as the user selects a country.

Combo box select default value.

Hi,
I am using Combo box to display the status of the document.
my code is
oForm = SBO_Application.Forms.Item("I8_BGU_")
                        Dim oCombo1 As SAPbouiCOM.ComboBox
                        oForm.DataSources.UserDataSources.Add("ComboSrc5", SAPbouiCOM.BoDataType.dt_SHORT_TEXT, 1)
                        'oItem = oForm.Items.Item("21") ''for accessing the combo box item
                        oCombo1 = oForm.Items.Item("21").Specific
                        '' to bind the combo box item to defined user data source
                        oCombo1.DataBind.SetBound(True, "", "ComboSrc5")
                        ''giving some static values to combobox
                        oCombo1.ValidValues.Add("Open", "Open")
                        oCombo1.ValidValues.Add("Closed", "Closed")
                        oCombo1.ValidValues.Add("Extended", "Extended")
                        ' oCombo.Select("Open")

                        oCombo1.Select("Open")
In this code when it reaches last lineof line it is throwing error.
Object refertence not set to any instance..
some time it is throwing
error,,
" Unble to cast COM object sbouiCom.itemeventClas to Interface Type IItemevent. This application Cal is failed.
The same logic working form for another form..
Is there any modification needed.
Please.. get to me..
mahi.

Hi Mahendra,
In case of selecting a default value in a combo, it has 2 parameters to be passed. Its as below.
objCombo.Select(0, SAPbouiCOM.BoSearchKey.psk_Index)
Replace this with proper value (1st parameter). It will work.
I find that you have already used that line. So you can remove your last line.

Locating on a location on GMap using combo box using SDK

Hi All,
I have a requirement to locate a city on google map using combo box. I want name of cities to appear in combo box and on selecting a city, map should be able to locate that city. This combo box will be visible on map itself. Combo box can be a component of either Xcelsius or Flex Builder.
I think combo box dragged from Xcelsius component panel not able to communicate with google map which is embedded in form of swf through manage and packager.
So, I tried with Flex Builder combo box component, but not able to done it. I am not getting the flow how to communicate between combo box and google map.
I can locate a particular city giving a latitude and longitude through propertysheet.
Please, if anyone could help me out asap.

Change combo box selection dynamically?

I would like to have a combo box change its selection dynamically according to what is selected in another selector. As far as I can tell from reading the Help, this feature is available for List Boxes, List Views and List Builders only ("The Dynamic Selected Item functionality is available in list-based selectors") and based on the wording I assume that it is currently unavailable for other components. Is this true? If so I would like to formally request that other selectors - particularly combo boxes - be included.
The use case for me is this: After the user has already inputted information and digested some of the output, they eventually reach a section of the project that appears only under certain conditions. This area is about 800 pixels to the right of the original combo box in the inputs area, and so in order to quickly change that selection they would have to go look for the original selector, which could easily discourage them from browsing that particular selection. Hopefully this makes sense.
It would also be great to hear back that this kind of feature request can actually be made in this way. I've submitted a few similar requests in the past and did not see an acknowledgment, and so I am still unclear as to whether or not feature requests are even possible.
(Edit: I thought about creating duplicate overlapping instances of the combo boxes in question and, using dynamic visibility, control which appears according to the current selection. But this is only suitable for smaller lists).

Thanks, Alan. I am currently working on a similar solution. Seems to be the best for my situation, but it is far from elegant.

The Filter component requires that the underlying Excel data be structured in a pretty specific way. As far as I can tell, I would probably have to rip apart my XLS and redesign it in order to make use of that component. Perhaps in a future generation I'll give it a go, but I've already gone through too many redesigns this time around.

When i change the value of a combo box using a property node it displays the value not the item label

I am using a combo box as a select list for text serial commands. I have items like "engineering", "GUI", and "Scan" for the commands "MDE", "MDN", and MDS respectively which i have input as the corresponding value in the combo box. so for example the label "engineering" has the value "MDE" in the combo box items list. when the Vi starts it needs to read the current value MDE, MDN, or MDS and then i want it to display on the front panel the item text corresponding to that command value.
To do this i have tried to read the serial command, ie MDS and then wire that to a "value" property of a property node of the combo-box, but instead of displaying the corresponding item label, "Scan", it displays the value "MDS" on the front panel instead. i want the front panel to use the label text when choosing and displaying but the block diagram to use the serial commands. Can this be done with a combo box? I'm trying to use a combo box so i can keep it all text and avoid having to build a case statement to convert enums or rings from a numerical value to the text command.
The correct text value is wired to the value property and it does exist in the combo-box. I have unchecked "values match items" and selected to not allow undefined values.

Don't use the value property node. Use the Text.Text property node. When creating the property node, select Text, then in the next pop-up box, select Text.

Combo Box Selection to Change Selection in another Combo Box

I'm pretty familiar with excel and VBA, but when it comes to Adobe Acrobat, I am lost with Javascript.
I am creating a form.
My first field is a combo box named: Rent.booth
My second field is also a combo box named: County.booth
I need to know where and how I would implement a java command that states that if Rent.booth = Rent, then County.booth automatically = No.
If No is selected for Rent.booth, then allow the user to choose any of the 3 values.
Combo Box Options for Rent.booth:
Select One
Rent
No
Combo Box Options for County.booth:
Select One
Yes
No
Any leads would be appreciated. So far I've only seen the Combo Box to Text box solutions, nothing for Combo box to Combo Box.

You'll get the best help with Javascript in the Acrobat Scripting forum.

A text box should appear based on combo box selection in a jsp page.

Combo Box Selected Data

I have a combo box called class_cb, I am trying to use the
combo box in a maths formula.
I am trying to set that if the active selected combo box data
= 1 then a text area = given number, if data = 2 then ....
I can get flash to recognise the change i just can't seem to
get the statement
"if selected combo box data = 1 then text area = 5" to work,
the text area defaults to the first value and changing the
combo box item and pressing calculate doesn't change the
value of the text box.
Any help would be appreciated, thanks

Report error when using combo box and one text field is empty

I'm building an interactive pdf in adobe pro 9. My problem is the following: I have one text field where you can enter a numeric code and that is used to populate another text field when I choose an option on one combo box.For example: suppose I write the code 123 in the text field "A" and that the combo box has two options ("data" and "-"). When I select "-", another text field "B" is empty, while when I select "data" i populate the text field "B" using the code entered "A" with the text "data_123". In order to do this I use the standard javascript code in the Format>Custom tab of the combo-box.
My questions are:
- how can I prevent the pdf to proceed selecting an option in the combo box when the field "A" is empty?
- how can I update the field "B" every time that I change the text in "A"? I found that the text is "B" is updated only when I press the selection in the combo box.

You can set the combo box to read-only in the Validate event of the A field:
// Validate script for text field
getField("combo1").readonly = !event.value;
To update the value of B when A changes, you can expand the script above to something like:
// Validate script for text field
var f1 = getField("combo1");
var f2 = getField("B");
// If there is an entry in the A field...
if (event.value) {
    f1.readonly = false; // Make sure the combo box is activated
    f2.value = f1.value === "-" ? "" : "fa.value + event.value; // Update the value of field B
} else {
    f1.readonly = true; // Deactivate the combo box
    f2.value = f2.defaultValue; // Reset field B
You might also want to reset the combo box somewhere in there, but it's not clear to me when you would want to do that.

Invalid precision/scale on combo box

I am dragging a field over to a table view on a panel as a combo box. I go to the list binding editor to setup the data to choose from in the combo box. I am using the LOV mode to get the data from another table. Everything looks good when I test the form. The combobox shows the data from the table that i'm getting it from. The problem is when i try to change the data on the form. I'm am getting an error message stating invalid precision/scale. The field from the source LOV is named CustomerName, setup as Varchar2(30). The field in the Target attribute is named CustomerAssigned, setup as Varchar2(30). Is the problem somewhere else and this error message an erroneous message? Help!!

After much hair pulling, what I did was created a new View link of the table i used for the source, then named the field in new view link as the same as the target field and it worked. Let me see if I can explain.
Source: Customer_Master / Customer_Name
Target: Line1ProperziDtl / Customer_Assigned
The above gave me the error message. I then created a new view link from the Customer_Master:
Source: CustAssignedMaster / Customer_Assigned
Target: Line1ProperziDtl / Customer_Assigned.
This worked with no errors. Why would it matter what the field names are as long as the Datatype and Sizes are the same?

Help needed: triggering a combo box selection

I'm new to creating forms in Acrobat (Acrobat 9 on Mac). I'm trying to create a form for my department where a student selects a faculty name from a combo box, and once the value is selected, another field is filled with an int value (course section number).
Question: what is the correct trigger for executing the javascript for this? Mouse up seems to trigger too early and the others don't seem appropriate.
I think my rudimentary JavaScript knowledge can get me far enough to check the value and the use a switch/if to prefill the int value in the other field, so the correct trigger is my current issue.
Thanks in advance.

I found where it's supposed to be stored, but I'm having some issues with missing (). I'm using Acrobat X Pro for Windows Vista.
