DVT Graph - setting tooltip dynamically.

Hello,
How can I set tooltip for a graph in java class?
I know setting tooltip in ".jsp" but I need to set it in java class.
Thanks,
Mina

Hi Sumit,
It worked creating the graph programmatically using the code below.
Thanks for your help.

Bug in dvt:graph tag? Cannot set graphType attribute using EL expression

Dear all,
First thing sorry if this is not the correct forum, but I have a problem that is driving me crazy with ADF DVT tags in JDeveloper environment.
I'm working with DVT tags to display some graphs in my application. I need to decide at runtime the type of graph I'm going to render in my page, because the type of graph is stored in a database. Also, I use tabular data instead of Data controls, because I have to reuse POJO objects from an existing model tier.
I have seen that you can bind the graphType attribute of <dvt:graph to a backing bean property, as explained in : http://www.oracle.com/technology/products/jdev/11/how-tos/dvt_how_tos/adf_dvt_graph_howto.html. You can even change the type dynamically responding to user actions, ie : you can change for example from BARS to AREAS or whathever. So far so good, the problem is that I have tried the simplest example possible and it seems that I cannot bind the graphType attribute to a backing bean property using an EL expression.
In my example, the backing bean has a type property with fixed value AREA_VERT_ABS, but it renders as a BAR_VERT_CUST, that is to say, it completely ignores the binding for the graphType attribute, but the binding for the tabularData attribute works properly because it renders the dummy data provided. I have tried with other types of graphic and it always renders as BAR_VERT_CUST.
I'm working with JSF 1.2 + Facelets + JDeveloper 11.1.1.2.0 and the integrated weblogic server.
My page is a facelet page as follows :
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<f:view xmlns="http://www.w3.org/1999/xhtml"

<dvt:graph id="g1" graphType="#{graphBean.type}" tabularData="#{graphBean.tabularData}" >
</dvt:graph>
</af:form>
</af:document>
</f:view>
My backing bean :
public class GraphBean {
private String type = "AREA_VERT_ABS";
public GraphBean() { }
public String getType() {
return type;
public List getTabularData() { // here I return a hardcoded list that is properly displayed ///
Note : the sam page but changing #{graphBean.type}" by "AREA_VERT_ABS" renders properly :
<dvt:graph id="g1" graphType="AREA_VERT_ABS" tabularData="#{graphBean.tabularData}" >
</dvt:graph>
Any advice will be very much appreciated.
Thanks and regards,
Plan.

Hello,
Actually the setter is not needed because the tag only reads, but it does not update the backing bean.
Anyway for verification pourposes I have changed to the following version without results.
Anyone from Oracle could give me some light ?
public class GraphBean {
private String type = "AREA_VERT_ABS";
public GraphBean() {
public void setType(String type) {
this.type = type;
public String getType() {
return type;
}

Setting Graph View Usage dynamically

Hello all,
I have a Graph Table with 2 graphs (Pie and Bar) and I'm trying to set their View Usage dynamically with the code below but it's not working. There is no error message, it just simply doesn't return anything. We need to set it dynamically because we have different levels and VO's to the same graph page.
Is there anything else that should be done?
OAGraphTableBean graphTable = (OAGraphTableBean)webBean;
if(graphTable != null) {
graphTable.setViewUsageName("OperationHdrGraphVO1");

Eduardo

Advanced dvt:graph customisation

Hi,
I need to make the following changes on a dvt:graph ( graphType="PIE" ) but I don't see how I could do it.
1- Set the font for the Title, Subtitle, Footnote and legend elements
2- Avoid truncating the Subtitle when its too long
3- Set the space before and after the pie ( after the subtitle and before the legend )
4- Completely hide the label under the pie ( data label )
I know there is also a "advancedPropertiesXML" on the dvt:pieGraph but I can't find any example for that.
Is it possible to do that?
Thanks

Hi,
We are working on exposing the pie label as a child tag, but in your current build you will have to set it via the other properties XML or via Graph Java API.
Here as an example of binding the whole graph. this would be the code in your backing bean:
public UIGraph getMyGraph() {
if (m_graph == null) {
m_graph = new UIGraph();
CommonGraph graph = (CommonGraph)m_graph.getImageView();
// Customize the Pie label
String pieLabel = "<Graph version=\"11.1.1.0\"><PieLabel>" +
"<GraphFont size=\"16\" /></PieLabel></Graph>";
m_graph.setOtherProperties(pieLabel);
return m_graph;
In your jspx page:
<dvt graph ...
binding="#{MyBean.myGraph}"
</dvt:graph>
Or, you can bind only the otherProperties property in the backing bean.
Hope this helps

DVT graph not filling entire container width

Experts,
I have a DVT bar graph in my tabbed panel having "AFStretchWidth" set inside a panelHeader. But my graph is not stretching to fit the entire screen. I have also tried to set the "AFStretchWidth" in the graph but not productive.
eg: panelheader having
- panelTabbed styleclass set "AFStretchWidth" containing
- dvt styleclass set "AFStretchWidth"
Any ideas how to make the graph fill the entire container width ?
thnks

Make sure that Tab Panel (or parent of DVT Component) is stretched.
Set dynamicResize property value of DVT to DYNAMIC_SIZE.

How to change series/groups of a DVT graph at runtime?

With my scenario, I would like to bind a graph with a dynamic query. "Dynamic" means the query constructed at runtime. So I want to detrmine the series and groups of a DVT graph at runtime. I.e., I want to do this with Java programatically.
I read some articles and tutorials but have not found a topic on this. I think this should be a common requirement. Anyone can tell me how to do this? Thanks.

Are you using ADF BC and data binding or regular JSF binding?
For the first one you can try and create a VO with columns a,b and then at runtime change the VO definition similar to how it is done here:
http://blogs.oracle.com/shay/2010/10/adf_faces_dynamic_tags_-fora.html
(but keeping the synonyms for the columns constant).
For case B - you just need to change the collection data that you pass to the graph.

Check to see that your little one did not by accident get something (anything) in the headphone jack. If there is debris in there (and it doesn't take much) it will make your device think a set of headphones is jacked in and you won't be able to hear through speakerphone or handset.
While holding it with the jack down, blow across the jack and tap gently. It often will dislodge whatever is in there.

Can we set the dynamic data source when using getReportParameters() ?

Hello!
I have a report where one of its parameters refers to a list of values (LOVs). This list of values is an SQL Query type. When the data source used in the report is defined in the BI Publisher server, I'm able to get the report parameters using the getReportParameters() function in my application. However, if the data source is not defined the function throws an exception, which is understandable.
I decided to dynamically set the data source so that even if the data source used by the report is not defined in the BI Publisher server, it still will be able to get the LOVs for the parameter. I tried setting the JDBCDataSource of the dynamicDataSource for the ReportRequest object that I passed to the getReportParameters() function. Please see the sample code below:
reportRequest.dynamicDataSource = new BIP10.BIPDataSource();
reportRequest.dynamicDataSource.JDBCDataSource = new BIP10.JDBCDataSource();
setReportDataSource(reportRequest.dynamicDataSource.JDBCDataSource, connectstr, jdbc, dc); //function to set the values for JDBCDataSource object
reportParams = webrs.getReportParameters(reportRequest, uid, pwd); //call the getReportParameters
I was expecting this to work as this is what I did to dynamically set the data source before calling the runReport function. So, my question is -- can we set the dynamic data source when using getReportParameters() ? I tried this both in versions 10g and 11g. It does not seem to work on both versions.

Stephanie

report_id column of apex_application_page_ir_rpt can help us uniquely identify each saved report.
We can assign this report_id value to a page item and this page item can be put in the Report ID Item text box of the Advanced section of the Report Attributes page of the IR.
This should load the saved report identified by report_id and you can get rid of javascript

How can I cache dvt graph results?

Hello colleagues, I need some help regarding dvt graphs performance.
In our application we have big amount of data which the user can filter by adding grouping options, time ranges, etc. For the graph to be updated (the query to be re-executed), the user has to press a "Refresh" button each time he changes the query parameters.
Once the new results are displayed in the graph, the user can change the graph type by pressing either a pie, bar, line or table buttons. As a consequence of this, the query is re-executed and returns the same previous results. This obviously drops the performance of the application.
So, how we can manage to refresh the type of graph (for example from pie to bar) without re-executing the query. Note that the "Refresh" button should always re-execute the query even if the parameters were not changed.
I'll appreciate your help.
Regards,
Nicolas

And by the way how are you switching the graph type? Are you using an af:graph tag and switching just the type? Or are you rendering a complete new graph on your page?

1) You where given a working example in your last posting on this topic. Compare your code with the working code to see whats different and fix it.
2) The code you posted doesn't compile.
3) You didn't use the "Code Formatting Tags" when you posted your code so it not readable.
