Creating a Cool Dashboard in APEX

By
In my current project I have to create a dashboards that reflects the actual (and historical) situation in a factory. At first I tried something like the dashboards Anychart provides on it's site, like this. It is possible to create that kind of stuff in APEX, but then you have to generate all the XML data by yourself. And the fastest way to do something is...don't do it at all.

So, since the subregion-feature of APEX 4, you can achieve the same results by only tweaking the Chart XML itself a "little". And now I have something like this:
Kinda cool huh? I also created an example on apex.oracle.com (refreshes every 3 seconds with random data).

Hi Roel,

Linear gauge charts are not one of our supported and licensed chart types within Oracle Application Express. Only those chart types exposed via our Create wizards are supported.

What is the "small" tweak to the XML that you need to make? Care to share?

@Buzz: See the (changed) example. You can see the customized (non formatted) Chart XML using the little icons in the report on the right hand side.

@Hilary: "Not licensed" = "illegal"? That's strange, because I only used the default/standard APEX Features. Also your "support clause" surprises me...so Custom Chart XML isn't supported at all??? (I guess that's not what you mean, but pls clarify).

Hi Roel,

Our charts license allows Oracle APEX customers to create the chart types that we expose via our Create wizards i.e.

* Column (2D,3D,Stacked,Stacked %,Range)
* Horizontal (2D,3D,Stacked,Stacked %,Range)
* Pie & Doughnut
* ScatterMarker
* Line
* Dial & Dial % Gauges
* Candlestick
* Project & Resource Gantts

Linear gauge charts are not one of our licensed chart types, and are not exposed via our Create wizards. Therefore, unless you obtain a separate license from AnyChart, you are not licensed to use that chart type in Oracle Application Express. There tends to be some confusion around this area, but hopefully this will help to clarify things.

Regards,
Hilary

How do you create the ability to have chart data change like this?
5:26 pm

@Wayne : The query for every chart is something like :

select trunc(dbms_random.value(50,100)),100
from dual

and the charts refresh is set to every 3 seconds.

Fix Interactive Report headers issue when using a Region Display Selector

By
When you have multiple Interactive Reports (IR) on your page and use a Region Display Selector to mimic tabs, you might notice some weird behaviour in the IR headings if you switch tabs. The headings are not positioned correctly and you get an extra empty row under the headings. It just looks weird and ugly. But if you resize your browser window, it all looks fine again (until you switch to another tab..) So can we fix this by creating a Dynamic Action that mimics that "browser window resize" event? Yes we can! Create a Dynamic Action that fires on Click of the jQuery selector li.apex-rds-item a . That should fire a JavaScript snippet :  apex.event.trigger(this.triggeringElement, "apexwindowresized"); So now a click on a tab not only switches from one IR to another but also fires that event that will "autofix" the IR headers. A simple solution for an annoying problem. This applies to APEX 5.0, I assume it will be solved in 5.1.

How to create neatly formatted Excel documents using PL/SQL?

By
If there is a requirement to produce output from an application into Excel, you would probably create a CSV (Comma Separated File) with the data and start Excel to show the data - at least that's what I did...until now. The drawback of this solution is that you could only produce data and no nice layout. But Excel is also capable of opening HTML-files and using this you could create Excel files with data and magnificent layout! Let me give an example: 1. Create a procedure to show the data in formatted in an HTML table. CREATE OR REPLACE PROCEDURE display_emp_list IS v_emp_count NUMBER(5); v_empno NUMBER(8); v_ename VARCHAR2(50); v_job emp.job%TYPE; v_sal emp.sal%TYPE; v_bg_color VARCHAR2(10) := ''; CURSOR c_emp IS SELECT empno, initcap(ename), job, sal FROM emp ORDER BY ename; BEGIN SELECT COUNT(*) INTO v_emp_count FROM emp; owa_util.mime_header('application/ms-excel', FALSE); htp.p('Content...

Refresh selected row(s) in an Interactive Grid

By
In my previous post I blogged about pushing changed rows from the dabatase into an Interactive Grid . The use case I'll cover right here is probably more common - and therefore more useful! Until we had the IG, we showed the data in a report (Interactive or Classic). Changes to the data where made by popping up a form page, making changes, saving and refreshing the report upon closing the dialog. Or by clicking an icon / button / link in your report that makes some changes to the data (like changing a status) and ... refresh the report.  That all works fine, but the downsides are: The whole dataset is returned from the server to the client - again and again. And if your pagination size is large, that does lead to more and more network traffic, more interpretation by the browser and more waiting time for the end user. The "current record" might be out of focus after the refresh, especially by larger pagination sizes, as the first rows will be shown. Or (even wors...
