ReportMap Release 1.4

Release 1.4 of the JK64 Report Google Map R1 has been released with a number of bug fixes and enhancements. You can review the changes here: https://github.com/jeffreykemp/jk64-plugin-reportmap/releases/tag/v1.4. The most important enhancement is a new Dynamic Action plugin that is included as a recommended companion to the map plugin.

The Dynamic Action plugin, called JK64 Report Google Map R1 Action, allows you to implement any of a range of custom behaviours on your map region. If installed, you can make the map respond to user behaviour or other events without needing to resort to writing your own custom JavaScript.

You can add a dynamic action to modify a variety of options and attributes of the map, execute searches, pan and zoom, load features via geoJson, and more – and these can be based on the value of items on your page, or via JavaScript expressions that you specify.

For example, on the demo Plugin Options, the user can change the map type:

This is implemented as a radio item with a dynamic action on the Change event:

The dynamic action has the following attributes:

Note that in this case, it sets an Option – Map Type, based on the triggering element (the P28_MAP_TYPE item). The Affected Elements is required, and must refer to the map region that we want to change.

Notice anything missing? That’s right – No Code needed!

The plugin makes it easy to customise which of the default Google Map controls (buttons, etc.) are shown to the user:

  • Full Screen control
  • Map Type control
  • Rotate control
  • Scale control
  • Street View Pegman control
  • Zoom control

Other options that can be set include:

  • Clickable Icons
  • Disable default UI
  • Gesture Handling
  • Heading
  • Keyboard shortcuts
  • Map Type
  • Maximum Zoom level
  • Minimum Zoom level
  • Restrict search to Country
  • Styles
  • Tilt
  • Zoom level

In addition, the plugin allows you to restrict the map to a set of bounds, via the Restrict to Bounds or Restrict to Bounds Strict Mode actions.

You can browse all the possible actions in the WIKI: https://github.com/jeffreykemp/jk64-plugin-reportmap/wiki/DA-Plugin-Attributes-Reference


Another enhancement included in this release is explicit support for the Table / View data source. This is simple to use, although not quite as flexible as the SQL Query option. Your table or view must include columns with the correct column names expected by the selected Visualisation – for example, if your Visualisation is Pins, the table or view must have columns named lat, lng, name and id. Click the Help tab on Table Name for more details, or review the WIKI (https://github.com/jeffreykemp/jk64-plugin-reportmap/wiki/SQL-Query-Examples).


NOTE: the plugin supports APEX 18.2 and later. It is no longer planned to include backports for older versions of APEX.


A big thanks to many APEX developers around the world who have installed and used the map plugin over the years. Your suggestions, questions and bug reports have contributed a great deal to improving the plugin.

  1. Hi Jeffrey,

    First, I would like to say thank you very much for your contribution to the APEX community.

    I am trying to customize a marker using your example. I am running into a couple of issues.
    The first one is to customize the color of the icons based on a column with values (0 to 100). I am not that good at JS but here is my hacked code for it which is based on you example code. It just defaults to the last else statement. maybe it my JS code. The other issue is around scale. I wanted to use a dynamic scale based on a column value and tried to use your log scale, but it doesn’t seem to work for very big numbers.

    this.options.markerFormatFn = function(marker) {
    
        var population = marker.data.attr01;
        var srate =     marker.data.attr02;
    
        // icon can be a Symbol
        if (srate > 95) {
     
         marker.icon = {
          path          : google.maps.SymbolPath.CIRCLE,
          fillColor     : "green",
          fillOpacity   : 0.6,
          strokeColor   : "white",
          strokeOpacity : 1,
          strokeWeight  : 0.5,
          scale         : population
        };
        
    } else if (srate < 90) {
     marker.icon = {
        path          : google.maps.SymbolPath.CIRCLE,
          fillColor     : "yellow",
          fillOpacity   : 0.6,
          strokeColor   : "white",
          strokeOpacity : 1,
          strokeWeight  : 0.5,
          scale         : population 
        };
    
    } else {
    marker.icon = {
          path          : google.maps.SymbolPath.CIRCLE,
          fillColor     : "red",
          fillOpacity   : 0.6,
          strokeColor   : "white",
          strokeOpacity : 1,
          strokeWeight  : 0.5,
          scale         : population
        };
    }
    }
    

    Thanks again.

    • Hi Abraham,

      You may find you will need to diagnose your code – one way is to add some debug logging so you can see exactly what values are being used.

      e.g.

      this.options.markerFormatFn = function(marker) {
          var population = marker.data.attr01;
          var srate = marker.data.attr02;
          apex.debug("population", population, "srate", srate);
          ...
      

      Run the page, and see what values are being evaluated at runtime in your browser console.

  2. Hi Jeffrey,

    Thanks for the debug tip. The data was showing up as undefined for the two variables because I didn’t have the right order of columns in the SQL query. Now everything works fine. Thanks again for your amazing plugin.
    I don’t see a donate link on your web page. I do want to buy you a coffee :).

    Thanks,
    Abe

  3. Hi Jeff,

    I am using one of your code for “Sync with Report” to display map in my application. Your code refer to map data loaded through INITDATA in the application process which is a static data set. How do I load the map data directly from JK64DEMO_COUNTIES table instead.
    Please assist, your assistance with matter is very appreciative.

    Thanks,
    Thay

    • Hi Thay,

      You can base the report on a SQL query that retrieves data from any table you like. Change the SQL Query attribute on the plugin region to refer to the table of your choosing.

      Jeff

  4. Jeff,
    It is working now after replace the query to retrieve data from jk64demo_countries_vw. I was trying to associate my query to populate data into the sample MAP collection that was loaded in the application process. Your technical tip save me lot times. Your plug-in is amazing which provide lot of features that are impossible for people like me to make it happen. Your contribution and your effort make other people life easier.

    Thanks for a quick response
    Thay Ly
