Utilizing the components within the range set by paper.setStart() and paper.setFinish() in Raphaels

My question has two parts - the first and second part. Let's consider an example code that I am working on. I am creating a map of my country with regions, and I want to perform actions on the entire map such as scaling or translating (as seen in the commented line). Additionally, I also need to work with individual regions or only one region at a time. Since I am new to Raphaels and JavaScript, I am unsure about how to achieve this. Below is some pseudocode illustrating how I would approach it, but I know there is a better way to do it. Can someone guide me on how to proceed? Here is the code snippet:

 window.onload = function() {
      var p = Raphael("paper");
      p.rect(0,0,600,350);

      p.setStart();
        var region1 = p.path("M404 ...");//I wont write all path here, "..." = rest of the path
        var region2 = p.path("M173.5 ...");
        //... rest of regions
      var map = p.setFinish();
      //map.scale(...).translate(...);// ... means just something correct is inthere

  //I wanna do first for example something like this
   map.region1.attr({
     fill: "blue"
   });
  //how should I do it?
  //Then second I would do also something like this
   for (region in map) {
      region.attr({//something...});
   }
 };

Answer №1

For your task, I suggest focusing on these two key techniques...

set.forEach(function(e){
    //perform an action on each element here
})

set.transform('t100,100s2'); //apply translation and scaling

To get started, explore the documentation available at . This resource will provide valuable information to begin with. If you encounter any specific challenges, feel free to create a jsfiddle (you can include the Raphael library on the left) and share it for further assistance.
