Animation function is working but graphic moves to different screen coordinates. Please suggest.

Krish,

   The issue you are having now is that you are setting the animation start and end values the way you were before and I added the "original" property to the animation which mean use the shapes original coords and add the end values to the start original (0,0).

Krish,

   You need to account for the height of the SVG in your transform:

transform: [{
  name: "translate",
  start: [sp1.x, (sp1.y - shape.bbox.b)],
  end: [sp1.x + 50, (sp1.y - shape.bbox.b)]
}]

Hi Robert,

Thanks for your quick response!

I have tried above code and observed when I pan on map and create point, graphic moves to different screen coordinates.

Please suggest how to achieve this.

Regards,

Krish

Krish,

   That is because you are not updating the points geometry to the new MAP coordinates after the animation of the points screen coordinates are done. Here is your code updated:

Hello Robert,

Thanks for your response.

I tried code suggested by you to move point from one coordinate to another as shown below. But animate is not shown on map. Please let me know where I'm doing wrong.

Krish,

   The issue you are having now is that you are setting the animation start and end values the way you were before and I added the "original" property to the animation which mean use the shapes original coords and add the end values to the start original (0,0).

There is no other way in 4.x currently. The ability to animate will be improved in future releases.
