Resizing the array of point graphics on the graphics layer does not reflect on the map view while zooming in or out when accessing the graphics.

Solution de contournement

To change Graphic.symbol at runtime, do one of the following:

• Clone the symbol and change its properties.
• Assign a new symbol.

The following code works. There is no need to remove and add graphics from GraphicsLayer to change graphic symbols. Use the layer.graphics.getItemAt() method to get the graphic instead of layer.graphics.items. 

var gp0 = layer.graphics.getItemAt(0);

var gp1 = layer.graphics.getItemAt(1);

var gp2 = layer.graphics.getItemAt(2);

const symbol0 = gp0.symbol.clone();

symbol0.size = 10 * rate;

gp0.symbol = symbol0;

gp1.symbol = symbol0;

gp2.symbol = symbol0;
