dynamicUpdate: Boolean

Setting this to true (default) will update the StockChart dynamically while updating range using Slider. When set to false, StockChart will not update till you leave the mouse from Slider.

• It is recommended to set it to false while rendering large amount of data, because dynamically updating might affect performance.

var stockChart = new CanvasJS.StockChart("container",
{
 .
 .
 navigator: {
   .
   .
   dynamicUpdate: false,
   .
   .
 }
 .
 . 
});
stockChart.render();
