width: number

Sets the width of Range Selector in pixels.

Default: Automatically calculated based on StockChart width.
Examples: 400, 800, …
Note
  • We suggest not to set width/height property unless it is really required. When you don’t set width/height, CanvasJS automatically takes the size of range selector proportionate to StockChart. This helps you create responsive charts which adapts to varying screen sizes. 
var stockChart = new CanvasJS.StockChart("container",
{
 .
 .
 rangeSelector: {
   width: 400,
   .
   .
},
 .
 .
});
stockChart.render();
