Answer 1

Der Grund ist, zwei in den xAxis.categories verwendet Et-Zeichen.

"categories": [ 
    "Momentum & Stability", 
    ... 
    "Service & Support" 
], 

ändern Et-Zeichen zu %26

"categories": [ 
      "Overall", 
      "Vision/Strategy", 
      "Momentum %26 Stability", 
      "Innovation", 
      "Product Portfolio", 
      "Go-to-Market", 
      "Service %26 Support" 
     ], 

einen Rückruf schaffen, die Et-Zeichen codiert (auf dem Server Rückruf aufgerufen wird):

function callback() { 
     const categories = this.xAxis[0].categories.map(decodeURIComponent) 
     this.xAxis[0].setCategories(categories) 
    } 

den Rückruf Datenzeichen anhängen:

dataString = encodeURI('async=true&options='+optionsStr+'&type=jpeg&width=400&callback=' + callback.toString());
