我正試圖在angular2中繪製一張zing圖表。我的圖表就是這樣。 enter image description here調整x軸的最小值最大值以自動調整圖表

雖然我希望我的圖表看起來像我在下面提供的圖表,所以x軸的最小值和最大值會自動調整以適合圖表的區域和水平寬度。 enter image description here

我該如何去做這件事?我遵循這些鏈接,但無法獲得理想的結果。你能指出我哪裏錯了嗎? https://www.zingchart.com/docs/tutorials/chart-elements/configure-chart-scales/#scale-formatting 是我給繪製圖表如下選項:

this.charts = [{ 
      id : 'chart-1', 
      data : { 
       'type' : 'area', 
       'scaleX': { 
       'label': {'text': 'Price'} 
       }, 
       'scaleY': { 
       'label': {'text': 'Cumulative Volume'} 
       }, 
       'plotarea': { 
       'adjust-layout': true /* For automatic margin adjustment. */ 
       }, 
       'scale-x': { 
       'auto-fit': true, 
       'min-value': minValue, 
       'max-value': maxValue, 
       'decimals': 2 

       }, 
       'series': [ 
       { 'values': this.bidArray }, 
       { 'values': this.askArray } 
       ], 
      }, 
      height: 300, 
      width: 600 
     }]; 
    } 

編輯1: 比達雷askArray是數組的格式陣列。

您不需要將屬性auto-fit設置爲true。這適用於應用了縮放的圖表。

您不需要設置屬性min-valuemax-value以使x軸自動適應。它會默認執行此操作。

問題可能在於您沒有提供任何信息的圖表的一部分。你的數據如何繪製?什麼是數組值?數組陣列?

發佈完整的圖表JSON,我會給你演示工作。由於您的圖表是動態的,因此您可以通過右鍵單擊圖表來獲取渲染JSON,單擊查看源代碼選項,然後複製解析的JSON選項卡中的內容。

EDITED新的應答響應於第一評論BELOW:

陣列陣列不會自動適應上的scaleX圖形寬度。原因是你要求繪製比單維數組更具體的東西。所以你是正確的設置minValuemaxValue

主要問題是step的值。由於您定義的步驟不如minvaluemaxvalue中的值精確,因此您必須使其匹配相同的精度。例如,你把兩位小數,你的步驟設置爲step:.2,這只是一位小數的精度。將該精度更改爲兩個。 step:.01 || .02以獲得所需的結果,您正在尋找。

一個快速旁註。您有兩個scale-x對象。他們在內部合併,但這是危險的,因爲較低的將覆蓋第一個。如果你有一個大的JSON,這將變得更難調試。

非常感謝你爲我解決這個問題。最重要的一點是不要同時有兩個scaleX和scale-x對象,只有一個scale-x對象。 – codestruggle
