折線圖和面積圖標簽管理
通過標簽管理你可以調整折線圖和面積圖的畫布填充以適應長標簽。這保證了第一個和最后一個X軸標簽渲染到畫布外面以及標簽之間不會彼此重疊。
圖表會自動調整畫布的左右邊距來適應長標簽。2D折線圖的畫布填充標簽管理如下圖所示：
配置了canvasPadding屬性的2D面積圖如下圖所示：
下表是用于設置圖表畫布填充所需的屬性：
| 屬性名稱 |
描述 |
| canvasPadding |
用于設置畫布邊框和第一個數據點（或最后一個數據點）之間的間距。為0表示第一個和最后一個數據錨點將在畫布邊框上。 |
設置折線圖canvasPadding屬性的數據結構如下：
JSON:
{
"chart": {
"caption": "Quarterly Revenue",
"subCaption": "Last year",
"xAxisName": "Quarter",
"yAxisName": "Amount (In USD)",
"numberPrefix": "$",
"theme": "fint"
},
"data": [
{
"label": "First Quarter",
"value": "420000"
},
{
"label": "Second Quarter",
"value": "810000"
},
{
"label": "Third Quarter",
"value": "720000"
},
{
"label": "Fourth Quarter",
"value": "550000"
}
]
XML:
<chart caption="Quarterly Revenue" subcaption="Last year" xaxisname="Quarter" yaxisname="Amount (In USD)" numberprefix="$" theme="fint">
< set label="First Quarter" value="420000" />
< set label="Second Quarter" value="810000" />
< set label="Third Quarter" value="720000" />
< set label="Fourth Quarter" value="550000" />
</chart>
高級的X軸標簽管理可以實現：
- 所有X軸標簽必需與對應的列或點居中對齊
- X軸標簽間不能重疊
- X軸標簽不能與其它圖表對象如圖例或X軸名稱重疊
- 長標簽不能超出圖表范圍
- 優化長標簽的截斷，在末尾用省略號
高級的標簽管理不適用于Bar、Pie、Doughnut、Marimekko、Zoom Line和Multi-series Combination 3D圖表。
自定義數據標簽屬性
你可以自定義數據標簽的屬性，如：字體、邊框、背景、透明度。
字體屬性
2D柱狀圖自定義數據標簽字體、字體顏色、字體大小效果圖如下：
下表是用于自定義數據標簽字體所需屬性：

| labelFontColor |

| labelFontSize |
用于設置數據標簽字體的大小，從0到72。 |
| labelFontBold |
設置為1加粗數據標簽字體。 |
| labelFontItalic |
為1將數據標簽字體設置為斜體。 |
| labelAlpha |
用于設置數據標簽文本、背景、邊框的透明度，取值從0（透明）到100（不透明）。 |
