範例：在繪圖中使用值域變數
繪製函數時使用值域變數，可控制繪製點數及繪製函數的範圍。
1.
定義值域變數。
<region id="ID0E15SMB" top="144" left="24" height="21.2" width="51.0866666666667" xml:lang="zh_TW" xmlns="http://schemas.mathsoft.com/worksheet50"> <math xml:lang="zh_TW"> <define xml:lang="zh_TW" xmlns="http://schemas.mathsoft.com/math50"> <id xml:lang="zh_TW" label="Variable">i</id> <range xml:lang="zh_TW"> <real xml:lang="zh_TW">0</real> <id xml:lang="zh_TW">π</id> </range> </define> <resultFormat xml:lang="zh_TW"> <decimal precision="3" show-trailing-zeros="false" radix="dec" imaginary-value="i" xml:lang="zh_TW" /> <matrix size="12,12" offset="0,0" xml:lang="zh_TW" /> </resultFormat> </math> </region>
2.
在參數繪圖中使用值域變數作為自變數。從
「符號」
清單加入交叉符號，以指出繪製點的位置。
