自定义图表构建器：圆圈与坐标不对齐

各位，

我尝试通过自定义图形在图形生成器中绘制一个圆，

可以看到，圆圈与数据点并不对齐。

如何才能做得更好，使圆圈在画布上的位置与数据点的位置完全一致？

为什么对y似乎可以，而对x却不行？还有其他方法可以实现吗？

谢谢，并致以最诚挚的问候，格奥尔格

回复：自定义图表生成器：圆圈与坐标不对齐

如何画圆？在大约四分之三处讨论了这个问题；您可能需要使用“大小/缩放”->“等距缩放”选项。

将尺寸转换为等距坐标应该可以解决这个问题。

Names Default To Here(1);

dt = New Table( "Circle Data",
	Add Rows( 72 ),
	Compress File When Saved( 1 ),
	New Script(
		"y coord vs. x coord", JSL Quote(Graph Builder(show control panel(0),
	Size( 540, 540 ),
	Variables( X( :x coord ), Y( :y coord ) ),
	Elements( Points( X, Y, Legend( 4 ) ), Smoother( X, Y, Legend( 5 ) ) ),
	SendToReport(
		Dispatch( {}, "Graph Builder", FrameBox,
			{Add Graphics Script( 2, Description( "" ), Circle( {0, 0}, 1 ) )}

	)

	New Column( "y coord", Numeric, "Continuous", Formula( Sine( :Degree * (Pi() / 180) ) ), Set Display Width( 123 ) )
);

gb = dt << Run Script("y coord vs. x coord");

framebox = Report(gb)[FrameBox(1)];
framebox << Size To Isometric;
