Draws a line that ends in a rectangular callout from where you drag in the current document. The text direction is horizontal. Drag a handle of the callout to resize the callout. To change a rectangular callout to a rounded callout, drag the largest corner handle when the pointer changes to a hand. To add text, click the edge of the callout, and then type or paste your text.
在当前文档中绘制一条线，从拖动的位置开始，在希望显示矩形图例的位置结束。文字为水平方向。拖动图例的控点可以修改图例的大小。要将矩形图例修改为圆角图例，请在指针变为手形时拖动最大的角控点。要加入文字，请单击图例的边线，然后键入或粘贴文字。
