centered()

QRectF QwtPlotLayoutEngine::Dimensions::centered	(	const QRectF &	rect,
		const QRectF &	labelRect
	)		const

Center a label rectangle within available space / 在可用空间内居中标签矩形

This method adjusts the label rectangle to be centered horizontally within the available space after accounting for Y axis dimensions.

此方法调整标签矩形，在考虑Y轴尺寸后在可用空间内水平居中。

Parameters

rect	The available rectangle / 可用矩形区域
labelRect	The label rectangle to center / 要居中的标签矩形

Returns

Centered label rectangle / 居中后的标签矩形

(

const QRectF &

rect

)

const

Calculate inner rectangle after accounting for axis dimensions / 计算考虑轴尺寸后的内部矩形

This method calculates the available space for the canvas after reserving space for all axes.

此方法计算为所有轴保留空间后，画布的可用空间。

Parameters

rect	The outer rectangle / 外部矩形区域

Returns

Inner rectangle for canvas / 画布的内部矩形区域

setDimAxis()

void QwtPlotLayoutEngine::Dimensions::setDimAxis	(	QwtAxisId	axisId,
