信号文档编制

clicked ( point point )

This signal is emitted when the user triggers a mouse event by clicking the point point in the chart. For example:

LineSeries {
    XYPoint { x: 0; y: 0 }
    XYPoint { x: 1.1; y: 2.1 }
    onClicked: console.log("onClicked: " + point.x + ", " + point.y);
}

The corresponding signal handler is onClicked() .

doubleClicked ( point point )

This signal is emitted when the user double-clicks the data point point in the chart. The point is the point where the first press was triggered. For example:

LineSeries {
    XYPoint { x: 0; y: 0 }
    XYPoint { x: 1.1; y: 2.1 }
    onDoubleClicked: console.log("onDoubleClicked: " + point.x + ", " + point.y);
}

The corresponding signal handler is onDoubleClicked() .

hovered ( point point , bool state )

This signal is emitted when a mouse is hovered over the point point in the chart. When the mouse moves over the point, state turns true , and when the mouse moves away again, it turns false .

The corresponding signal handler is onHovered() .

pointAdded ( int index )

This signal is emitted when a point is added at the position specified by index .

The corresponding signal handler is onPointAdded() .

pointRemoved ( int index )

This signal is emitted when a point is removed from the position specified by index .

The corresponding signal handler is onPointRemoved() .

pointReplaced ( int index )

This signal is emitted when a point is replaced at the position specified by index .

The corresponding signal handler is onPointReplaced() .

pointsRemoved ( int index , int count )

This signal is emitted when the number of points specified by count is removed starting at the position specified by index .

The corresponding signal handler is onPointRemoved() .

pointsReplaced ()

This signal is emitted when all points are replaced with other points.

The corresponding signal handler is onPointsReplaced() .

pressed ( point point )

This signal is emitted when the user presses the data point point in the chart and holds down the mouse button. For example:

LineSeries {
    XYPoint { x: 0; y: 0 }
    XYPoint { x: 1.1; y: 2.1 }
    onPressed: console.log("onPressed: " + point.x + ", " + point.y);
}

The corresponding signal handler is onPressed() .

released ( point point )

This signal is emitted when the user releases the mouse press on the data point specified by point 。例如：

LineSeries {
    XYPoint { x: 0; y: 0 }
    XYPoint { x: 1.1; y: 2.1 }
    onReleased: console.log("onReleased: " + point.x + ", " + point.y);
}

The corresponding signal handler is onReleased() .

方法文档编制

append ( real x , real y )

Appends a point with the coordinates x and y 到系列。

QPointF at ( int index )

Returns the point at the position specified by index . Returns (0, 0) if the index is not valid.

insert ( int index , real x , real y )

Inserts a point with the coordinates x and y to the position specified by index in the series. If the index is 0 or less than 0, the point is prepended to the list of points. If the index is equal to or greater than than the number of points in the series, the point is appended to the list of points.

remove ( real x , real y )

Removes the point with the coordinates x and y from the series. Does nothing if the point does not exist.

remove ( int index )

Removes the point at the position specified by index from the series.

removePoints ( int index , int count )

Removes the number of points specified by count from the series starting at the position specified by index .

replace ( real oldX , real oldY , real newX , real newY )

Replaces the point with the coordinates oldX and oldY with the point with the coordinates newX and newY . Does nothing if the old point does not exist.
