I had same bug with modal dialog: white border around the dialog and somehow solved it with:
contentItem: Rectangle {
anchors.fill: parent
color: "black"
border.width: 1
...
}
Here I solved it by settings margins to zero and wrapping `ChartView` into another `Rectangle` with same background color as setting negative fixed margins is not quite correct as necessary values could be different:
```
Item {
Rectangle {
color: "black"
anchors.fill: parent
}
ChartView {
id: chart
anchors.fill: parent
antialiasing: true
margins { top: 0; bottom: 0; left: 0; right: 0 }
// plotArea: Qt.rect(0, 0, width, height)
backgroundColor: "black"
backgroundRoundness: 0
legend.visible: false
...
}
}
```
Commented out `plotArea: Qt.rect(0, 0, width, height)` might solve the issue as well but it don't: as axis and axis labels disappear in this case for some reason.
