Hello,

The problem

The problem is about the qml linter. When I setting some properties to `ChartView` from `QtCharts 2.0`, The linter will give mistake error reports.

More specificly, the properties i am setting are `margin` and `legend`. For example, i want custom the `ChartView` by using code below:

ChartView{
 id:test
 margin.top:3
 legend.alignment: Qt.AlignBottom
 }

The `Qt Creator` embedded qml linter will report errors, like this

ChartView{
 id:test
 margin.top:3 error: "margin" doesn't have members.(M17)
 legend.alignment: Qt.AlignBottom error: "legend" doesn't have members.(M17)
 }

I am sure that syntax is correct because they really do their job (change the legend position and decrease default margin size)

BUG reproduction

I can reproduct the bug by opening the offical DEMO `qmlchart`, and open `view1.qml` , the qml linter will give me an error at line 44.This line is

legend.alignment: Qt.AlignBottom

Error info is:

"legend" doesn't have members.(M17)

and I have uploaded an screenshot showing this BUG.

Thank you.
