@MikhailG posted the same question on StackOverflow and apparently this answer solves it: Possible solution 1: QMargins property designates the minimum area around the plotting area. Try filling this remaining padding by adjusting the child (plot) itself. But what does that mean? -Given that my axes will remain static for a given ChartView, I am thinking that these should be set up in my QML delegate. Is my thinking correct on this? Note: I should add that it is intended for the user to be able to add or remove graphs from the ListView of ChartViews. Apparently, the standard example shown above from the QML documentation does not work for dynamically populated LineSeries because the append(x,y) method of LineSeries seems to convert x and y to real values (even if you dynamically create an XYPoint e.g.

Some chart components can also be presented as polar charts by using the the QPolarChart class that is a specialization of the QChart class or the PolarChartView QML type that is a specialization of the ChartView type. The QML Oscilloscope example has a Timer function in the .qml ChartView file which polls c++ for data, which isn't the approach I'd like to use. As (I believe you've described), I'd like for c++ to collect the data and push it to QML (using the replace() function as you've described). The first crash comes when a ChartView is in a Popup, and the second happens when a ChartView is in a ToolTip, and the crash only happens when the app is quitting, so I'm wondering if the fact that the chart isn't part of a standard qml page (i.e.
