Unsolved Dynamic ChartView updating
-
In my program data for chart are producing in c++ and the QML function is called like this
QMetaObject::invokeMethod(view.rootObject(), "readValues", Qt::DirectConnection, Q_ARG(QVariant, QVariant::fromValue(list)));
then data series are appended in readValues function
Item{ id: chart ChartView { id: chartView width: parent.width height: parent.height theme: ChartView.ChartThemeLight antialiasing: true legend.visible: false ValueAxis { id: axisX titleText: "D N I" labelsFont: Qt.font({pointSize: 12, bold: true}) min: 0 max: 200 tickCount: 21 labelFormat: "%.0f" } ValueAxis { id: axisY labelsFont: Qt.font({pointSize: 12, bold: true}) min: 0 max: 14000 tickCount: 8 labelFormat: "%.0f" } LineSeries { id: infectedSeries axisX: axisX axisY: axisY color: "blue" width: 4 } } function readValues(collection) { for (var i = 0; i < collection.length; i++) { infectedSeries.append(i, collection[i]); console.log("Array item: " + i + " val " + collection[i]); } // chartView.update(); } }
There is no effect on chart. It is strange because on the console logs are printed properly
Thank you in advance
