P3: Somewhat important Description
- Create a QML project
- Add widgets to Qt in .pro file ( mine is QT += quick widgets )
- Switch to QApplication from QGuiApplication in main.cpp
- Add ChartView
- Set legend.markerShape to Legend.MarkerShapeFromSeries
- Add a BarSeries with multiple BarSet elements
- Add a LineSeries
- Run
Lines and scatters are fine, but rectangle fill color seems transparent ( tried with gray background too and the result is gray )
Following is the code I tried. It is a compilation of examples.
import QtQuick 2.12 import QtQuick.Controls 2.12 import QtQuick.Window 2.12 import QtCharts 2.3 ApplicationWindow { visible: true width: 640 height: 480 title: qsTr("Chart Legend Bug Test") Item { anchors.fill: parent ChartView { anchors.fill: parent legend.alignment: Qt.AlignBottom legend.markerShape: Legend.MarkerShapeFromSeries antialiasing: true BarSeries { id: mySeries axisX: BarCategoryAxis { categories: ["2007", "2008", "2009", "2010", "2011", "2012" ] } BarSet { label: "Bob"; values: [2, 2, 3, 4, 5, 6] } BarSet { label: "Susan"; values: [5, 1, 2, 4, 1, 7] } BarSet { label: "James"; values: [3, 5, 8, 13, 5, 8] } } LineSeries { name: "LineSeries" XYPoint { x: 0; y: 0 } XYPoint { x: 1.1; y: 2.1 } XYPoint { x: 1.9; y: 3.3 } XYPoint { x: 2.1; y: 2.1 } XYPoint { x: 2.9; y: 4.9 } XYPoint { x: 3.4; y: 3.0 } XYPoint { x: 4.1; y: 3.3 } } SplineSeries { name: "SplineSeries" XYPoint { x: 0; y: 0.0 } XYPoint { x: 1.1; y: 3.2 } XYPoint { x: 1.9; y: 2.4 } XYPoint { x: 2.1; y: 2.1 } XYPoint { x: 2.9; y: 2.6 } XYPoint { x: 3.4; y: 2.3 } XYPoint { x: 4.1; y: 3.1 } } AreaSeries { name: "Russian" upperSeries: LineSeries { XYPoint { x: 2000; y: 1 } XYPoint { x: 2001; y: 1 } XYPoint { x: 2002; y: 1 } XYPoint { x: 2003; y: 1 } XYPoint { x: 2004; y: 1 } XYPoint { x: 2005; y: 0 } XYPoint { x: 2006; y: 1 } XYPoint { x: 2007; y: 1 } XYPoint { x: 2008; y: 4 } XYPoint { x: 2009; y: 3 } XYPoint { x: 2010; y: 2 } XYPoint { x: 2011; y: 1 } } } ScatterSeries { id: scatter1 name: "Scatter1" XYPoint { x: 1.5; y: 1.5 } XYPoint { x: 1.5; y: 1.6 } XYPoint { x: 1.57; y: 1.55 } XYPoint { x: 1.8; y: 1.8 } XYPoint { x: 1.9; y: 1.6 } XYPoint { x: 2.1; y: 1.3 } XYPoint { x: 2.5; y: 2.1 } } } } }
I am also experiencing the same behavior in my own project; which contains three barsets and a line series in a single chart view.
