Unsolved Glow and ChartView
-
Im trying to get glowing LineSeries in chartview. On the start everything is ok, but with every time when i update data(append new value to the series) glowing area is expanding. It looks like its overpaiting glow effect on glow effect. How to fix it ? Below my test code. Testing on raspberry pi 3. Gif with example execution
import QtQuick 2.0 import QtQuick.Controls 2.2 import QtCharts 2.2 import QtGraphicalEffects 1.0 Page { id: window visible: true width: 800 height: 480 property var index: 0 LinearGradient { anchors.fill: parent start: Qt.point(0, 0) end: Qt.point(parent.width, 0) gradient: Gradient { GradientStop { position: 0.0 color: "black" } GradientStop { position: 1.0 color: "#011c3a" } } } ChartView { id: chartView backgroundColor: "transparent" anchors.fill: parent ValueAxis { id: valueAxisX min: 0 max: 10 visible: false } ValueAxis { id: valueAxisY min: 0 max: 10 visible: false } LineSeries { id: series axisX: valueAxisX axisY: valueAxisY color: "blue" } Glow { anchors.fill: chartView radius: 18 samples: 37 color: "#15bdff" source: chartView } Timer { interval: 500 running: true repeat: true onTriggered: { series.append(index, index) index++ } } } }
