Hello Alaa

RingQt support QChart & QChartView classes

We could add examples about using them in the future

But I don't have the time to do this in the next future

For Now use QML : https://github.com/ring-lang/ring/tree/master/samples/UsingQML

This folder : https://github.com/ring-lang/ring/tree/master/samples/UsingQML/sample10

Greetings,

load "guilib.ring"

new qApp {

   w = new qWidget() {

       setWindowTitle("Using QML - Display Chart") resize(650,650) move(100,100)

       

// oQuick.addseries("Magnitude (Column 1)", [0, 1])

set0= QBarSet ("X0")

       set1 = QBarSet ("X1")

       set2 = QBarSet ("X2")

       set3 = QBarSet ("X3")

       set4 = QBarSet ("X4")

set0.append([1, 2, 3, 4, 5, 6])

       set1.append([5, 0, 0, 4, 0, 7])

       set2.append([3, 5, 8, 13, 8, 5])

       set3.append([5, 6, 7, 3, 4, 5])

       set4.append([9, 7, 5, 3, 1, 2])

series = QHorizontalBarSeries()

       series.append(set0)

       series.append(set1)

       series.append(set2)

       series.append(set3)

       series.append(set4)

       oQuick.addSeries(series)

       oQuick.setTitle('Horizontal Bar Chart Demo')

months = ['Jan', 'Feb', 'Mar', 'Apr', 'May', 'June']

axisY = QBarCategoryAxis()

axisY.append(months)

       chart.addAxis(axisY, Qt.AlignLeft)

       series.attachAxis(axisY)

axisX = QValueAxis()

       oQuick.addAxis(axisX, Qt.AlignBottom)

       series.attachAxis(axisX)

chartView = QChartView(oQuick)

       chartView.setRenderHint(QPainter.Antialiasing)

       w.setCentralWidget(chartView)

w.chartView=new Qchartview(oQuick)

}

       //oLayout = new qVBoxlayout() {
