Array of QLineSeries

deleted286

How can i put my series into an array?

series->setColor(Qt::blue);
series->setName(sr);
series1->setName(sr1);
series1->setColor(Qt::green);
series2->setName(sr2);
series2->setColor(Qt::yellow);
series3->setName(sr3);
series3->setColor(Qt::darkBlue);
series4->setName(sr4);
series4->setColor(Qt::cyan);
series5->setName(sr5);
series5->setColor(Qt::black);
series6->setName(sr6);
series6->setColor(Qt::gray);
series7->setName(sr7);
series7->setColor(Qt::red);


chart->addSeries(series);
chart->addSeries(series1);
chart->addSeries(series2);
chart->addSeries(series3);
chart->addSeries(series4);
chart->addSeries(series5);
chart->addSeries(series6);
chart->addSeries(series7);
chart->legend()->setVisible(true);
//chart->setTheme(QChart::ChartThemeBlueIcy);
chart->setAnimationOptions(QChart::AllAnimations);

axisX->setTickCount(5);
axisX->setRange(0, +2);
chart->addAxis(axisX, Qt::AlignBottom);
series->attachAxis(axisX);
series1->attachAxis(axisX);
series2->attachAxis(axisX);
series3->attachAxis(axisX);
series4->attachAxis(axisX);
series5->attachAxis(axisX);
series6->attachAxis(axisX);
series7->attachAxis(axisX);


axisY->setTickCount(5);
axisY->setRange(0,2);
chart->addAxis(axisY, Qt::AlignLeft);
series->attachAxis(axisY);
series1->attachAxis(axisY);
series2->attachAxis(axisY);
series3->attachAxis(axisY);
series4->attachAxis(axisY);
series5->attachAxis(axisY);
series6->attachAxis(axisY);
series7->attachAxis(axisY);


chartView->setRenderHint(QPainter::Antialiasing);
ui->gridLayout->addWidget(chartView);

I've tried to add

QLineSeries *series[7];

on my header. And after that, i wrote a for loop to cpp

for(int i=0; i<8; i++)
{
//do something with series[i]
}

but it says me series[1] doesnt declare in this scope

@suslucoder said in Array of QLineSeries:

I've tried to add

Where?

"but it says me series[1] doesnt declare in this scope" - again: where did you declare the array?

@jsulm in

void VeriGoster::Timer_Slot()
{
    static float q_x=0;
    auto Timer = [=] (QQueue<double> &queue, QLineSeries &series)->void
    {
        if(!queue.isEmpty())
              {
                 double num=queue.dequeue();
                 q_x += 0.1;
                 series.append(q_x, num);
                 chart->update();
                 chart->scroll(6,0);
                 qDebug() << q_x << num;
               }
    };

     Timer(queue, *series);
     Timer(queue1,*series1 );
     Timer(queue2, *series2);
     Timer(queue3, *series3);
     Timer(queue4, *series4);
     Timer(queue5, *series5);

@suslucoder
And where does the code you show generate

but it says me series[1] doesnt declare in this scope

?

Where is the for loop you say you are trying?

Also, where does it use the

QLineSeries *series[7];

you say you are having trouble with? I do not see it using any array of anything, which is what your whole question is about...
