In case anyone else falls into this error, i found the solution was that my Debug build in Visual studio was linked against QChart.lib, not QChartd.lib. Once i changed this it worked.

Worth linking this topic to the answer documented on StackOverflow: https://stackoverflow.com/questions/46886443/scrollable-qml-charts

@rahulch_pp Try to comment the line 18 of main.qml " animationOptions: ChartView.AllAnimations".
It seems to be buggy from Qt5.12 (and also Qt5.12.1)

do you want to plot the axis and legend? or just the pixels?
and you want to plot the matrix from image or from data?

Works, thank you.

Hi.

Try in your test.h as follows:

#ifndef TEST_H #define TEST_H #include <QtCharts> QT_CHARTS_USE_NAMESPACE #include <QMainWindow> #include "ui_test.h" class test : public QMainWindow { [...]

Do not modify your ui_test.h.

Thanks a lot! solve my problem, it is really easy to foget that!

I've found out that it has already been implemented.
https://bugreports.qt.io/browse/QTBUG-50544

OK so this example is about QLineSeries, not QBarSeries, and there is a reason: QLineSeries has clicked(QPointF) and hovered(QPointF, bool) signals, QBarSeries doesn't.

So I think I'll have to simply implement a BarView that displays the value, using QGraphics framework.

You should have subscribed to the mailing list. You message would have gone through directly.

@Wieland
No problem :)

Hi and welcome to devnet,

How did you compile that module for your BBB ?

@RTjen

which begs to differ, is this a known bug with the Spline function

I don't know, as I said I don't use the module, but you could look here (you can login with your forum credentials).
One thing that caught my eye though is this bug, which doesn't speak well of the implementation of the charts module, as the developer provided some lazy excuse (this is simply implemented by notifying the owner of the destruction).
Anyway, you could either file a bug report or try something else. My father (who uses a commercial license) gave up on the charts and is currently using QCustomPlot, so you could try that if it provides what you're after.

I hope that helps.
Kind regards.

@vladstelmahovsky Thanks! That worked like a charm. It also gave me a good starting for digging into the interaction code and figuring out how the mouse handlers work between QML and C++.

Hello,

Thanks you for the answer.
