Create line chart with Visual Studio 2015 and Qt 5.9

[Kanguru]

Hello,
I am trying to create a line chart in Visual Studio 2015 by using Qt 5.9.

I already set up the .pro file, but still get a problem with QtLib.

In main.cpp

In .pro file

And the error

I appreciate any help from all of you

Thank you

does using the macro instead help:

QT_CHARTS_USE_NAMESPACE

int main(int argc, char *argv[])

Do the example chart projects work for you? If they do that will be a simple test of finding differences of broken vs working...

[6thC]

Where I do use Charts obejcts, I also use a namespace on that class (as you are main):

using namespace QtCharts;
class ...

Again, comparing the example apps to mine worked a treat for me.

@Kanguru Can you post the compiler/linker output? It looks like your app is not linked against QtChart lib.
