Line chart in QT 5.6

[KazuoAsano]

It find Line chart with Qt Chart in Qt example.
You will select an example with mode selector on the left side of Qt Creator.
And When you search at "Callout", you can use the sample of Line chart.

The same contents can be seen on the Web!

Can you upgrade to a newer Qt Version? E.g. 5.9.x or 5.12? I'm not sure if 5.6 already contained the QtCharts module (which is GPL licenced, by the way). Edit: 5.6 already contained QtCharts.

Is it possible to integrate QChart and If possible then how can i implement it?
Or how can i use canvas for the same?

Of course, always :)

There are other plotting libraries that work well with Qt, e.g. qcustomplot. You can just google them.

Hi
Should in not be installer then ? (for 5.6)

or am i just blind ?:)

[aha_1980]

@mrjj Interesting. Reading http://blog.qt.io/blog/2016/01/18/qt-charts-2-1-0-release I thought that would be the case.

So, my recommendation to upgrade to 5.9.x or 5.12 stays :)

@aha_1980
Ahh, from your link.
"With Qt 5.7 release the packages will include a pre-built version of the module"
Which Installer agrees with.

[aha_1980]

@mrjj ok, reading helps, as usual :)

So with 5.6 you have to build from source.

Thk! @aha_1980 , @mrjj it was also a very good learning , me too.

@drd1988on ,
OK, I think that It may be hard to build Qt Chart at Qt5.6.

My others solution, I will provide Qwt(Qt Widgets for Technical Applications) library(no official library on Qt).

http://qwt.sourceforge.net

Qwt contain an easy 2D plots framework.
ex : line plot
http://qwt.sourceforge.net/curvescreenshots.html

Qwt library also need building, but it may be easier than Qt Chart build at Qt5.6.
I'm also using from Qt4.8. and it's useful library for graph creation.
