plotting a binary file

[Alex22]

Hi, I want to plot a binary file. It has 11 columns that the first column is time. each column has 20 rows. I want to plot each column on the first column (time), in Qt Widgets Applications so I created a project of Qt Widgets Applications.

I need:

1- for plotting this binary file I have no idea. please help me.
2- for each column I must put Check Box that by checking it and pushing a Push Button, plots it. (if I check for example 5 Check Boxes, it must plot 5 related signals).

please help me.

You could look at Qwt for various styles of plot that suit technical applications (your app seems to be)

For the checkable list you could look at a QListWidget and set each QListWidgetItem's flags to include Qt::ItemIsUserCheckable.
A QPushButton with a slot handling the click event can trigger the plotting.
