Hi... In the example.. If you see... there is a pushbutton,, first you need take data from combox, then push buttonm to graph. In your app, you need insert a pushbutton, because  you need update chart when you change the period time.

As you can see i have a functional QtChart in my ui and works fine at start up. My problem is when i change the combobox item. I cant figure how to update the data in this chart. I trigger with success my def chart_one_create(self). thnx . — You are receiving this because you commented. Reply to this email directly, view it on GitHub, or unsubscribe.
