Android Question Using data from xChart database

Itila Tumer · Apr 22, 2019

Hello there,

I developed a small application.
I have columns in the ID Data TestAdi names in my database.

I'm bringing IDs to Spinner.
I got the values from the DATA column according to the selected ID.
I shred the data I got and transferred it to the list.

As I learned, the X axis takes time.
The Y-axis values take Direction = Rnd (0, 500).
I want to send the values of the Y axis with the list I received from my database.

@klaus waiting for your help.

I was waiting for your answers in this thead How do I draw graphics?
I asked you there several questions, you have never answered, why!?

I looked at your project.
And again have the same questions:
What exactly do you want to do?
What kind of data are in the array you get when selecting in the Spinner.
Are these Y values?
If yes, do you want to display these data on a chart?
What are the X values?
You use a timer for a dynamic chart, do you really want or need it?

I tryed to guess some answers and changed your project.
But I am very frustrated, trying to help whithout knowing if this is what you expect.

As I learned, the X axis takes time.

No, the X values are Strings.
In xChart1.AddLineMultiplePoints(i, Array As Double(lstData.Get(i)), True)
If you set True as the last parameter, the X Value is displayed.
