The line series of the first data is drawn normally. The second data line is not drawn.

When the model changes, the chart must also be updated.
I wonder how.

I set the Column of the first series mapper to 0, 1.
I set the Column of the second series mapper to 0, 2.
Then it prints normally.
I didn't fully understand the function of setXColumn. What function does it specifically do? I've looked at the documentation, but I don't understand.
