When you select a series in a chart, there is a formula in the formula bar:

=SERIES(etc.)

This formula has four parameters: Series Name, X values, Y values, plot
order. If it's a bubble chart it has a fifth parameter for bubble size.

You can edit these formulas right in the formula bar, you can copy a
formula, select the plot area, and paste the formula into the formula bar to
add it to the same or a different chart. And you can simply select the plot
area and start writing your own series formula.

Here's an article about the chart series formula:

Can we write or edit graph's series instead of selecting the required
cells
by setting a formula that reflects the required cells to be selected?
