XY Chart: Dual Y-axis possible?

[woter1832]

Hi,

Is it possible to have two Y-axes?

Chat GPT created:

    title "Dual Y-Axis Chart"
    x-axis "X-Axis"
    y-axis "Primary Y-Axis"
    y2-axis "Secondary Y-Axis"
    series "Series 1" on y
    series "Series 2" on y2
    data
        "X" "Series 1" "Series 2"
        1 10 100
        2 20 200
        3 30 300
        4 40 400
        5 50 500

Which "looks" right, but when run in the live editor it errors:

Error: Error: Parse error on line 6:
...Primary Y-Axis" y2-axis "Secondary Y

Expecting 'XYCHART', 'title', 'X_AXIS', 'Y_AXIS', 'LINE', 'BAR', 'acc_title', 'acc_descr', 'acc_descr_multiline_value', 'NEWLINE', 'SEMI', 'EOF', got 'ALPHA'

And from my very limited knowledge, I guess it doesn't know what y2-axis is ☹️

My aim is something similar to this:

Thank you in advance.
