[Feature] How to get the axis range when datazoom scales it?

What problem does this feature solve?

Hopefully the axis range could be known when it’s changed. I have y-axis scale set to true, and enabled datazoom. When I zoom or pan the chart, clearly the y-axis’s range changes too. Now I need to know the new range. I tried to listen to datazoom event but it doesn’t look like any properties in the option could give me the values.

chart.on("datazoom", params => console.log(chart.getOption().yAxis[0]))

From the output I cannot see any information showing the y-axis range. Is there a way I can get it?

What does the proposed API look like?

Add a range property in the yAxis option:

yAxis: {
    range: [currentMin: number, currentMax: number]
}

@bbcfive This API is not exposed, so you have to use as any or // @ts-ignore to disable the TS check.

hi @plainheart, but how can I solve the ts error?
