D3.js折线图y最高轴小于最高线

Question

For example, in the line the highest value is 890, but the largest axis is 800.

I tried to fix it by change .ticks() and tickSize(), they cannot change highest value. it seems d3 draw it automatically. Is there any way to make the highest value larger than the highest value in chart?

Answer 1

Currently, what I do is I set it to the nearest 10.

yScale.domain(
    [d3.max(dataset) + (
        10 - (
            d3.max(dataset) % 10 )
        )
    ), 0]
