How to set y-axis auto scaling with no fractional numbers? #856

Closed ile closed 10 months ago

Thanks for the great library. This is just a question, hope it's ok:

Is it possible to set the y axis so that it uses auto scaling, but it wouldn't print fractional numbers?

On this chart, it can still print the grids as they are, but it just wouldn't print those 272,5 and 267,5 numbers. So it would look like this:

what ticks/grid do you want to see when your data range is {min: 264.5, max: 264.9}

Well, my data range wouldn't be like that. The data represents "the number of tasks", so it's always integers.

That's why it feels strange to see floating point numbers when "number of tasks" can't be anything like that.

So, if there was a setting like { int: true } that could help.

I can also fork the library and do my own change.

you can control what tick multiples can be chosen by providing your own via axis.incrs: https://jsfiddle.net/duym25wh/1/
