automatic value for Y axis

[Daniel Silva]

Hi,

I’m building a generic chart function and having a problem with maximum and minimum.
Sometimes I have a value, sometimes don’t.
Is there any away to set a automatic value?

axisY:{
minimum: max===undefined ? null : Number(max),
},
or
axisY:{
minimum: max===undefined ? auto: Number(max),
},

Br,
Daniel

Apparently undefined works :)
Not sure why yesterday was giving problems.

When checking for undefined, its better to go with below code which works across browsers and devices.

typeof(max) === 'undefined'

I never had problems with that, probably because most of my variables are properties.
container.max===undefined
Not sure what is the difference :/ but will take the advice into account, thanks.
