customAxisMin is Deprecated in latest Charts.

在最新的图表中，customAxisMin被弃用。

Use property axisMinValue instead!

使用属性axisMinValue相反!

Take a look at below properties. Should be able to solve your problem.

看看下面的属性。应该能够解决你的问题。

/// A custom minimum value for this axis. 
/// If set, this value will not be calculated automatically depending on the provided data. 
/// Use resetCustomAxisMin() to undo this. 
/// Do not forget to set startAtZeroEnabled = false if you use this method.
/// Otherwise, the axis-minimum value will still be forced to 0.
public var customAxisMin = Double.NaN

/// Set a custom maximum value for this axis. 
/// If set, this value will not be calculated automatically depending on the provided data. 
/// Use resetCustomAxisMax() to undo this.
public var customAxisMax = Double.NaN

/// if true, the y-label entries will always start at zero
public var startAtZeroEnabled = true

For example:

例如:

_chartView.leftAxis.customAxisMax = 35;
_chartView.leftAxis.customAxisMin = 0;

or _chartView.leftAxis.startAtZeroEnabled = YES;

或_chartView.leftAxis。startAtZeroEnabled =是的;

For Charts 3 (tried on Charts 3.0.2), this works:

对于图表3(在图表3.0.2中进行了尝试)，这是可行的:

chartView.leftAxis.axisMinimum = 0

By default there is a rightAxis as well (at least for bar charts) and the grid won't be aligned if you don't also set:

默认情况下，也有一个右对齐(至少对于条形图)，如果你不设置，网格就不会对齐:

chartView.rightAxis.axisMinimum = 0

Note: I wrote this as a comment initially but I think it should be an answer to be easier to find for people who end up here from Google.

注意:我最初是作为评论写的，但我认为这应该是一个更容易找到的答案，因为人们从谷歌结束。
