Add support of []int to plot axis types

[ArtemkaKun]

Describe the feature

Currently plot sumtypes XType and YType correspondingly represent values of the X and Y axis have definition []f64 | []string. These sumtypes also should support []int type

Use Case

For example, Is V still fast? values are ints, and when someone wants to use it for plot they need to be converted to []f64 which adds complexity to the code and hits performance.

Proposed Solution

type AxisType = []f64 | []string | []int

pub type XType = AxisType

pub type YType = AxisType
