Last LineChart y-label not being rendered

[ryanschneider]

In 3.0 (using master from commit 3a2da1b) I'm seeing that the last y-label in my charts is not being rendered.

I've tracked down was I think is the cause to this line:

https://github.com/danielgindi/Charts/blob/a34d55a5c9d16c1f4f6f48f2148b4e88902c55d0/Source/Charts/Renderers/LineChartRenderer.swift#L552

I think the stride(from:to:by) should be a stride(from:through:by) (use through, not to), like so:

    open override func drawValues(context: CGContext)
    {
                //....
                for j in stride(from: _xBounds.min, through: Int(ceil(Double(_xBounds.max - _xBounds.min) * phaseX + Double(_xBounds.min))), by: 1)
                {
                    guard let e = dataSet.entryForIndex(j) else { break }

This edit works locally for me, I'll send a PR for the change as well here in a minute, but haven't done an extensive audit for the other chart types to see if a similar issue exists there.

This is dup to #1323
I also mentioned in #1323:

This did fix the missing label, however, I found a new issue that when zoomed in, the animation on x axis is not in sync: the value text will jump out first and then come with the line. Changing back to to the animation will be good. awkward...

Closing as dupe of #1323.
