Mixed Font Style for Line Chart of X-Axis

[osolano]

I was wondering if the following was possible. Basically on the x-axis I have a set of dates with a string like
05 Sat
I wanted to do two things, one is to wrap the string so that the day number is on 1 line and weekday is on the next.
The next thing I wanted to do is see if I could make the first line a bigger font size then the second line. So basically 05 is larger than Sat

x axis support wrapping already, but I am not 100% sure it can achieve your goals, just give a try first.
checkout if below property can help you, or at least guide you how to customize your own:
also look at internal func drawLabels

    /// the position of the x-labels relative to the chart
    public var labelPosition = XAxisLabelPosition.Top

    /// if set to true, word wrapping the labels will be enabled.
    /// word wrapping is done using `(value width * labelRotatedWidth)`
    ///
    /// *Note: currently supports all charts except pie/radar/horizontal-bar*
    public var wordWrapEnabled = false

    /// - returns: true if word wrapping the labels is enabled
    public var isWordWrapEnabled: Bool { return wordWrapEnabled }

    /// the width for wrapping the labels, as percentage out of one value width.
    /// used only when isWordWrapEnabled = true.
    /// 
    /// **default**: 1.0
    public var wordWrapWidthPercent: CGFloat = 1.0

using two font seems not supported yet. Since this is a little customization-oriented. You could override some methods and add new font size property to do so.
