This has been fixed for the next build:

Chart now has separate typography properties for the title and legend:
Chart1.TitleFontName = "Arial"
Chart1.TitleFontSize = 48
Chart1.LegendFontName = "Arial"
Chart1.LegendFontSize = 14
I’ve also hidden the inherited generic FontName and FontSize controls from the Chart inspector, since those were misleading for Chart. Existing projects that had already set FontName / FontSize on a Chart will be migrated on load: those old values will become TitleFontName / TitleFontSize, so your existing title styling should carry forward.
