y axis range in tsplot

[dkoltg]

In one of our specific graphs, tsplot displays only values below 0 instead of automatically adapting the fitting y axis range:

tsplot("Beschäftigung Urteil"=bau_12$ch.kof.bau.ng08.fx.rgn.tg.q_ql_ass_empl.balance.d12,
       plot_title = "Beurteilung der Beschäftigung",
       plot_subtitle = glue("Kanton Thurgau, Baugewerbe, 2011-2018, Saldo in %"),
       theme = init_tsplot_theme(line_colors = c("#3CA433"),
       subtitle_margin = 1, subtitle_cex = 0.8))
