Figure 2.
The two panels are labelled a and b. Panel a is labelled nationwide and shows a circular radial chart with concentric arcs for years twenty eleven, twenty thirteen, twenty fifteen, twenty seventeen, twenty nineteen, and twenty twenty one. Radial tick labels run from zero to zero point one four in steps of zero point zero one. Each arc segment displays numeric values including zero point zero four zero two, zero point zero four zero five, zero point zero five two four, zero point zero six four eight, zero point zero six nine seven, zero point zero six eight one, zero point zero six eight three, zero point zero seven six, zero point zero eight seven six, zero point zero eight two four, and zero point one three five five. Panel b is labelled regions and contains three horizontal line charts with a shared horizontal axis labelled year from twenty eleven to twenty twenty one. The eastern chart shows labelled points zero point zero four five, zero point zero four seven, zero point zero five seven, zero point zero six nine, zero point zero seven five, zero point zero seven four, zero point zero six nine, zero point zero seven six, zero point zero eight eight, zero point zero eight two, and zero point one four two. The central chart shows labelled points zero point zero four one, zero point zero three nine, zero point zero five seven, zero point zero six four, zero point zero seven one, zero point zero seven one, zero point zero seven two, zero point zero eight zero, zero point zero nine one, zero point zero eight six, and zero point one three six. The western chart shows labelled points zero point zero three five, zero point zero three five, zero point zero four five, zero point zero six one, zero point zero six two, zero point zero six zero, zero point zero six five, zero point zero seven three, zero point zero eight five, zero point zero eight zero, and zero point one two eight.The overall GTCI value in China
