Figure 4.
The image contains six heatmaps arranged in two rows and three columns, showing varying data over time. Each heatmap is titled with a different combination of variables, including "PWC: ANS - NAR - CLT," "MWC: ANS - NAR - CLT," "PWC: ANS - CLT - ECI," "MWC: ANS - CLT - ECI," "PWC: ANS - ECI - NAR," and "MWC: ANS - ECI - NAR." The horizontal axis represents the time from the year nineteen eighty to twenty twenty, while the vertical axis denotes periods from one to eight. Each heatmap features a gradient colour scale indicating data intensity, with contour lines depicted in black overlaying the coloured regions. The layout is designed for comparison among the different variable combinations across time, facilitating observation of changes in data patterns.PWC and MWC between NARs, CLT, ECI and ANS
Note(s): Graphs of (a)–(f) show the PWC and MWC association of NAR, CLT and ECI with ANS; graphs of (g)–(l) show the PWC and MWC association of ANS, CLT and ECI with NAR; graphs of (m)–(r) show the PWC and MWC association of ANS, NAR and ECI with CLT; graphs of (s)–(x) show the PWC and MWC association of ANS, NAR and CLT with ECI
