ChartZ are an evaluative accountability tool that work in conjunction with your VibeMeter to produce linear representations of your relationships over time. Each score your Vibe receives on your VibeMeter is plotted on a line graph in your ChartZ to keep a visual record of your relationship or dates. What’s more, you can use your ChartZ to visually compare your own evaluations of a particular Vibe to your Entourage’s evaluations and really keep yourself in check. Your ChartZ can reveal your relationship’s progress, stability, decline or turbulence.
