Visualization: ggplot calls to visualize central effects

[psokolhessner]

Consistent visualizations of the effects of acute and chronic stress on trust decisions and ratings are needed for @sjhaats's thesis presentation and thesis document. There is a possible starter template ggplot call to produce a graph for trust ratings.

Describe the solution you'd like

• Develop the trust rating ggplot call to match existing desired color scheme in presentation (no teal).
• Leverage similar approach for overall trust game sharing
• Leverage similar approach for previous trial effects (if possible; might need multiple kinds of lines, i.e. solid & dashed, to represent $ shared after sharing vs. after not)

Describe alternatives you've considered
A graph of effect sizes (and not final DV, e.g. $ shared or rating given) may be simpler esp. for effects of previous events on subsequent actions.
