Designing Figures and Graphs
Carefully consider how you want to present your results visually in your poster. There are a variety of ways to add emphasis to figures below are examples.
From: Harold, J., Lorenzoni, I., Shipley, T. et al. Cognitive and psychological science insights to improve climate change data visualization. Nature Clim Change 6, 1080–1089 (2016). https://doi.org/10.1038/nclimate3162
These methods can also be used in tables of data to draw the viewer's attention to interesting findings.
Avoid including a background on your chart and remove extraneous information as much as possible. Keep in mind a poster presentation is not a formal lab write up. Do you need to label that axis or is the label implied in the chart title (or vice-versa)?
Use a similar approach in formatting tables. Use color or other ways to direct visual attention to the information that really matters.
