Which of the messages in my research results requires a graph? Recognizing how graphs improve on simple statistics and convey much more information.
How can I best convey the message? Striving for clear vision by choice of graph, scaling, discrimination of data series, minimizing non-data ink, avoiding chart junk. Striving for clear understanding through a balance between data and explanation.
Is my graph truthful? Creating a direct proportion between graph and data quantities, avoiding forms prone to misinterpretation, labels to prevent ambiguity; keeping data in context, avoiding more dimensions in the graph than in the data.
