Ask better questions before building a dashboard
Decide what a chart should help someone understand before choosing its colors.
A dashboard is most useful when its purpose is clear. Start with a question, then choose the information that helps answer it. ## Who will use it? A person reviewing a monthly summary may need a different view from someone checking daily entries. Write down the intended audience and the decision they need to make. ## What does each measure mean? Define the time period, source, and unit. If values are missing, show that clearly instead of treating every blank as zero. ## Keep the first version focused Choose a small number of useful views. Label charts directly and include a table when exact values matter. Avoid relying on color alone to communicate meaning. ## Try a synthetic example Use fictional categories and values to review the layout. Never move patient-level or confidential workplace data into a public demonstration. This article is a demonstration draft for the website.
