The dotted line in graphs is the subtle signal that trends are shifting or projections are tentative. Use 📈🔵🔴 when showing rising but uncertain data, or 📉🔶🔷 to emphasize a decline with caution. In presentations or reports, 📉📏📊 can underline measured analysis, while 📊🔗🔴 suggests linked data points that need closer inspection. These combos fit well in professional chats or financial updates where nuance matters.
