Adding Trend Lines and Associated Equations to Scatter Plots
Being able to add a trendline to a *scatter chart* would improve my Power BI visualizations. Having a trend line and the associated equation allows you to see the relationship in the graph more clearly. Doing this in Excel isn't the same... I'd want my audience to have the benefits of seeing the data in Power BI. Hopefully at least a linear trend line can be added, but it'd make sense to have all kinds of trend lines (exponential, log, etc.).
