Email SupportScatter Plot helps you find and quantify relationships between variables. Enter up to four columns of data, see a correlation matrix across every pair at a glance, and pick the one worth a closer look — then get a fitted curve (linear, polynomial, logarithmic, exponential, or power), its equation, and goodness-of-fit statistics (R², adjusted R², p-value).
Enter data by typing, speaking, or scanning a photo, then get clear results with plain-language explanations designed for anyone from a rookie engineer to an experienced quality professional.
Scatter Plot requires iOS 16 or later.
Photo and handwriting recognition work best with printed or clearly written numbers, good lighting, and no digital zoom. For handwritten data, always double-check the recognized values before calculating.
Every fit type is tried, and the one with the highest adjusted R² — R² penalized for extra parameters — is marked BEST FIT. That keeps a more complex curve from winning just for being more complex; it only wins if it genuinely fits better.
