For years I have used Google Workspace and Sheets to analyze data. Frequently I wanted to make a chart that Sheets did not offer. So I made an add-in for Google Sheets called FSplots. I am solving a problem for myself, but you are welcome to try it.
FSplots is a fast and convenient way to build advanced scientific and statistical charts that Google Sheets does not directly offer. An easy to use add-on built specifically for the Sheets user who needs more from their data visualizations.
Split-Color Scatter Plots: Color-code your data points automatically by a custom category split (e.g., age range, gender, test group, or month). For "truth & prediction" data models, it automatically calculates Bias, Mean Absolute Error (MAE), and Correlation. With options to add the unity line (x=y), the best fit line, and the best fit equation & R2 value.
Bland-Altman Plots: Map data agreement quickly. Includes point-coloring by group splits, with automated Bias & Limits of Agreement lines and values.
Custom SD Bar Charts: Generate mean and standard deviation bar charts. Unlike native Google Sheets, every bar gets its own SD error bar value.
Interquartile Range charts (IQR): Calculates the median and displays the distribution with 3 options for the whiskers: max min, +-1.5 IQR (standard box plot rule) , & custom percentiles.
100% Secure & Local Processing: All data formatting and mathematical calculations happen entirely inside your spreadsheet. This tool contains no identity or activity tracking, and your data never leaves your Google Sheet.
