Plottern gives you simplicity and interactivity which Spreadsheets lack. Underneath the simple GUI is a set of powerful tools to help you reveal new insights in your data.
Basic features
Import multiple CSV (Comma separated) and TSV (Tab separated) files
Import multiple XLS/XLSX Excel files
Select series across one or more worksheets
Select multiple series across multiple files
Chose from interactive line, scatter or bar charts
Drag to zoom in on the regions which interest you
Screenshot areas of interest with 1 click
Independently position and scale multiple Y axis series
X axis can plot row number (index) or another series in your data
Every series can be positioned independently on the X axis, ideal for aligning and comparing signals
Isolate sections of data and export snippets to CSV file
Merge multiple files or series into 1 new CSV file
Auto-scale all axes independently
Regular or Log scales on both axes
Performance
Quickly snip large, bulky files down to just the data you want
Processing and storage is done locally for the fastest performance
Utilise multiple threads for the best performance with large data sets
Work without a limit on file size or number of rows or columns
Compare data
Plot as many series as you want on a single graph
Spot patterns by overlaying series from multiple files or sources
Shift and align series with the mouse or numerically
Align peaks and other points of interest with a click
Automatic updates
Plottern is under constant development with new features being release regularly
The live update feature means you will always have access to the latest features with 1 click.
Advanced features
Every math operation or filter creates a new data series so you never lose your original data
Combine any of the advanced features to create new data and find patterns and trends
Find new insights using custom expressions
Derive new data from two or more datasets by writing your own expressions
Powerful built-in Mathematical Expression Engine
Create offsets or correction factors
Multiply or divide to create friendly units of measurement
Basic operators, i.e.: +, -, *, ^, !
Boolean logic operators i.e.: or, and, xor
Binary relations i.e.: =, <, >
Math functions (large library of 1-arg, 2-arg, 3-arg – functions) i.e.: sin, cos, Stirling numbers, log, inverse functions
Constants (large library), i.e.: pi, e, golden ratio
Filter out the noise
Filter out unwanted values using binary relations such as =, <, >, <=, >=, <>
Find trends in your data with moving averages
Calculate moving averages of any period from any series
Calculate as many moving averages as you need
Moving averages are created as new series which can then be filtered or have further math applied to them
