Log Viewer
This log viewer is a general purpose tool for viewing time series data. We needed a way to easily plot and scale serial port data for numerous embedded projects.

LogViewer V3 for Windows
Getting Started
TBD
Features
Load Data
Software will load *.txt, *.csv and *.log files with commas or spaces as delimiters. No limit for how many data categories.
AUTOSCALE
Checking the autoscale function will try to make the data readable by normalizing it to [0,100]. Data with negative values will be normalized to [-100,100]. The scaling factor will be displayed and can be edited by the user individually for each data category.
SCROLL
Checking the scroll function will limit the x-value on the display to n number of points, making it easier to view a sliding window of data points.
Data Format
Data-Formats can be loaded and saved. A data format contains all of the scaling values and names of each column.
