Advanced LS3 Graph Generator - CSV to PNG converter (v4.0) ©️LineGrip Corp.
Generate high resolution graphs (1680px PNG) from LS3 log files.
Log meta data is currently displayed correctly for log files from firmware versions v2.530 to 4.240.
For earlier firmware versions the graph generation, serial, date, time will work fine, the other meta data might be scrambled.
CSV-Logs exported from the LS3-App can also be processed, HOWEVER, these are always treated as 40Hz logs!
Download logs directly from LS3 via USB cable with the LS3 Log Extractor
Merge multiple consequtive logs with the LS3 Log Merger
Enjoy 😃 Andy R.
📤 Up-/Download Instructions
Drag and Drop LS3 log files (CSV) to the grey area or use the "File Selector" button to upload.
Multiple CSV file dropping/uploading is supported!
Click the blue button below a graph to download or click "Download All" button for all graphs (ZIP file).
📈 Graphs Explained
The upper graph (in the grey area) is interactive — point on it to read values.
A red dot in the graph marks the max. load, a green dot the min. load (only if there's one unique minimum).
When adding multiple single CSVs, the most recent generated PNG is at the top of the list, the first one at the bottom.
To clear the generated graphs simply reload the page in your browser.
☯️ Smoothing Algorithms
Savitzky-Golay is more precise (retains spikes well) therefore flattens less and shows more detail.
Moving Avg is your choice for nice, flat curves if you just need the "big picture" of what happened.
The heavier the intensity, the less meaningful the Y axis becomes, even though the curve is visually correct. In other words: the peaks may reduce due to the flattening (deviation between max load and plottet curve).
Intensity Extreme is kind'a experimental. It may move the max/min peaks, and thus may provide less valuable data. It could work well for 1280Hz logs.
In essence: The lower the scan rate, the lower you should choose smoothing. Thus, for low scan rate logs avoid heavy smoothing, whereas heavy (and even extreme) may give you good results for high scan rate (always check the peaks).
Pro-Tip 40Hz: Savitzky-Golay Light-Moderate smooths jagged graphs nicely and barely moves peaks/lows noticeably.
