ndscope 0.9.2

Next-generation NDS time series plotting

Next-generation NDS oscilloscope

ndscope is a tool for viewing time series data from the LIGO Network Data Services (NDS). Based on nds2-client and the high-performance pyqtgraph plotting library, ndscope is a able to plot both online and offline data for many channels simultaneously with intuitive mouse pan/zoom support.

Features:

• online mode for raw and trend data
• mouse pan and zoom, with background auto-fetch of new data
• automatic transition to second/minute trend data at appropriate zoom levels
• triggering, for true oscilloscope behavior
• cursors and crosshair in both time and Y axes
• save layout templates in easy-to-use YAML format
• load templates from various legacy formats, including StripTool .stp, dataviewer .xml, and .txt
• enhanced "StripTool mode" with auto-backfill of past data
• NDS2 and NDS1 protocols supports

Left mouse click+drag for pan, and right mouse click+drag for zoom (left/right for in/out in time, and up/down for in/out in Y). Click+drag on axis to retrict pan/zoom to only that dimension.
