Exporting data

A binary .qilog record is converted to CSV with the Runtime → Replay data → Export button. The record must be imported first (the Import button); if it is not fully loaded yet, the export loads it by itself.

CSV layout

The file starts with a short header (source file and export time) and continues as a table: the first column is the timestamp and every logged variable has its own column.

Columns are named after the variable Label, values use the invariant format (decimal point), UTF-8 encoding. Open the file in Excel, load it in Python (see CSV post-processing), or in any other tool.

Export from the graph

A quick alternative is exporting directly from the Graph control (context menu) — it saves the currently displayed series data to CSV, or a snapshot of the chart as an image (PNG, SVG…).
