1.4.2

Features

• Statistics column editor: Added an info tooltip explaining the requirements for Cp, Cpk, Pp, and Ppk to appear (both LSL and USL must be configured, sufficient data points required).

Bug Fixes

• Fix spec limits from feature series: LSL and USL control lines configured to pull values from a feature series field were not being resolved correctly; capability indices now reflect the actual series value.
• Multi-series spec limit fallback: When a series has no LSL/USL configured, it now falls back to the limits defined for the first series, so a single pair of spec limits applies to all series by default.
• Theme consistency: Replaced remaining hardcoded values with Grafana theme tokens — control line default colors now use the visualization palette (dark-green, dark-red, blue, etc.), hover range and tooltip offset use theme.spacing(), and annotation colors are resolved via theme.visualization.getColorByName().
• Grafana dependency: Minimum required Grafana version bumped to 11.6.10.

1.4.1

1.4.1

• Theme consistency: Replaced hardcoded pixel values and hex color constants with Grafana theme tokens (theme.spacing(), theme.colors.*, theme.visualization.getColorByName()) across editor and tooltip components, improving light/dark mode consistency.
• Documentation: Updated plugin and usage documentation.

• Export to CSV: Export calculated SPC data (statistics, control lines, and histogram buckets) to a CSV file. Available from the download icon in the statistics table header or by right-clicking the panel and selecting "Download CSV".
• Statistics Table: Added a statistics table below the histogram showing descriptive statistics (n, Mean, Std Dev, Min, Max), control limits (LCL, UCL), and process capability indices (Cp, Cpk, Pp, Ppk).
• Configurable Table Columns: Choose which columns to display in the statistics table via the panel editor.
• Multiple Custom Lines per Series: You can now add more than one custom control line to a single series.
• Gaussian Peak (µ) Control Line: New control line type that marks the peak of the fitted Gaussian curve. Uses the Levenberg-Marquardt fitted mean, which may differ from the arithmetic mean for non-normal data.
• Histogram Tooltip: Hover over histogram bins to see bucket range and count for each series, similar to Grafana's built-in histogram tooltip. Bell curve fitted values are included when a Gaussian curve is configured.
