mendix-vega-charts skillA
mendix-vega-charts is agent-read markdown (skill) from mendixlabs/mxcli: Chart a Mendix app with Vega-Lite through a pluggable widget that takes the specification and the data as separate properties, so the model emits rows and never assembles a chart payload. Use when a Mendix project needs charts Studio Pro's own widgets do not cover — small multiples, faceted tables, sparklines inside a data grid, calendar heatmaps, brushed scatter plots, stream graphs — or when an agent is authoring charts from MDL rather than by hand..
Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.
What the file says
# Vega-Lite charts in Mendix
## What this is
A pluggable widget, roughly 150 lines of TSX, with two properties that matter:
| Property | What it carries |
|---|---|
| `spec` | A Vega-Lite or Vega specification, as JSON text. Static, authored once, committed. |
| `chartData` | A string attribute holding a JSON array of row objects. Built by a microflow. |
The widget folds the data into the spec under the name given by `datasetName` and hands the result to `vega-embed`, which picks Vega or Vega-Lite from the spec's own `$schema`. Nothing else happens at runtime.
**The split is the whole point.** The model emits a table of facts; the specification decides what that table looks like. A microflow that concatenates a chart payload — series, axes, colours — is a microflow that has to be edited every time the chart changes, and it cannot be checked without running the app. A microflow that emits `[{"cat":"Groceries","m":"2026-06-01","v":697.70}, ...]` can be checked against the database with a SQL query, and the spec beside it can be compiled and measured without a browser at all (see [Verifying](#verifying-without-running-the-app)).

How to install
mdr add mendixlabs/mxcli/mendix-vega-charts@git:20260921.10d6892mdr add mendixlabs/mxcli/mendix-vega-charts@sha256:1e2ac69d2b843f6cPin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
