What is afcharts?

UK government chart styling in ggplot2, chasing ggplot2 v4 and stretching its palette to five.

afcharts supplies the UK Analysis Function's chart styling for ggplot2, as a theme, colour and fill scales, and a use_afcharts() call that applies the styling globally. Version 0.5.1 extends the sequential palette to five shades so it can carry quintile data such as deprivation bands, renames the na_colour argument to na.value, and adds a reset argument to switch the styling back off. The package began as a first release derived from sgplot and has had three releases in roughly two years.

What is SigNoz?

Search without knowing the field — SigNoz keeps lowering the cost of not knowing your schema

SigNoz is an OpenTelemetry-native observability platform, and its recent quarter runs on two threads: compatibility as a migration argument, and agent-readiness. The dashboard rebuild on the CNCF Perses specification was the clearest statement of the second. The newest release adds a search() function to the Logs Explorer that matches a literal, case-insensitive term across body, attribute and resource keys and values without the user knowing which field holds it, optionally narrowed to named field contexts.

UK government chart styling in ggplot2, chasing ggplot2 v4 and stretching its palette to five.

◆ Current state

afcharts supplies the UK Analysis Function's chart styling for ggplot2, as a theme, colour and fill scales, and a use_afcharts() call that applies the styling globally. Version 0.5.1 extends the sequential palette to five shades so it can carry quintile data such as deprivation bands, renames the na_colour argument to na.value, and adds a reset argument to switch the styling back off. The package began as a first release derived from sgplot and has had three releases in roughly two years.

◆ Where it's heading

The work splits between palette design and keeping the styling composable. On the design side the sequential palette growing to five shades is driven by a specific reporting need rather than aesthetics, since quintiles are a standard unit in UK official statistics. On the mechanical side, the na.value rename was forced by ggplot2 v4.0.1, theme_af() now respects options set by an earlier use_afcharts() call, and a reset argument acknowledges that global styling needs an off switch. These are the problems a styling package hits once people use it inside larger documents.

◆ Prediction

Expect continued adjustment to ggplot2 v4, since the na.value rename is unlikely to be the only argument affected, and further palette work driven by the reporting formats government analysts actually publish. As a sibling to aftables in the same Analysis Function family, it is likely to keep tracking that guidance rather than setting its own direction.

Search without knowing the field — SigNoz keeps lowering the cost of not knowing your schema

◆ Current state

SigNoz is an OpenTelemetry-native observability platform, and its recent quarter runs on two threads: compatibility as a migration argument, and agent-readiness. The dashboard rebuild on the CNCF Perses specification was the clearest statement of the second. The newest release adds a search() function to the Logs Explorer that matches a literal, case-insensitive term across body, attribute and resource keys and values without the user knowing which field holds it, optionally narrowed to named field contexts.

◆ Where it's heading

Both threads keep advancing. PromQL conformance and an open dashboard schema lower the cost of moving to SigNoz from whatever is already installed; full-text search lowers the cost of not yet knowing your own telemetry schema, which is the same argument aimed at a new user's first hour rather than at a migration. Integration onboarding keeps expanding at a weekly clip, and the v1 alert history endpoints are running against an announced deadline.

◆ Prediction

Expect the schema-first treatment to reach alerts and saved views next, and the v1 alert history endpoints to disappear within a release or two; since search()'s own notes steer users toward field filters once the schema is known, field-context narrowing is the likely place it gets faster.
