Graphs vs Kibana

Graphs is a free Linux desktop application for plotting and manipulating data, released under the GNU General Public License v3.0 or later. It imports column files such as CSV, DAT, XY, and plain text, plus ODS and XLSX spreadsheets, SQLite databases, Panalytical XRDML, Leybold XRY, and Graphs project files. Equations can generate datasets and remain rendered across the plot canvas. Data operations include translation, multiplication, normalization, centering, smoothing, differentiation, integration, Fourier transformation, combining, shifting, cutting, and custom coordinate transformations. Curve fitting offers linear, quadratic, exponential, power-law, logarithmic, sigmoid logistic, Gaussian, and custom-equation models. Results may include parameter confidence margins, confidence bands, R², RMSE, and residual plots. Users can select or create plot styles controlling colors, fonts, lines, markers, error bars, axes, ticks, and grids. Figures export to PNG, JPEG, WebP, SVG, PDF, PostScript, or Encapsulated PostScript, with underlying data export too. Vector output can be edited in applications such as Inkscape. Flathub describes the app as requesting no permissions.

Kibana is an open-source web interface for querying, analyzing, visualizing, and managing Elasticsearch data. Its tools include Discover, Dashboards, Dev Tools Console, Maps, alerting, and developer console capabilities. Interactive dashboards can combine metrics, XY charts, graphs, maps, tables, live data, drilldowns, and reusable saved queries, and dashboards can be embedded. Data sources include Elasticsearch, Elastic Agent, Logstash, Beats, OpenTelemetry, APIs, cloud platforms, files, logs, metrics, traces, and events. Data can be ingested into Elasticsearch through OpenTelemetry, Logstash, and Beats. The self-managed Free and open tier includes Kibana and the full Elastic Stack, with native authentication, role-based access control, and TLS encryption; its support is community-based. Elastic Cloud Hosted and Serverless offer a free trial. Standard hosted pricing is listed from $99 per month, as low as, based on cloud production configuration. Kibana also offers no-code machine learning for anomalies, rare events, message patterns, and alerting, plus geospatial tools such as distance filters and shape overlays.
