ApexCharts vs silx: at a glance
What is ApexCharts?
Three releases in three weeks moved ApexCharts from free library to gated open-core.
ApexCharts is shipping the v6 line at an unusual clip — ten releases since 20 July, spanning a plugin platform, a hybrid SVG/canvas renderer, and two new chart types. The core is still zero-dependency and SVG-first, and every release states that existing configs render unchanged. What is new is a commercial layer: an offline licence check now sits over seven premium modules and one chart type, while the free catalogue keeps expanding alongside it.
What is silx?
silx 3.0 moved its default Qt binding to PySide6 — a migration for everyone embedding it.
silx releases a couple of times a year and reached 3.0.0 in April 2026, which raised the Python floor to 3.10 and switched the default Qt binding to PySide6. The same release reworked the viewer's data views: 3D scatter support, dedicated RGB(A) image views, the composite ImageView split into Plot2dView and ComplexImageView, and NXdata stacks displayed as images. 3.1.0 has since added asinh axis scaling, the twilight colormaps, and dark-theme icons.

ApexCharts
10.0ANALYTICS
Three releases in three weeks moved ApexCharts from free library to gated open-core.
◆ Current state
ApexCharts is shipping the v6 line at an unusual clip — ten releases since 20 July, spanning a plugin platform, a hybrid SVG/canvas renderer, and two new chart types. The core is still zero-dependency and SVG-first, and every release states that existing configs render unchanged. What is new is a commercial layer: an offline licence check now sits over seven premium modules and one chart type, while the free catalogue keeps expanding alongside it.
◆ Where it's heading
The commercialisation arc tightens one notch per release. 6.5.0 introduced licensing with a watermark and an explicit promise that no chart type would be gated; 6.6.0 gated one; 6.7.0 changed enforcement from accepting any valid key to requiring an entitled plan. Running underneath is a genuine engineering push — incremental updateSeries, canvas cell rendering, a numeric fast path for line and area — that makes the paid layer easier to justify. The pattern is a generous free core with the new authoring and analysis surface behind a key.
◆ Prediction
Expect more premium chart types following `unit`, since the gating machinery and trial-mode watermark are now built and proven. The shared key format across the apex* family suggests entitlement checks propagate to the sibling libraries next.
silx
2.5ANALYTICS
silx 3.0 moved its default Qt binding to PySide6 — a migration for everyone embedding it.
◆ Current state
silx releases a couple of times a year and reached 3.0.0 in April 2026, which raised the Python floor to 3.10 and switched the default Qt binding to PySide6. The same release reworked the viewer's data views: 3D scatter support, dedicated RGB(A) image views, the composite ImageView split into Plot2dView and ComplexImageView, and NXdata stacks displayed as images. 3.1.0 has since added asinh axis scaling, the twilight colormaps, and dark-theme icons.
◆ Where it's heading
The project is doing a generational refresh of its GUI layer: modern Qt binding, modules broken out of the composite widgets that had accumulated responsibilities, and the theming work that a desktop application needs to look current. Underneath, the recurring fixes are about HDF5 behavior in real facility environments — file locking, NFS refresh, Windows display paths — which is where a synchrotron toolkit actually gets stressed. Feature growth is concentrated in silx view rather than the library API.
◆ Prediction
Expect the 3.1.x line to keep filling in plotting options and theming, with the PySide6 default flushing out binding-specific bugs from downstream applications over the next few releases.
