SlintPlot 0.5.1

Added

• integer-ticks on line, bar, horizontal bar, scatter, bubble and time
  series charts: the value axes step by at least 1. For values that are
  counted, such as people or items, where a short range otherwise gets
  ticks at 0.5 or 0.2: a largest value of 3 gives 0, 1, 2, 3. Off by
  default; a scale that already steps by 1 or more is unchanged.

Fixed

• Stacked bars with a bar-radius are rounded at the ends of the whole
  stack only, so a stack reads as one bar: every segment used to be rounded
  on all four corners, which left notches between them. A zero value or a
  hidden dataset at the end of a stack passes the rounding on to the
  segment next to it, and stacks above and below zero are square where they
  meet. Bars side by side are rounded as before.
• The legend's swatches are filled with the chart's own fill-opacity, on
  bar, line, horizontal bar, candlestick and waterfall charts: they used the
  theme's, so a chart with solid bars had pale swatches.

Website

• The blog's front page shows the picture of each post.

Example apps

• Gallery: the segmented ring and tile grid samples with four charts show
  one at a time, picked above the chart, on phones and small windows, where
  four were too small to read. The code button shows the code of the chart
  shown.

Gallery and stress apps 0.5.1

The example apps for SlintPlot 0.5.1, built with the new library:

• slintplot-gallery: a sample browser with every chart type, a theme picker, dark mode, and buttons to randomize, add and remove data. New: the segmented ring and tile grid samples with four charts show one at a time, picked above the chart, on phones and in small windows, where four were too small to read; the code button shows the code of the chart shown. Clicking a chart shows what was clicked. The code button opens each sample as a small app that runs as it is. slintplot-gallery --snapshot <dir> renders every sample to PNG.
• slintplot-stress: streams up to 8 datasets at 10 to 100,000 samples a second into a window of 1,000 to 10,000,000 values or everything received, with zoom and live frame times. slintplot-stress --bench prints headless timings with the software renderer, and --bench-gpu times the same charts with Skia on the GPU.

Both apps draw with Slint's FemtoVG renderer by default; start them with SLINT_BACKEND=winit-software for the software renderer. Built with --features skia, they also run with SLINT_BACKEND=winit-skia. See Choosing a renderer.

What's new in the library: see the 0.5.1 release. Stacked bars with a bar-radius are rounded at the ends of each stack only, the legend's swatches have the chart's own fill-opacity, and integer-ticks keeps the value axis in whole numbers for counted values.

SlintPlot 0.5.0

Added

• legend-attached on pie, doughnut, polar area, radar, radial bar,
  sunburst, segmented ring and tile grid charts, on by default: the legend
  stays next to the chart instead of at the edge of its area, which was far
  away when the area was much taller or wider than the round or square
  chart in it. false keeps it at the edge, as before.

Changed

• The focus ring round a chart shows only when the keyboard brought the
  focus (Tab) or has been used since, not after a click, as :focus-visible
  on the web. Clicking still gives the chart the arrow keys.

Example apps

• Gallery: the line chart with and without points, the pie chart with
  and without data labels, and the radar chart with lines and filled are one
  sidebar entry each, with a tab per variant; the filled radar chart moves
  from Area charts to the radar chart.
• Stress test: --bench-gpu [dir] times the same charts as --bench
  with a GPU renderer, Skia on macOS, drawing each frame with
  Window::take_snapshot so that the GPU's work is included; with a folder,
  it saves every frame as a PNG.
• Both apps: a skia feature builds them with Slint's Skia renderer, to
  run with SLINT_BACKEND=winit-skia.

Tested

• Skia: every gallery sample draws correctly with Slint's Skia renderer on
  macOS, Linux and Windows, as with FemtoVG and the software renderer.

Documentation

• A compatibility box next to Getting started: Rust only, the Slint and
  Rust versions, the platforms and renderers tested, and no live preview.
• Performance: how many points or items each chart can show at 60 fps,
  30 fps and within a second, with the software renderer and with Skia, and
  why the numbers look as they do. The full results moved to a new
  benchmarks page, measured again with SlintPlot 0.5.0 and Slint 1.18.1, with
  Skia's numbers and how to repeat them.
• How to choose a renderer for the example apps.

SlintPlot 0.4.3

Fixed

• FunnelChart: on Linux, Windows and in browsers, where Slint draws with
  femtovg, every stage was drawn a pixel larger all round, so the gap
  between stages was about half of gap, with a stray line at its ends.
  The stages are now drawn counterclockwise and back to their start, as the
  other charts' shapes since 0.4.2, and a test checks that Slint takes them
  as solid.

SlintPlot 0.4.2

Fixed

• SegmentedRingChart, TileGridChart, and the slices and rings of pie,
  doughnut, polar area, radial bar, gauge and sunburst charts: on Linux,
  Windows and in browsers, where Slint draws with femtovg, some cells merged
  into solid bands and gaps closed, on one half of a segmented ring chart and
  in every tile grid. Slint's femtovg renderer works out from a shape's
  points whether it is solid or a hole, leaving out the closing edge, so the
  answer depended on where the shape was; it draws a hole's smoothed edge a
  pixel outside it. Every shape is now drawn counterclockwise and back to its
  start, which Slint takes as solid wherever it is.

SlintPlot 0.4.1

Fixed

• SegmentedRingChart: the gaps between segments are as wide in every ring,
  with parallel sides, and at least 2px. They were a share of each segment's
  angle, so they widened outwards and, on screens of 1 pixel per point such
  as most Linux desktops and browsers, looked uneven where they were under 2
  pixels. segment-gap is now a share of a segment of the inner ring.

SlintPlot 0.4.0

Added

• SegmentedRingChart: a heatmap bent into concentric rings. values is a
  matrix ([[float]]), one row per ring, the first outermost, and one
  segment per column, going round from start-angle, either way. The matrix
  sets the size: as many rings as rows and as many segments as the longest
  row, so data of any shape fits without settings; shorter rows and missing
  values (NaN) are left as a faint track. Cells are colored on a scale, as in
  HeatmapChart (color, diverging, fixed-range), with a color scale
  legend, or by category: with classes set, each value is a category index,
  and the categories make a legend that hides them. x-labels go round the
  outside, thinned where they don't fit, and y-labels name the rings in the
  tooltip. center-text and center-label are written in the middle, and
  hovering a cell shows it there instead. A dot can mark the start, and
  glow adds a soft light in the middle. The cells sweep in when the chart
  appears; the arrow keys go round and between the rings, and
  cell-clicked(row, column) reports clicks.

• TileGridChart: a matrix as rows of rounded squares, one per value, like
  an activity grid. It takes its data as SegmentedRingChart does: values
  is a matrix ([[float]]), one row of tiles per row, and the matrix sets the
  size, the tiles staying square, as large as fit, and centered. Cells are
  colored on a scale or by category (classes), with the same properties; missing
  values are empty tiles, a faint track. y-labels go at the left and
  x-labels below, thinned where they don't fit; tile-gap and
  tile-radius shape the tiles. The tiles sweep in from the left; hovering
  outlines a tile with a tooltip, the arrow keys move from tile to tile, and
  cell-clicked(row, column) reports clicks.

Example apps

• Gallery: builds without Slint's binding loop warnings. The window
  shrinks to phone width, so a browser window made narrower switches to the
  phone layout instead of cutting off the page; the layout switches at 900px
  instead of 720px, where the sample list and header no longer fit beside the
  chart.
  Samples of the two new charts under Heatmaps, each one sidebar entry with
  two tabs, by category and on a scale, of four charts of different sizes and
  uses. They follow the theme, with their own colors only where the colors
  carry meaning, such as green, amber and red for a service's status; on the
  segmented ring category page and both tile grid pages, a second dropdown
  under the theme picker switches between the theme's colors and these. The heatmap sample shows
  the visits in each cell, in two-hour blocks so that the numbers fit.
• Stress test: segmented ring and tile grid charts, on a scale and by
  category, from 100 to 1,000,000 cells.
• Fuzz test: the two new charts, for 25 chart types.

Gallery and stress apps 0.4.3

The example apps for SlintPlot 0.4.3, built with the new library:

• slintplot-gallery: a sample browser with every chart type, including the new segmented ring and tile grid charts, in tabs by category and on a scale; a theme picker, dark mode, and buttons to randomize, add and remove data. Clicking a chart shows what was clicked. The code button opens each sample as a small app that runs as it is, in tabs: ui/app.slint with the chart's data, src/main.rs, build.rs, Cargo.toml and how to run it. In the Gantt sample, clicking a task opens a dialog that edits it. slintplot-gallery --snapshot <dir> renders every sample to PNG.
• slintplot-stress: streams up to 8 datasets at 10 to 100,000 samples a second into a window of 1,000 to 10,000,000 values or everything received, with line, bar, time series and scatter charts and more, with zoom and live frame times. slintplot-stress --bench prints headless timings.

What's new in the library: funnel stages keep their gaps on Linux, Windows and in the browser, as the segmented ring, tile grid and radial charts do since 0.4.2. See the 0.4.3 release; the 0.4.0 release added the segmented ring and tile grid charts.
