Example gallery

Every example is a complete application in the examples/ directory. Build them with -DQACCELPLOT_BUILD_EXAMPLES=ON:

cmake -S . -B build -DCMAKE_BUILD_TYPE=Release -DQACCELPLOT_BUILD_EXAMPLES=ON
cmake --build build --config Release

Each executable is named after its example, for example QAccelPlotExampleVibrationMonitoring.

Showcases

  • Vibration Monitoring

    Vibration Monitoring

    Condition-monitoring dashboard: eight accelerometers streaming 2M samples into scrolling waveforms, RMS bars, a spectrum with a bearing-fault peak, and a spectrogram.

  • Performance Lab

    Performance Lab

    Stream up to 10M points, rectangles, or bars, or 100M heatmap cells, per tab and compare the cost of series count, ingestion API, and rendering options.

  • Quickstart

    Quickstart

    Minimal plot setup. Recipe: Basic static plot.

Plot types

  • Bar Chart

    Bar Chart

    Grouped monthly revenue with a horizontal toggle, profit bars colored against a target baseline, and animated updates. Recipe: Bar charts.

  • Histogram

    Histogram

    Sensor noise in equal bins, and request latencies in logarithmic bins or as density in one bin per axis tick. Recipe: Histograms.

  • Bands

    Bands

    Forecast with nested prediction intervals, and a rolling mean ± 2σ band over a simulated sensor signal. Recipe: Bands.

  • Error Bars

    Error Bars

    Calibration measurements with asymmetric errors, animated between samples, and error bars on grouped bars. Recipe: Error bars.

  • Step Lines

    Step Lines

    Hourly prices drawn with each step mode, and a live heater set point held as steps over the measured temperature.

  • Parametric Curves

    Parametric Curves

    Spiral, Lissajous figure, spirograph, and Van der Pol phase portrait: curves that loop and cross themselves.

  • Heatmap

    Heatmap

    Two-source wave interference on a 400 × 300 grid, keyed by a histogram of the cells in view, with colormap presets and an interactive color bar. Recipe: Heatmaps.

  • Point Cloud

    Point Cloud

    200K-point scatter colored by value, with a hover tooltip, rectangle zoom, and transitions between datasets. Recipe: Point clouds.

  • State Timeline

    State Timeline

    Two weeks of machine states in one RectangleSeries, colored by category, over full-height maintenance windows.

Styling

  • Line Styles

    Line Styles

    Dash patterns, line weights, and antialiasing. Recipe: Styling.

  • Markers

    Markers

    Every marker shape, filled and hollow; click one to draw a scatter plot with it.

  • Gradients

    Gradients

    Gradient area fills and strokes with presets, direction, and baseline.

  • Transitions

    Transitions

    Morph and draw animations between datasets.

  • Theming

    Theming

    Plot, axis, grid, legend, and series colors bound to the dark or light palette.

Axes

Data

  • Realtime

    Realtime

    Scrolling vibration signal in a 20-second window, updated every frame. Recipe: Real-time scrolling data.

  • Missing Data

    Missing Data

    NaN, ±Inf, and log-invalid data points drawn as gaps or connected.

  • Export

    Export

    Save a plot as PNG, JPEG, WebP, or TIFF at a chosen scale and background, or copy it to the clipboard. Recipe: Exporting images.
