JavaFxDataviewer is an open-source data visualization tool for JavaFX.

It is a JavaFX wrapper of the Dataviewer project : https://github.com/jasrodis/dataviewer. It is based on Plotly.js, JavaFx, Jetty and Websockets.

Examples

DataViewer & DataViewerConfiguration

DataViewer is the main plotting window. It is configured by the DataViewerConfiguration.

With DataViewer you can :

1. Update your Plot Configuration
2. Update your Plot Data
3. Reset your Plot Data
4. Get the exposed URL

DataViewer

    updatePlot(PlotData data);                               // Updates the plot
    updatePlotConfiguration(DataViewerConfiguration config); // Updates the dataviewer (window) configuration.
    getUniqueID(); // Get the unique ID of the dataviewer -  // navigate http://localhost:8090/view/UNIQUE_ID/

DataViewerConfiguration

    setPlotTitle(String title);              // plot title
    setxAxisTitle(String title);             // x axis title
    setyAxisTitle(String title);             // x axis title
    setMarginTop(int margin);               // margin top
    setMarginBottom(int margin);            // margin bottom
    setMarginRight(int margin);             // margin right
    setMarginLeft(int margin);              // margin left
    setPadding(int padding);                // padding
    setxRange(double min, double max);     // Set the range of the x axis of the dataviewer
    setyRange(double min, double max);     // Set the range of the x axis of the dataviewer
    setxAxisType(AxisType type);             // Set the axis type of x axis (log or linear)
    setyAxisType(AxisType type);             // Set the axis type of y axis (log or linear)
    showLegend(boolean set);                // Show/hide Legend
    setLegendInsidePlot(boolean inside);    // Show legend inside plot

See usage example below:

    // Create dataviewer
    DataViewer dataviewer = new DataViewer();

    // Create dataviewer configuration
    DataViewerConfiguration config = new DataViewerConfiguration();
    // Plot title
    config.setPlotTitle("Line Trace Example");
    // X axis title
    config.setxAxisTitle("X Example 1");
    // Y axis title
    config.setyAxisTitle("Y Example 1");

    // Update the configuration
    dataviewer.sendConfiguration(config);

    // Container of traces
    PlotData plotData = new PlotData(new LineTrace<Float>());

    // Plot all traces in the container.
    dataviewer.updatePlot(plotData);

Resetting the dataviewer example:

    JavaFxDataViewer dataviewer = new JavaFxDataViewer();
    DataViewerConfiguration config = new DataViewerConfiguration();
    dataviewer.sendConfiguration(config);
    PlotData plotData = new PlotData();
    dataviewer.updatePlot(plotData);

    // Reset your Plot (removes all trace from the dataviewer)
    dataviewer.resetPlot();

Traces

Traces are the different kind of plots that are going to be drawed in the DataViewer. Provided Traces:

• GenericTrace<T>
• LineTrace<T>
• ScatterTrace<T>
• BarTrace<T>
• TimeSeriesTrace<T>
• HistogramTrace<T>
• ContourTrace<T>

More to be provided..

GenericTrace

GenericTrace is an abstract class that all traces inherit from.

It can be used as a container when the type of the trace is not known.

See usage example below:

    Methods:
    // Config
    setTraceName(String traceName);                          // Updates the plot
    setConfiguration(TraceConfiguration traceConfig)         // Set the trace configuration
    setTraceColour(TraceColour colour);                      // Set trace Colour
    setTraceMode(TraceMode mode);                            // Set the trace mode (LINES, MARKERS, MARKERS_AND_LINES)
    setTraceType(TraceType traceType);                       // Set the trace Type (BAR, LINE, SCATTER, CONTOUR ...)
    setTraceVisibility(TraceVisibility visibility);          // Visibility of the trace(TRUE, FALSE, LEGENDONLY)

    // Data
    setxAxis(T[] xAxis);
    setyAxis(T[] xAxis);
    setzAxis(T[] zAxis);

GenericTrace Example - abstract class ( should not be used like this! )

    genericTrace.setTraceColour(TraceColour.PURPLE);
    genericTrace.setTraceName("Line Trace");
