Data sources which are added/removed using the Plot.add() or Plot.remove() methods don't get the default renderers in XYPlot. They are also not shown on/removed from the legend.

If a data source gets added after creating a plot its columns don't get mapped at all and the data source isn't displayed anymore.

Currently, it is only possible to receive general change events from data sources. This may require additional filtering taking place at different listeners.

To avoid redundant calls, the respective data sources should invoke more specific methods depending on the type of the data change. Adding data for example could invoke dataAdded, while changing an existing value would call dataUpdated.

At the moment there's no way to assign data sources to certain axes (e.g. secondary axes in XYPlot). There should be a method, method parameter or flag to tell which which dimension (i.e. column in a data source) should be mapped which axis.

At the moment pie plots can't display a legend. This is caused by the current architecture: legends can't display a name for values, but only for the different data sources assigned to the plot.

Two steps are necessary to implement this feature:

1. A way to store labels for data values has to be found. This could be done by storing an additional column with labels in the data source, or by just using the data column as labels in the legend.

2. A custom implementation of legend has to be added to pie plot that will display the labels.

The current build fails on Mac OS X because it assumes that a Sun/Oracle? JDK is in use.

The attached patch alters the build in the following ways:

• add a macosx profile which targets the Apple JDK (use classes.jar instead of rt.jar);
• move the proguard phase into a profile; and
• attach sources and apidocs by default.

so to get a compressed/obfuscated build you would need to do

$ mvn -Pproguard package

and to get the same on a Mac OS X system

$ mvn -Pmacosx,proguard package

A new way for configuring plots should be added:
Additionally to adjusting the settings for each element there shuld be a way to pass a single Map which contains the visual properties for the plot. This would be a kind of stylesheet and could be shared across several plots.

At the moment data values can be displayed in plots like XYPlot or BarPlot. However, sometimes it may be desirable to display other values or labels next to the data points.

A new setting for a label column should be added to point renderers.

For text labels a way for storing texts must be found (see #49).

BitmapWriter.write(Drawable, OutputStream, double, double, double, double) creates a BufferedImage, retrieves a Graphics2D from it and draws the Drawable into the image. However, there is currently no way of setting rendering hints for the Graphics2D, so all drawables will be aliased.

Thanks to rpet for his error report that disclosed this issue.

The plot in exported bitmap images is of size 0 when the plot hasn't been sized before writing. The bitmap image itself has correct size but all elements of the the plot are located at (0,0).

It should be possible to display large sets of data, e.g. over 100,000 data points. At the moment all data is loaded into memory. The data that is loaded to memory and that is displayed will have to be reduced.

One possibility is to query ranges. Changes the data source interface may be necessary.

The axis isn't shown anymore after changing the axis renderer on a plot which is already displayed.

The current implementation of the Statistics class is very inefficient. When populating a DataTable by adding rows one by one, the whole statistics data is erased and recalculated. This is especially an issue when dealing with larger data sets, like the ScatterPlot example does.

At the moment DataSource is restricted to types that are derived from Number, which is sufficient in most cases. However, GRAL should be able to handle more diverse data in future.

Advantages:

• Ability to store strings for labels, etc.
• Improved handling of diverse data from external data sources, e.g. CSV files, or databases accessed via JDBC.

Disadvantages:

• Output of DataSource.get(int,int) method will get more difficult to use, i.e. casting will be necessary.

• Sorting of columns may get difficult.

When trying to zoom in or out of the plot in the MemoryUsage example, the next data update causes the zoom to reset. The user can only see some flicker and nothing changed. The same occurs when trying to scroll in any direction.

To circumvent this, I suggest:

• Disabling the scrolling, since the plot auto scrolls

• Fix the zoom issue

Problem: Calling method 'equals' causes a nullpointerexception in case 'old' hasn't been set before and therefore being null.

@SuppressWarnings("unchecked")
public <T> Comparable<T> set(int col, int row, Comparable<T> value) {
    Comparable<T> old;
    DataChangeEvent event = null;
    synchronized (this) {
        old = (Comparable<T>) get(col, row);
        if (!old.equals(value)) {
            rows.get(row)[col] = value;
            event = new DataChangeEvent(this, col, row, old, value);
        }
    }
    if (event != null) {
        notifyDataUpdated(event);
    }
    return old;
}

Solution:

@SuppressWarnings("unchecked")
public <T> Comparable<T> set(int col, int row, Comparable<T> value) {
    Comparable<T> old;
    DataChangeEvent event = null;
    synchronized (this) {
        old = (Comparable<T>) get(col, row);
        if (old == null || !old.equals(value)) {
            rows.get(row)[col] = value;
            event = new DataChangeEvent(this, col, row, old, value);
        }
    }
    if (event != null) {
        notifyDataUpdated(event);
    }
    return old;
}

Creating a plot without data sources causes a NullPointerException because the minimum and maximum values for each axis return null.

The key constant SIZE_COLUMN isn't public and thus cannot be used. It should be made public.

XYPlot provides constants for secondary axes (XYPlot.AXIS_X2 and XYPlot.AXIS_Y2) but currently adding doesn't work correctly. The plot will display the axis but only on top left of the plot graphics.

The behavior is reproducible using the following code:

Axis y2 = new Axis(0, 24);
plot.setAxis(XYPlot.AXIS_Y2, y2);
LinearRenderer2D renderer = new LinearRenderer2D();
plot.setAxisRenderer(XYPlot.AXIS_Y2, renderer);

Support for secondary axis should be added
