Re: Plot by hand on scatter plot

Add a ChartMouseListener to your ChartPanel and examine the ChartEntity associated with the ChartMouseEvent.

Re: Add individual shapes to a series using XYLineShapeRenderer

Try returning an empty shape for the undesired points, e.g. ShapeUtilities.createUpTriangle(0).

Re: How To Partially Fill The Bars in BarChart

You might try a stacked bar chart; StackedBarChartDemo7 in the gallery looks relevant.

Re: Add individual shapes to a series using XYLineShapeRenderer

Add a ChartMouseListener; examine the ChartEntity subclass to determine which point(s) should return a different shape from your implementation of getItemShape().

Re: autoscale chart

You can control zooming and panning with the mouse, as suggested here, or by evoking the desired handlers, as suggested here.

Instead. ChartPanel::getToolTipText queries the relevant ChartEntity for you, so you can focus on formatting.

Re: Restricting ToolTipText to Chart Line Only

Apply an XYToolTipGenerator such as the StandardXYToolTipGenerator to your renderer, as shown in ChartFactory.createTimeSeriesChart(). Your implementation of generateToolTip() will have access to the relevant dataset, series and item.

Re: package org.jfree.data.general does not exist

If you're using JFreeChart 1.0.19, verify that both jfreechart-1.0.19.jar and jcommon-1.0.23.jar are in your class path when compiling.

Code: Select all

export JFREE_HOME=/jfreechart
javac -cp .:$JFREE_HOME/lib/* CreateChart.java …
If you're using JFreeChart 1.5, see Migration from JFreeChart 1.0.x.

Re: Add individual shapes to a series using XYLineShapeRenderer

Yes. Override the renderer's getItemShape() method. A typical example may be found here.

Nor should there be. The particular font used is an attribute of the view. In contrast, a dataset is a model of the data displayed by the view. The separation is intentional.

Re: Attempting to assign weaker access privileges error in ChartViewer class

NB: "When migrating from JFreeChart 1.0.x to JFreeChart 1.5.0…all the classes from JCommon that are used by JFreeChart have [been] integrated within the JFreeChart jar file within a different package than before (you will need to change your imports)."
