I have a JFree XY Line chart which always starts at x = 0. Then based on user defined settings from a properties file, the application increments based on that number (this represents the time in minutes).
For example, x = 0 to start the user defined setting is 5 so the scale goes 0, 5, 10, 15, 20…, or the user setting is 3 so it goes 0, 3, 6, 9, 12… Pretty simple.
The issue I am having is the way in which the graph starts. If I start at 0, then 0 is in the middle of the graph rather than at the bottom left with -0.0000005, -0.000004, -0.000003… 0.000000 , 0.000001 , 0.000002… 0.000005
How can I just manually add the scale at the bottom, i.e. define it should be increments of 2 and then maintain it?
You should use NumberAxis, which contains a lot of methods to define the scale of your chart.
Example :
// Create an XY Line chart
XYSeries series = new XYSeries("Random Data");
series.add(1.0, 500.2);
series.add(10.0, 694.1);
XYSeriesCollection data = new XYSeriesCollection(series);
JFreeChart chart = ChartFactory.createXYLineChart("XY Series Demo", "X", "Y", data,
PlotOrientation.VERTICAL,
true, true, false);
// Create an NumberAxis
NumberAxis xAxis = new NumberAxis();
xAxis.setTickUnit(new NumberTickUnit(2));
// Assign it to the chart
XYPlot plot = (XYPlot) chart.getPlot();
plot.setDomainAxis(xAxis);
Based on this example, here's an sscce that uses setTickUnit() to adjust the domain axis tick unit dynamically, starting from the value 5.

On an XYPlot, I want the coordinates of mouse displayed as hint near to mouse, but only when (the mouse) move on chart! In another words, when the crosshair moves to another point, the positioning of the coordinate values would move too, following the crosshair.
Also 1 horizontal line and 1 vertical line will be drawn, that intersects specifically at the point that mouse is over on.
Is this possible?
Until now I can get the coordinates and printed on console using ChartMouseListener and chartMouseMoved method.
This is my project and how I want to be the chart with mouse.
JFreeChart has quite flexible support for crosshairs. To do what you described I would use an Overlay on the ChartPanel, and update the crosshairs from your ChartMouseListener. Here is a self-contained example (which I'll add to the collection of demos that we ship with the JFreeChart Developer Guide):

I'm having some trouble while working on JFreeChart RingPlot. I've managed to put labels inside my chart, yet I can't change their positions as I want. Here where am I right now;
I need to move the labes closer to the edges of the chart so that I can lower the section depth and have a better ring look. So far, I tried to play with setSimpleLabelOffset and setLabelGap methods but didn't work well.
Here is my code;
DefaultPieDataset dataset = new DefaultPieDataset();
dataset.setValue("Critical", new Integer(5));
dataset.setValue("Important", new Integer(20));
dataset.setValue("Moderate", new Integer(19));
dataset.setValue("Low", new Integer(5));
JFreeChart chart = ChartFactory.createRingChart("", dataset, false, true, false);
RingPlot pie = (RingPlot) chart.getPlot();
pie.setBackgroundPaint(Color.WHITE);
pie.setOutlineVisible(false);
pie.setShadowPaint(null);
pie.setSimpleLabels(true);
pie.setLabelGenerator(new StandardPieSectionLabelGenerator("{1}"));
//pie.setSimpleLabelOffset(new RectangleInsets(1, 1, 1, 1));
//pie.setLabelGap(0.05);
//pie.setLabelPadding(new RectangleInsets(100, 5, 10, 5));
pie.setLabelBackgroundPaint(null);
pie.setLabelOutlinePaint(null);
pie.setLabelShadowPaint(null);
pie.setSectionDepth(0.50);
pie.setSectionOutlinesVisible(false);
pie.setSeparatorsVisible(false);
pie.setIgnoreZeroValues(true);
Any idea how may I achieve this?
Thanks in advance.
Edit: Thanks for the response #trashgod, but something is wrong with my environment iI guess. I copied and pasted the whole code you presented above and what I get is this:
The default RectangleInsets for PiePlot labels are inset relative to the plot's pieArea:
this.simpleLabelOffset = new RectangleInsets(UnitType.RELATIVE, 0.18, 0.18, 0.18, 0.18);
The example below cuts the insets in half and changes the section depth accordingly:
pie.setSimpleLabelOffset(new RectangleInsets(UnitType.RELATIVE, 0.09, 0.09, 0.09, 0.09));
pie.setSectionDepth(0.33);

I am using JFreeChart to make a barchart vs time. For some reason on these charts, the tick labels on the x axis turn into "..." occasionally. There seems like there is plenty of room for the labels to expand, but instead it just cuts off the whole thing. How can I fix this.
I tried uploading a picture using the image button, but it does not seem to be working.
Here is code with a similar set up to my project. Strangely it acted different then what is happening to my build. On mine instead of saying "Hou...", it just says "...". Ignore comments and all other uneeded things please.

Don't use a null layout; let the layout manager do the work. The default layout of JPanel is FlowLayout, which ignores your subsequent changes. In the example below,
The chartPanel is given a GridLayout; when added to the enclosing frame's CENTER, the chart will be free to grow as the frame is resized.
Avoid unnecessarily nested panels.
Use setExtendedState() to maximize the frame.
If necessary, use one of the approaches suggested here to alter the chart's initial size.
If you choose to alter a Font, use deriveFont() to avoid abrupt disparities in the user's chosen settings.

I'm a beginner in JFreeChart. I want to change the x axis values of this chart to milliseconds, with 5 ms intervals. I've tried
axis.setTickUnit(new DateTickUnit(DateTickUnitType.MILLISECOND, 5));
but I keep having a compilation error. I found somme suggestions in the net, but nothing worked for me. Also, is there any way to set a maximum value for the x axis, like 300 ms.

Some possibilities to consider:
Specify the units in the corresponding axis label when creating the chart.
"TIME (ms)", // range axis label
Use setDateFormatOverride() to change the format of the axis labels, e.g. three-digit values.
DateAxis axis = (DateAxis) plot.getRangeAxis();
axis.setDateFormatOverride(new SimpleDateFormat("SSS"));
Use setMaximumDate(), if warranted.
axis.setMaximumDate(new Date(300));
Suppose that we need to display multiple XYSeries in a single XYSeriesCollection. My problem is that every time I add a XYSeries, the JFreeChart wants to update the chart and that slows down the process of displaying multiple XYSeries.
What I want is similar to this:
// Do not update the chart
XYSeriesCollection.add(XYSeries1)
XYSeriesCollection.add(XYSeries2)
...
XYSeriesCollection.add(XYSeries10)
// Update the chart
How can I do this?
Construct a new XYSeriesCollection having the desired series, and invoke setDataset() on the XYPlot. This will generate a single DatasetChangeEvent.
Addendum: Here's an SSCCE that updates N series, each having N2 values. As this is a performance question, the example may be helpful in profiling.

Looking at the documentation for XYSeriesCollection (assuming add should be addSeries) there is no method addAll (or similar).
If you want, you could extend XYSeriesCollection and implement addAll. In this method, you could temporarily disable all listeners before adding and re-add them after. However, this would probably be a bad idea, and would definitely need to be synchronized:
it would produce unpredictable polymorphism behavior
it would require reflection hacks, as AbstractDataset.listenerList is private
it could generate a security exception
it would not be thread safe
So the short answer is no, it is not feasible.
… but this is a starting point for how you could do it:
Field field = getClass().getDeclaredField("listenerList");
field.setAccessible(true);
EventListenerList ell = field.get(this);
// go from here
field.setAccessible(false);
