I have been working with JFreeChart for more than a decade, and picked up a thing or two along the way.
If you are unsure about what a property does, just play around, change it, and see in what way it affects the output.

I just checked the sourceforge-patch page. It contains three zip files, one incomplete with 6 files, and the other ones complete with 10 files. The most recent one (from january 28th, 2017) is complete, and also contains the multiline-label-feature.

In this thread, I have posted a code example. RUn that and move the mouse over the range annotation labelled "Range interval" that goes from 50 to 100 along the y axis. You should see a tool tip. The text can be changed by usingh a different string as parameter for the setToolTipText-method.

You need to include all files from the ZIP file that you get from the patch on sourceforge.

Not with a marker, but an annotation should do the job, at least if the plot is an XYPlot. See here. The annotations described in the linked thread support tool tips and entities, which is a prerequisite for some interactivity.

Unfortunately, I have no access to your C: drive, so I cannot see the image.

Both issues can be resolved by using a custom annotation. Here is a link to a forum thread with a description of some annotation classes that behave similarly to markers but offer more features.

// DOES NOT WORK double time = System.currentTimeMillis(); series[0].add(0, -0.3, 0.3, time, time - 150000, time + 150000); return dataset; Here you are saying that the range of x values goes from -0.3 to 3, but your x Axis is a DateAxis. You need to revert the x and y coordinates: series[0].add(ti...

Your question is independent on JFreeChart. It it is about replacements for PdfGraphcis2D, and PdfContentByte, and in more general sense about how to integrate instance of java.awt.Image into a PDF.

itext has undergone a complete API change between version 5 and 7. I suggest to contact itext directly.

Alternatively, you can write a custom CategoryAnnotation that is doing the job. IN this way, you do not have to change the source code of JFreeChart. Some time ago, I have written a set of annotations that can serve as marker replacements. Here is a link to the forum thread , where you will find a l...

The VectorRenderer draw arrows from x,y to x+dx, y+dy. The major issue that I see is that the renderer does the conversion from data space (the dx and dy values) to Java 2D space (the length with which the lines are drawn in the chart) by the domain and range axis. Since the axes represent time, and...

If I don't use the 3D BarRenderer, is it possible to change the width of the markers that it has the same width like the areas without marker? A CategoryMarker will either be drawn as a line or as a rectangle, depending on the return value of getDrawAsLine(). The rectangle will cover the entire spa...

I can't say that I have understood exactly what is wrong. I assume that the medium gray areas, that can hardly be distinguished from the plot walls, are the markers? I checked the code for BarRenderer3D, and this renderer doesnot override drawDomainMarker (which it should). I can only advice to have...
