Hi,
it seems that there is an increasing rate of meaningless posts (very general topic, such as "need help" or "I have a question", and no more than 1-2 sentences with very general content). Is it ok to treat those posts as spam, and delete them together with the user?

How to get input from a user is certainly not a JFreeChart specific question. How do you want to getthe input? gui, web, input prompt at the console,...?

That could be a bug in how JFreeChart handles the panning. When the mouse is moved up, the axis range is shifted to lower values, which, for an inverted axis, means that the plot is moving down. I wil have a look at that issue and see whether I can provide a patch. Which version of JFreeChart are yo...

How is your chart currently looking, and how would you like to to look?

Its hard to understand what you are really asking. I guess that you need to call

I would rather look at the code and see whether you have too many dataset or other changes going on.

I can't see the image. But the idea of overwriting drawItem sounds ok. You could use most of the existing code. In addition, you need to check whether the series that is currently being drawn is the last series that the plot has, and if so, call drawItemLabel multiple times using all available serie...

Call on the axis in question. Both XYPlot and CategoryPlot have this method implemented.

I assume that your x axis is a NumberAxis. Call

If you want to quickly plot a large number of data points as a line chart, look at the SmaplingXYLineRenderer.

Use the XYSeries constructor that accepts a boolean parameter and set that to "false".

During rendering, an XYDrawableAnnotation simply adds an instance of XYAnnotationEntity to the list of entities stored in the ChartRenderingInfo which is the parent of PlotRenderingInfo instance that is used ass parameter for the addEntity-method. The XYAnnotationEntity just contains a shape, a rend...

if you need to show the street names in a particular order, then simply add the the categories in the same order. For example:
dataset.addValue(speedForBrown, "Speed", "Brown");
dataset.addValue(speedForAsh, "Speed", "Ash");
and so on.

One of your problems seems to be the category order that you see in a CategoryPlot. In short: the categories are not ordered by default. The categories should appear along the CategoryAxis in the order in which the categories were added to the dataset, regardless of the type of Comparable. In the ab...
