Help with one axis chart and callouts in JavaFX

[ad5xj]

I am creating a chart that displays occurrences of data, each of which I wish to mark with a callout having some detail for each point.

A small example would be a chart of limited-range frequencies, with data occurrences charted at points along the same vertical axis, each point marked by a callout providing detail for each.

I understand that this is probably an unconventional way to display data since only the vertical axis is needed here and all data points are on the same vertical axis.

Problem #1 how do I create the chart with only the vertical axis scale?

Problem #2 how do I create the callout for each charted point?

Problem #3 is there a way to associate the charted point with the callout detail in such a way that I can connect them with a drawn line (per the conventional callout display)?

Having asked this question on stackoverflow.com, I was directed here by one mentor.
This is my first foray into charting graphics with JavaFX and jFreeChartFX so this may be a newbie question. Any help would be appreciated.

As suggested here, you might want to look at org.jfree.chart.annotations and try a few examples; also look a tooltips and axis visibility. Most examples can be easily adapted to JFreeChart-FX.

This suggestion does not get me past two of the three problems. I don't think annotations provide the whole answer. The examples were available before I posted this message. There were no clear examples that provided any ideas for me.

Thank you for trying.

In addition to tooltips and axis visibility, look at org.jfree.chart.labels.

This crude diagram I created manually, is what I wish to achieve. If there are helpful hints as to how this can be done, I am very appreciative.

These look like pointer annotations. Browse the sample demo and look here for specific examples.
