Why don't you just change the place of the marker?
You force the chart window to be 0 to 8 vertically, and then you place markers at 0 (so centered on 0 axis) and on 8 (so centered on 8 axis)

2 solutions: change axis range or move markers...

Dear all, Here is a short, but maybe tough, issue that I have: I am useing stepped charts, and in some cases, I would need to have a step drawned before the first point of my timeseries. Here is an example: I have the following time series: 1:00 ; 12 2:00 ; 10 3:00 ; 10 this creates steps from 1:00 ...

Thank you for the answer, that's what I was suspecting.
For the implementation, I found someone that posted this suggestion, which I'm going to try:

Indeed it is sometimes necessary to show the steps the other way than the usual...

Dear all, Here is my issue: I need to draw a stepped chart, but with the step being drawn before the point defined. For example if I have the following serie: (1,100),(2,50),(3,70),... I would need to have a step at "100" between 0 and 1, a step at 50 between 1 and 2, etc... I did not find a way to ...

you should have a look at financial charts demos.

Sorry I edited my post above. Added some data. I agree, I think that with all things considered Java should actually give us a performance boost. I am just a little unsure about how efficient JFreeChart's dynamic data is. I assume that it is quite efficient as it seems to be a solution selected by ...

en meme temps, vu le peu d'activite sur ce forum, si on commence a faire la tour de babel je crains le pire

(eh oui, j'ai change d'avis )

What I understand is that you wand to set the color for the whole serie... I am right? In that case this is a method of the renderer. example: XYItemRenderer renderer = plot.getRenderer(); renderer.setSeriesPaint(0,Color.GREEN); renderer.setSeriesPaint(1,Color.YELLOW); where 0 and 1 are the index of...

Do you mean something like CrosshairDemo2.java, but with the values displayed directly on the chart rather than in a table below the chart? That would need some custom code - either an new annotation type or a direct modification to the plot drawing code. Exactly! Could you please give me direction...

hmmm it looks like we're looking for the same thing.
will keep you informed if I find...

To summarise the answer is yes: you can have completely different X values for each serie of a dataset.

However, the result might not be nice if X values are too far from one dataset to the other...

consider using many different charts in that case.

I actually would like it to show just like a tooltip, but permanently and for all curves at the same time

hello all,

Here is my issue:

I have a chart with multiple curves.
I added a vertical crosshair on it, so that we can point multiple points at the same time.

How to print directly on the chart all points that have been designed? I'm pretty sure it's possible...

Thank you very much for your help.

there should be a property of the axis to set this.
Make a search on "tick units" and ValueAxis on the forum, you should find everything you need.

Sorry, I'm not a guru yet so I can only show the path
