Re: Change tool tip font
Thank you very much for your response. I tried to change the global UI font for the tooltips doing something like UIManager.put("ToolTip.font", new FontUIResource("SansSerif", Font.BOLD, 28)); but the tooltips remained unaffected. However, it seems that, when used within a JavaFX app, the JFreeChart...

Re: Crosshair lock doesn't work properly with multiple axes
Hello, First, I apologise for the (very) late response. You can see below a small sample runnable piece of code which shows the issue. If you try to click on the points of the blue line (which is related to the 2nd axis), for example on (1994, 25), you can see that the vertical axis crosshair points...

Get series index from the crosshair
Hi,
I was wondering if it is possible to get the series index (or key) of a data point which a crosshair points at (in the same way we can get its x, y values for example).
Any help is welcome!

Re: Slow performance with large TimeSeries Dataset
As you said, first I create the dataset and then I create the chart and add the dataset to it. The renderer is a simple XYLineAndShapeRenderer. However, I will consider your suggestion about the DefaultXYDataset.
Thanks a lot!

Re: Slow performance with large TimeSeries Dataset
Thanks for your reply.
You were right, I was retrieving the data from a database which created the additional delay. Now this is fixed and plots up to 5E4 data points are generated fast, I've noticed however that beyond that the delay (around 10 sec) is inevitable, which I suppose is expected (?).

Slow performance with large TimeSeries Dataset
Hello, I'm trying to plot a relatively large TimeSeries data set (about 2000 data points) and it takes almost 1 minute to plot! I changed the renderer from XYLineAndShapeRenderer to SamplingXYLineRenderer but it made no difference. I also tried to add data and create the data set before I create the...

Re: Dashed lines don't appear when using ChartViewer
Thanks for the quick response!
You are right I was using the FXGraphics2D.java from release 1.0.19 (didn't know about the updates...). After updating it with the new code it works fine!

Re: Slow chart functionalities and dashed lines don't appear
Thanks a lot for your reply! I managed to solve my performance issue. As far as the dashed lines problem, I wrote that as saved jpeg image, the dashed lines of my JFreeChart appear as they should. The problem is when the chart is drawn and appeared within a ChartViewer in my application (I use JavaF...

Dashed lines don't appear when using ChartViewer
Hello, I am using JFreeChart with JavaFX. For the needs of my application I have to redraw the whole chart several times. At the first time, all chart functions (zooming, panning, etc.) perform pretty well. However, after several times of redrawing, these functionalities become very sluggish. Keep i...

Crosshair lock doesn't work properly with multiple axes
Hello, I'm using JFreeChart 1.0.19 and I want to lock the crosshair on data points even when I have multiple vertical axes. However, when I click on a series bound to the secondary axis the crosshair points to the corresponding value of the primary axis which is annoying! Do you have any idea how th...

Multiple fonts in the same chart title or axis label
Hello, I've been trying to use am HTML wrapped string (e.g. "<html><b>Time</b> (seconds)</html>") but it seems that JFreeChart methods for setting text to chart labels (e.g. "setLabel") do not "understand" the html wrapping. Do you have any idea how I could implement this (I want generally to apply ...

Re: Single axis zoom property disabling in a multi-axis char
Thanks a lot paradoxoff! Your answer was helpful.
It would be nice though to have this feature integrated so that axes can be easily zoomed in and out individually and not in blocks of either range or domain axes.
