I've been away for awhile so I haven't seen these more recent posts.... I develop code in an environment that does not have access to the internet, so it is problematic for me to add code examples in this forum. Given the amount of code involved for this solution, it would be rather time consuming t...

I've worked with item labels.

As far as I've been able to determine, you have to deal with possible overlap yourself.

Sounds like it might be a problem with the choice of layout manager. Also.... When you do successive actions to add things to the jPanelMain, do you clear out any old components before adding the new one? It is possible, depending on the layout manager, that if older components are not removed first...

Replies: 6

If you need to keep the legend on the bottom, then one way to accomplish your goal is to make each legend item long enough so that only one item fits on a single line. The legends are ordered left-to-right, as many as fit on a line before wrapping to the next line. If you add even more length to you...

Actually, I was faced with the same problem as you, but I also had to deal with the possibility of up to 20 series. I resolved it by doing two things: 1. I decided to keep the legend short, and moved it to the right side. 2. I put the chart in a tabbed pane, then in a second tab, I provided a table ...

As far as saving an instance of TimeZone.getDefault.... This shouldn't create a problem in most applications, but if you are in an application where the user can choose their time zone on the fly (as is the case with the application I work on), it could be a bad thing to have various time zone insta...

The Java Date class IS immutable. Where did you get the idea it isn't? Edited: after the subsequent post, am I missing something? Edited still later: I went back and double-checked the Java doc on Date. The Date class is not immutable as you've stated. Now, where did *I* get the idea that it was imm...

Use the following code to change the positioning of the legend from the bottom to the right side (or you could do the LEFT side). This has the effect of ordering the legend items in a vertical rather than a horizontal alignment. To my knowledge, you can't leave the legend on the bottom AND align the...

Or ... instead of using "TimeSeries..." classes, use "TimePeriod..." classes. They allow duplicates in the data.

Since someone asked in another thread, I'll copy my response here as well as to a little more detail on determining which data points are within a selecting rectangle.... It is a bit more involved than just a few lines to do this. Essentially, you do the following: - get the chart rendering info fro...

It is a bit more involved than just a few lines.

Thank you for figuring out a fix.

Will this go in the 1.0.10 version, or a later version?
