Thank you for your reply but I got to say I missed the point when you say WITHOUT notification do you mean calling the TimeSeries.setNotify(false) or am I missing the plot, please can you clarify for me please. Thanks alot Brian This one's easy to answer... so i will. What I mean is when you add() ...

Ahh crap. Sorry guys, I COMPLETELY forgot that things like TimeTag are intrinsic code for us here. I'm so used to using them, I just assumed EVERYONE had them. Timetags are a way to store time in a specific format used by us. Conversion between Median Julian Time and Milliseconds-since-some-date kin...

Welll, my first thought is that your ChartFactory doesn't create a FastXYPlot, it creates a regular XYPlot. Cant' cast an object to something lower in the hierarchy, and FastXYPlot extends XYPlot. Otherwise, why use TimeSeries? A lot of the efficiency was gained in making a very simple streamlined D...

The zipped file of all the fast classes and the renderes and stuff is something like 80k or so, so I can't IMAGINE that theres so much interest that a limit like that would come into play. If you can provide me with an email address, I'll just send the file off to you and you can then post the url o...

Well if you're truly talking about only 100,000 or so points, 5 minutes seems particularly long. 2 possible solutions. 1) The Element List (may not be QUITE the right name) that is created in teh actual renderer creates a huge array of rectangle2D's that pop up tooltips when your mouse hovers over a...

The number of points you're talking about is no problem. Just don't add them all with notification turned on (a true/false flag in the add method). THAT'S what takes all the time with large series. Add with notification = false, and if a point comes thats out of range, add that point WITH. If you're...

A couple of tricks to reduce memory and such things. 1) Add your points without notification (theres a true/false flag on one of the adds) then add the last one WITH notification. That notification on the last point will go through all the previous points and fix things like range/domain etc. 2) Eli...

This respons is based on my expereince, others can correct me if I'm off. The chartPanel is used to decide the physical size to creat the JFreeChart in. If your chartPanel is 200 pixels by 200 pixels, then the JFreeChart will be created (with axises, legends, titles etc) within that size. If you are...

A question: XYPlot Zoom vs CombinedDomainXYPlot Zoom
Hi, just a question regarding the mouse-zoom abilities. It's not a question of getting it to work, more of a question regarding whether this is the way it was intended to work or not. In the course of our application, both XYPlots and CombinedDomainXYPlots are used (as well as others, of course). Wh...
