Are these fast classes going to be added to JFreeChart?

Hi


I was wondering if following pseudo 3D-view is possible with JFreeChart (see the middle picture)

Hi I need to use DeviationRenderer with TimeSeries dataset. I looked the DeviationRenderer code and noticed that I have probably two alternatives: either write a new TimeSeries class that has support for deviations or somehow tweak the YIntervalDataset so that it can be plotted to TimeSeries chart. ...

Could you specify what you mean with rendering hints. Should there be some higher level renderer that would use Java2D to do the rendering but also provide support for pluggable optimizers (e.g. pixel optimizer that I described)? Then it would be up to user to choose whether to use optimizers or not...

Sure thing, here it is. /** * Fast XY Plot implementation from * http://www.jfree.org/phpBB2/viewtopic.php?t=18592&postdays=0&postorder=asc&highlight=efficiency&start=15 * * Added some optimization. * * @author WA Technologies Oy (Sami Lakka) * */ public class FastXYPlot extends XYPlot { private sta...

Hi We have to deal with huge datasets in our application (usually over 2 million points). We have developed a custom XYPlot that optimizes the rendering by testing that points that translate to same pixels are drawn only once. I was thinking that could XYPlot be further optimized by first "drawing" ...

I wrote a new version from the FastXYPlot renderFast method. My problem was that I have datasets that have lots of one pixel wide peaks and the previous version seemed to not draw them. This version isn't perfect but it seems to work relatively fast. /** * Performs fast rendering. Skips overlapping ...

Hi, I have created an bar chart and I have an whole bunch of periodic data that I need to display in it. Basically I need to show how the bar lengths vary in time. The problem is that the chart changes the scale of the domain-axis every time I put new measurement in the screen. What I would like to ...
