JFree folks,

Is there a simple way to change the default behavior for all charts, w/o doing a lot of setFont's within the code?

It seems to rely on JFreeChart.DEFAULT_FONT, but I'm not sure how I can change those values at runtime?

thanks,
andrew

maybe answered my own question here, looks like in the newer releases there's an XY3DLineRenderer, so maybe good to go, if I can figure out the right 3DPlot to go with it.

Has anyone done anything with making the line charts 3D?

I'd like to do it and make the line chart w/ a dropshadow, but wanted to be sure I wasn't recreating the wheel here.

thanks,
andrew

Ralph, sorry about that, I neglected to include it. The gradientpainttransformer should be able to be added to most of the renderers that actually fill in an area, it's in BarRender already. Here's my XYDifferenceRendererFill, it makes sort of a hybrid between a difference chart and an area chart. I...

JFree folks, the topic of animating charts has come up on the list a few times in the past and I've tried a few approaches, but so far the best is to change the gradient paint, since the gradient helps smooth things regardless of how fast or consistently the repaints are happening. Following is Vari...

Has anyone any experience w/ or suggestions for ways of making the initial painting of the chart be animated? Everyone seems to like the flashy dynamic animation of charts as they first appear, such that the lines or bars seem to grow into their values, but my attempts to emulate this have come up f...

Has anyone created any custom, annotated or color coded axes? I'm contemplating a ValueAxis, that highlights red/yellow/green values, maybe by drawing sections of the axis line in different colors, as an alternative to putting markers on the plot, which can be just a little too prominent. thanks, an...

Dave,

that did it, thank you very much!

I built a test chart to show it, but can't figure out how to attach, just as well, I think this is the right track, I poured over this area trying to understand, but it escaped me.

Definitely confirmed that iterative fireDatasetChanged is only resulting in one draw of the chart when the chartpanel is useBuffer true

if useBuffer false, fireDatasetChanged triggers all 10 iterative redraws just fine.

I'm stumped.

I'm doing a progressive draw of the chart and it's a pretty complex chart, it's slow but it works. The dataset has a scaler factor which scales the getY result and does a firedatasetchanged(). I set a chartprogresslistener for the DRAWING_FINISHED event and set the next scaler, until the dataset is ...

Martin, have you continued progress on this? I started a simliar tack, extending an XYDataset, I really only need 2D for starters to do lat/longs, as either decimal or minutes/seconds and draw a simple XYPlot over a chart image background w/ an anchor value lat/long. The plot has no axes and I was u...

I'm using a combinedRangeXYPlot, using XYDifference render, which does 2 drawing passes and a bunch of datasets, so a redraw is not a minor event:-) Can I separate out the plots make them transparent and layer them on top of one another, the redraw the layers? Except making transparent, may cause th...

Is it possible to control the drawing, such that only portions of the chart are redrawn?

That's much better thankyou, not as smooth as I'd like but this is a much better way to do it...

Has anyone come up w/ a good strategy for animating the charts? Seems like the in thing in the flash charts is the animated growing of the bars when they plot. I prototyped extending my dataset, adding a scaler setting and the getYValue returns a scaled value. dataset.setScaler, calls fireDatasetCha...
