DefaultXYDataset.renameSeries
Hi, I am currently working on a graphical JFreeChart frontend to generate scatter plots. I am using the DefaultXYDataset to store the data. However, one requirement is that the user is able to change the names of the series after the chart has been created. Using the DefaultXYDataset as it is, I can...

Hi MH23, somebody correct me whem I am mistaken: XYBlockRenderer.drawItem is NOT responsible for drawing the Plot but for drawing individual items. XYBlockRenderer.drawItem is called repetetively from one of the XYPlot functions that is responsible for drawing the plot. The chart size is not determi...

Who on earth is going to be able to distinguish between more than 500 tick labels? Assuming a plot width on screen of 1000 pixel, even 500 ticks would result in a new tick every 2 pixels. In printed form, the situation is similar: assuming a width of 8in and a resolution of 72 dpi (IIRC thats the de...

First find the axis with the larger value range and then use the larger value as new upper bound for both axes. I assume that the methods double getUpperBound() and void setUpperBound(double max) in class org.jfree.chart.axis.ValueAxis can do that. //untested code fragment double max1 = valueAxis1.g...

Sounds strange. At first, I had assumed that for some reason the renderer was not assigned properly to the plot (maybe missing some dataset), but in that case not only the legend but also data points in the graph should be wrong. Can you post some code? If possible, a compilable example. Regards, pa...

Hi, I have started to develop one to generate XY scatter charts from informations read from csv files. You can assign one column in the data source file to the x-axis or "domain axis" and as many columns as you wish to different y axes or "range axes". For each data series, you can define the stroke...

You seem to generate a graph in your DrawGraph() method based on a TimeSeriesCollection with a single, empty TimeSeries, put that f graph in a frame, and then start to modify the data. I conclude that from variable name "tseries" that is used twice. What about first generating the TimeSeriesCollecti...

Another EPS generator in Java that seems to generate EPS through Java2D calls is included in the Apache XML Graphics Commons package.
http://xmlgraphics.apache.org/commons/
I haven´t tried it myself but will probably do that in some time.

Hi Matthew, LookupPaintScale works for me as expected. Here is a demo: a small 9x9 matrix where the z coordinate is the product of the x and y coords. The "heat gradient" used for visualization is a bit coarse (is that the right word?) but sufficient as a proof-of-concept. No idea about getting the ...

setSeriesShape() of cloned XYRenderer for 2nd dataset
Hi there, First of all, I would like to say "thank you" for making such a great thing like JFreeChart available. I have spent some time to look for a charting program that would allow the creation of nice looking, feature-rich charts w/o learning a new programming language or fooling around with a c...
