Re: VectorRenderer - Add Color based upon Dataset
I am having trouble to understand your requirements. Is it something like this: - Intially, you are having multiple datasets (say 3), each with 5 series, and the legend should not reflect the 3*5 series, but only the 3 datasets. - Once the user selects one dataset, the other datasets shall disappear...

Re: Issue with LogAxis and minor grid lines
Looks like a classical bug to me. In the current version of JFreeChart, the LogAxis calculates the minor ticks in a way that seems to be identical to that of a NumberAxis, i.e. with 1, 3, 4, or 9 minor tick lines between major tick lines. In an earlier version, the minor tick count could be explicit...

Re: Bar Chart Negative Values Orientation
If you afe using a CategoryPlot with a BarRenderer, call setBase on the BarRenderer, and use the lowest value in your dataset as parameter.

Re: Suitable chart time for call-stack with duration informa
Hi, I may have misunderstood your problem, but I think that a CategoryPlot might be the wrong plot type, since it gives you little control about the exact positioning of the bars. Try this example, that is using an XYPlot with an XYBarRenderer, and see whether it is what you need: import java.awt.Fo...

Re: Issue in XYSplineRenderer
pls help..how to solve this issue. What issue? The "smoothness" of the curve should be corrected by the precision parametzer as suggested above, and the issue with the curve going above or below the actual data points cant be solved. If you interpolation a spline between data points, and the y valu...

Re: change icons in the MinMaxCategory Renderer?
Looks like you habe now two new renderer classes (the modified MinMax and the one tha derives from the modified MinMax) instead of one.
That really looks like a dirty hack, and not neccessarily less work that the clean approach (which is writing a new renderer).
Anyway, your choice.

Re: change icons in the MinMaxCategory Renderer?
Does anyone have a idea how to work around either the fireChangeEvent() or all the private variables? No, not really. You might be better of by writing your own renderer that extends AbstractCategoryItemRenderer and only implements the features that you need. You could use the BarRenderer class as ...

Re: How To create regression lines (standard deviation chann
1. Group your data into segments, one segment per regression line. We probably won't be able to help on that. 2. Calculate the regression line for the points in each section. 3. Get the first and last x value for each segment, and calculate the corresponding y value with the help of the regression l...

Re: Clicking on Legend
You have mixed some flags (SeriesVisibleInLegend, SeriesVisible, and ItemVisible). Just use the SeriesVisibleInLegend flag, and nothing else.
If a series is not visible, it will not appear in the legend, even it its SeriesVisibleInLegend flag is set to true.

Re: Clicking on Legend
It is doable, but will require some effort. Here is an outline of a possible approach: - Register a ChartMouseListener on the ChartPanel and implement the chartMouseClicked-method. - The ChartMouseEvent parameter gives you a reference to a ChartEntity and a JFreeChart - Check whether the ChartEntity...

Re: Single axis graphs in JFreechart
Use an XYPlot, give the y axis a fixed scale (say, 1), then add your data points where x denotes the time and z has a constant value of 0.5:
