Re: plot background change 8 to 13

Code: Select all

ChartFactory.setChartTheme(ChartTheme.createLegacyTheme());
should restore the old defaults.
Also search the list. There are a few isolated cases (like shadows on bar charts) that require further code changes.

Re: Text font size resized when the chart panel is reized

This "feature" is affected by these ChartPanel methods

Code: Select all

public void setMaximumDrawHeight(int height)
public void setMinimumDrawHeight(int height)
public void setMaximumDrawWidth(int width)
public void setMinimumDrawWidth(int width)
Adjust accordingly if you want better control over font sizing

Re: Clickable imagemap/tooltip for Axes (or ValueAxis) labels

If you look at the implementation of this method in org.jfree.chart.axis.NumberAxis public AxisState draw(java.awt.Graphics2D g2, double cursor, java.awt.geom.Rectangle2D plotArea, java.awt.geom.Rectangle2D dataArea, org.jfree.ui.RectangleEdge edge, PlotRenderingInfo plotState) You will see that the...

Re: How to change the XYDotRenderer default colors?

Subclass the renderer and override this method

Code: Select all

public java.awt.Paint getItemPaint(int row, int column)
to return whatever value you want. Use the row(=series) and column(=index) arguments to look up the data value being plotted.

Re: Showing Tick for CatagoryAxis

Any time you need to skip category axis labels is a sign that you should be using an XYPlot instead of a CategoryPlot. There are some hackish solutions posted on this list but in my opinion you would be better off using the correct classes instead.

Re: How to set the height of a bar chart to a minimum data value

Assuming I understand your requirements correctly, I don't believe what you are looking for is supported out of the box rangeAxis.setRange(0, 5); will always use 5 as the maximum, even if the maximum is 10. If you wanted to use 5 as the maximum except when the real maximum is > 5, then you would nee...

Re: XYDrawableAnnotation Bug - Set MarkerDemo1 to HorizontalMode

The draw() method of XYDrawableAnnotation looks like it needs to be modified Currently it contains these lines float j2DX = (float) domainAxis.valueToJava2D(this.x, dataArea, domainEdge); float j2DY = (float) rangeAxis.valueToJava2D(this.y, dataArea, rangeEdge); Perhaps this would work better float ...

Re: is it possible to set the zoom possibility on the frame?

Sure. Add the button to the container of the chart. Then call whichever of the many zoom*() methods defined in org.jfree.chart.plot.CategoryPlot and org.jfree.chart.plot.XYPlot is appropriate depending on whether you wish to zoom in/out by a certain fixed amount.

Re: Question on DateAxis set with lowerMargin and upperMargin

setMimumumDate() and setMaximumDate() end up calling ValueAxis::setRange(...), you need to call ValueAxis::setRangeWithMargins(...) instead. I have never tried this and hopefully it will do the right thing with a segmentedTimeLine.
