Yahoo! setTickMarkPosition() did the final trick! Thank you! There is still one thing: now the bars widths are too small. I thought, I can change this by setting the XYBarRenderer.setMargin(1.0), but with this value, the bars vanisch! Now, I aks myself why I should have to use TimeSeriesCollection a...

Okay, with the "really big number" for the second argument of XYBarDataset, I get back real bars. So from the data/plot side it looks okay now, but the date axis labels the month ticks at the beginning. Example: the first x value is at 2008-02-29 (end of february) but the axis shows "March 2008" at ...

Okay, I build now a XYSeriesColletion and set the date's milliseconds as the x values and wrap it to a XYBarDataset: result = new XYBarDataset(xysc, 90.0); but it looks weird: the bars all are very thin (no matter if I set "10.0" or "90.0" as the second value of the XYBarDataset constructor. The bar...

I replaced TimeSeriesCollection with getDefaultXYDataset() but get this exception when trying to save the chart: java.lang.ClassCastException: org.jfree.data.xy.DefaultXYDataset cannot be cast to org.jfree.data.xy.IntervalXYDataset at org.jfree.chart.renderer.xy.XYBarRenderer.drawItem(XYBarRenderer....

A TimeSeriesCollection (created via ChartFactory.createTimeSeriesChart(title, xLabel, yLabel, xyd, legend, toolTips, urls)). The bar widths don't have to represent the interval - in fact, it annoyed us and I changed the bar width via setMargin(0.3) to NOT span the whole interval. In the end it is an...

There are ways to work around this, but it depends on the dataset classes you are using. For example, the TimeSeriesCollection class has the setXPosition() method, which you can use to shift the alignment of a times series line chart (it's generally simpler to shift the line than the bars). Tried t...

So, how can I solve this? I just want the line points and bars centers to be the same which I can do via
but this also shows the month ticks and ticklabels at the middle of the month - even though the date values are all "month ends".

When I call setXPosition(), the x locations of the line chart now move rightwards to the center of the bars ... so the line and bars look okay, but are misplaced to the x axis time point. If I leave out the setXPosition() again, the line chart points move backwords to the right position, leaving the...

I have an XY overlay chart with a line chart and a bar chart. The bar chart is using a XYBarRenderer (new StandardXYBarPainter()). The line items are shown correctly an the x locations. The bar items just _start_ at the x locations and end at the subsequent value. How can I shift the bars to the lef...

The 1.0.12 version still says its 1.0.11 ... try { final ResourceBundle rb = ResourceBundle.getBundle("org.jfree.chart.resources.JFreeChartResources"); LOGGER.config("JFreeChart: "+rb.getString("project.name") + " " + rb.getString("project.version")); } catch (final Exception e) { /* ignore */ } Out...

I have an overlayed chart (XYPlot) with a line and a bar (XYBarRenderer) chart. The legend shows a "tall" bar, aligned to the top of the legend border, which looks bad. I thought the default behaviour would at least use some usefull centering, but the items and texts are aligned to the top border. I...

Is it possible to set colors (background colors, frame colors, etc.) to "transparent"?

ARGH!!! I thought I solved this new behaviour by ChartFactory.setChartTheme(StandardChartTheme.createLegacyTheme()); BarRenderer.setDefaultBarPainter(new StandardBarPainter()); and switching of shadows, but now I noticed SOME bar charts that look the old way and some bar charts have the new default ...

The migration section in the JFreeChart Developer Guide explains how to restore the default "look" - essentially you put the following code somewhere near the start of your application (before you create any charts): ChartFactory.setChartTheme(StandardChartTheme.createLegacyTheme()); You'll also ne...

I exchnaged 1.0.10 with 1.0.11 and noticed that all my bar charts now show strange colors in their bars and shadows. Perhaps this should "look like" some shiny, roundness, I don't know. The bad thing is, that the release notes doesn't tell about this change of default behaviour! How can I switch thi...
