Jfreechart中条形的宽度 [英] Width of the bar in Jfreechart

问题描述

有没有办法调整条形图中条形的宽度？

Is there a way to adjust the width of the bars in a Barchart?

我使用以下代码创建我的图表。

I create my chart with the following code.

final JFreeChart chart = ChartFactory.createBarChart("Report", // chart title
                "Date", // domain axis label
                "Number", // range axis label
                dataset, // data
                PlotOrientation.VERTICAL, // orientation
                true, // include legend
                true, // tooltips?
                false // URLs?
                );  

推荐答案

您还可以设置条形图的最大宽度。如果你有一个宽图表，但是偶尔只有一个或两个数据点而且你不希望一个大的胖棒占据整个区域，这很有用。

You can also set the maximum width of a bar. This is useful if you have a wide chart but occasionally there are only one or two data points and you don't want a single big fat bar taking up the whole area.

CategoryPlot categoryPlot = chart.getCategoryPlot();
BarRenderer br = (BarRenderer) categoryPlot.getRenderer();
br.setMaximumBarWidth(.35); // set maximum width to 35% of chart
