问题描述
许志国我在一个柱形图,其中每个酒吧是不同的color.when我显示每个栏重叠other.i想使酒吧我试着用 setBarSpacing之间的空间(图中显示4个值)
通过将不同的价值仍然是其不working.is有任何其他的想法。

我改变了所有的系列 XYSeries
并简单地将它们添加到数据集
,而无需调用额外的方法。
XYSeries系列1 =新XYSeries(A);
dataset.addSeries(系列1);
然后,像在常规XYChart这样添加数据:
series1.add(1值);
series2.add(2值);
Hii i am displaying 4 values in a bargraph where each bar is different color.when i am displaying the graph each bar overlapping each other.i want to make space between the bars i tried with setBarSpacing()
by putting different values still its not working.is there any other idea.

I changed all your series to XYSeries
and add them simply to the dataset
, without calling extra methods.
XYSeries series1 = new XYSeries("A");
dataset.addSeries(series1);
Then, add data like in a regular XYChart like this:
series1.add(1, value);
series2.add(2, value);
这篇关于如何使用Achartengine如果每个酒吧不同的颜色contaning不同的值,以使光柱条之间的空间的文章就介绍到这了,希望我们推荐的答案对大家有所帮助,也希望大家多多支持!
