如何在条形图中使用Achartengine在不同颜色的条形之间留出空间

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.

Hii在一个条形图中显示4个值，每个条都是不同的颜色。当我显示图形时，每条线互相重叠。我想要在setbarspace()中设置空格，方法是将不同的值仍然设置为无效。还有别的办法吗?

I changed all your series to XYSeries and add them simply to the dataset, without calling extra methods.

我将您的所有系列都更改为XYSeries，并将它们添加到数据集中，而不调用额外的方法。

XYSeries series1 = new XYSeries("A");
dataset.addSeries(series1);

Then, add data like in a regular XYChart like this:

然后，像这样在常规的XYChart中添加数据:

series1.add(1, value);
series2.add(2, value);
