[英]Formatting Y-axis on JFreeChart
I have a StackedXYAreaChart similar to the one below: 我有一个StackedXYAreaChart类似于以下内容:
On the Y-axis, instead of the tick units shown ( 2.5
, 5.0
, 7.5
, 10.0
, etc.), I have the following: 100,000
, 200,000
, 300,000
, 400,000
, etc. These represent Bytes, just like the one above. 在Y轴,而不是蜱单位表示(
2.5
, 5.0
, 7.5
, 10.0
等),我有以下: 100,000
, 200,000
, 300,000
, 400,000
等。这些代表字节,就像上面的一个。 My question is: is there a way I could format these tick units such that they represent Kilobytes, ie 100
, 200
, 300
, 400
, etc. or even Megabytes, ie 0.1
, 0.2
, 0.3
, 0.4
, etc.? 我的问题是:有一个方法,我可以格式化这些蜱单元,使得它们代表千字节,即
100
, 200
, 300
, 400
等,或甚至兆字节,即0.1
, 0.2
, 0.3
, 0.4
,等? I don't want to display 10 MB as 10,000,000
on the Y-axis. 我不想在Y轴上将10 MB显示为
10,000,000
。
Thanks! 谢谢!
The static factory createStackedAreaChart()
instatiates a NumberAxis
for the range. 静态工厂
createStackedAreaChart()
将范围的NumberAxis
实例化。 The NumberAxis
method createStandardTickUnits()
creates the standard tick units, which may serve as an example for creating your own units. NumberAxis
方法createStandardTickUnits()
创建标准的刻度单位,可以用作创建自己的单位的示例。 In particular, "If you don't like these defaults, create your own instance of TickUnits
and then pass it to the setStandardTickUnits()
method." 特别是,“如果您不喜欢这些默认值,请创建自己的
TickUnits
实例,然后将其传递给setStandardTickUnits()
方法。” There's more details here . 还有更多的细节在这里 。
I would of done a byte conversion, converting from 我会做一个字节转换,从
KB to MB=(KB/1024)
KB to TB=(KB/(1024*2))
KB to GB=(KB/(1024*3))
KB to PB=(KB/(1024*4))
Where the the NumberAxis should auto range depending on the value passed. NumberAxis应根据传递的值自动调整范围。
