我可以将“图表"轴域最大值设置为低于dataMax吗? [英] Can I set the Recharts axis domain max lower than dataMax?

问题描述

我在一种设置中使用图表"，在该设置中，用户将希望看到以不同比例绘制的相同数据.特别是，我需要能够将轴域最大值设置为小于最大数据值(dataMax). 例如，我想在dataMax为20时设置domain={[0,10]}.每当我将域最大值设置为小于dataMax时，都会绘制我的图，以便该域无论如何都升至dataMax.有办法吗?

I'm using Recharts in a setting where users will want to see the same data plotted at different scales. In particular, I need to be able to set the axis domain maximum to be lower than the maximum data value (dataMax); e.g., I want to set domain={[0,10]} when dataMax is 20. I have yet to find a way to do this in Recharts; whenever I set a domain maximum that is lower than dataMax, my plot is drawn so that the domain goes up to dataMax anyway. Is there a way to do this?

推荐答案

我找到了一种方法.您需要使用我已经尝试过的函数语法，但是在函数中没有对dataMax的任何引用.所以这对我有用:

I've found a way to do this. You need to use the functional syntax, which I had already tried, but without any reference to dataMax in the function. So this is what worked for me:

domain={[ 0, dataMax => (10) ]}    

您当然可以在括号内使用更详细的代码；诀窍是您不能以任何降低其值的方式使用dataMax变量.也就是说，您不能使用dataMax => (dataMax/2)或dataMax => (dataMax - 10).

You can of course use more elaborate code inside the parentheses; the trick is that you cannot use the dataMax variable in any way that reduces its value. That is, you can't use, say dataMax => (dataMax/2) or dataMax => (dataMax - 10).
