如何在Sencha ExtJS图表中反转轴？ [英] How to reverse an Axis in Sencha ExtJS Charts?

问题描述

我有一个折线图，其中x轴为数字，y轴为数字。我希望将y轴反转，以便较高的值在轴的底部，较低的值在顶部。我看了看API Docu，没有找到使轴反转的配置。有任何线索吗？

I have a line chart with x Axis being numeric and y axis being numeric as well. I want the y axis to be reversed so that higher values are at the bottom of the axis and lower values at the top. I looked at the API Docu and didnt find a config to reverse the axis or so. Any clues?

推荐答案

在ExtJS 3中，有一个反向配置选项可以解决这个问题。使用ExtJS 4，您必须使用变通方法。

In ExtJS 3 there was a reverse config option to get this going. With ExtJS 4 you have to use workarounds.

要还原x轴值，可以使用连接到图表的商店的sorters属性。

For reverting the x axis values you could use the sorters property of the store connected to the chart.

但是要还原y轴，您必须转换值。以下是有关如何实现此目的的示例： http://www.sencha.com/forum/showthread.php?132148-What-has-happen-to-quot-reverse- quot-config-on-chart-axes& p = 949699& viewfull = 1＃post949699

But for reverting the y axis you have to convert your values. Here's a sample on how to achieve this: http://www.sencha.com/forum/showthread.php?132148-What-has-happen-to-quot-reverse-quot-config-on-chart-axes&p=949699&viewfull=1#post949699
