问题描述
由于某些原因，轴和网格未显示在c＃图表上。从两张图片中可以看到，图表的背景正在显示，但没有其他内容。谁能帮我弄清楚为什么未显示图表中的网格和信息？
For some reason the axis and grid is not being displayed on the c# chart. as you can see from the two pictures, the background of the chart is being displayed, but nothing else is. Can anyone help me figure out why the grid and information from the chart is not being displayed?

推荐答案
您的代码可以正常工作，但是您需要添加 DataPoint 来触发图表
Your code works fine but you need to add a DataPoint to trigger the Chart's display.
这很可能是因为自动设置没有任何数据，这是大多数元素（包括 ChartArea）默认的设置的 Size ，没有任何用处。我尝试了一下，甚至在添加了虚拟点之后，网格和所有其他不错的细节也都很好显示..：
This is most likely because without any data the automatic settings, which are default for most elements, including ChartArea's Size, have nothing to work from. I tried it and after adding even a dummy point the grid and all other nice details will show just fine..:
如您所见，清除 DataPoints 将再次清除图表。
As you can see clearing the DataPoints will wipe out the chart again..
如果您想清除系列的虚拟数据，则可以在添加第一个数据后删除该虚拟数据，也可以添加一个虚拟数据系列。
If you want your Series clean of dummy data you can either delete the dummy after adding the first data or add a dummy series..
