工具提示图控件 [英] Tooltip Chart Control

问题描述

大家好，

如何使用工具提示在图形中显示点的值(在数据库表中标出的值和对应的值).

到目前为止，我有这个:

Hi All,

How do you display values(plotted and corresponding values in the databasetable) of the point in a graph using Tooltip.

I have this so far:

chart1.DataSource = chartdata;
                      chart1.Series[0].YValueMembers = "LFDepartTemp";
                      chart1.Series[0].ToolTip = "Temp: #VALY{} C" ;

但这只是显示y值.我希望它显示我的数据集中的附加信息.作为示例，请看以下内容:


http://documentation.devexpress.com/#XtraCharts/CustomDocument3440 [

But that just shows the y-value. i want it to show addition information from my dataset. As an example look at this:

but of course without using their product.

Thanks,
Nicole

推荐答案

尝试#VALX获取x值，如果它不起作用，请尝试#AXISLABEL.

Try #VALX for getting x value & if it is not working try for #AXISLABEL.

您好，
试试下面的表达式

Hi,
Try the below expression

报价:

字符串工具提示="title =''{dataSetName}''dvalue =''{value | 0}''";

string toolTip = "title=''{dataSetName}'' dvalue=''{value|0}''";

其中dataSetname表示第三个值，而Value | 0表示y-Value

谢谢

where dataSetname indicates the 3rd value and Value|0 indicated the y-Value
