图表上的工具提示未显示 [英] Tooltips on Charts not displaying
问题描述
我无法在我的图表上显示任何工具提示。 以下是我正在尝试添加工具提示的柱形图的代码。 每个系列上的标签显示正确,但工具提示根本不显示。 我需要打开一些其他
属性来显示工具提示吗?
'将标签放在非零数据点上
i = 0
对于
每个 bar
As
仪表板
在 utilizationCollection
myIndex = collMonth.IndexOf(bar.MonthNumber.ToString())
Dim rankLabel
As
String
Dim tooltipLabel
As
String
选择
案例 bar.Rank < span style ="font-size:small">
Case 0
'如果此类型的计数为0,则无标签
Case Else
rankLabel = bar.Rank.ToString()
Chart1.Series(
" Series" & myIndex.ToString).Points( i
Mod 7).Label = rankLabel
Chart1.Series(
" Series" & myIndex .ToString())。Points(i
Mod 7).LabelBackColor =
颜色 。白色
Chart1.Series(
"系列" & myIndex.ToString())。积分(i
Mod 7).LabelForeColor =
颜色 。红色
tooltipLabel =
" herbert" & myIndex .ToString()&
i.ToString()
Chart1.Series(
" Series" & myIndex.ToString())。Points(i
Mod 7).ToolTip = tooltipLabel
结束
选择
i + = 1
下一步 谢谢。
您好,
请在使用数据绑定图表时尝试此操作
Char1.Series(0).ToolTip = Char1.Legends(0).CustomItems(0).Name&":is #VAL"
或
Char1.Series(0).ToolTip =" #VAL"
Hi,
I haven't been able to get any tooltips to display on my charts. Here is the code for a Column chart where I'm trying to add tooltips. The Labels on each Series display correctly, but the Tooltips don't display at all. Is there some other property that I need to turn on to make Tooltips display?
'Put labels on the non-zero datapoints
i = 0
For Each bar As Dashboard In utilizationCollection
myIndex = collMonth.IndexOf(bar.MonthNumber.ToString())
Dim rankLabel As String
Dim tooltipLabel As String
Select Case bar.Rank
Case 0
'No label if the count is 0 for this type
Case Else
rankLabel = bar.Rank.ToString()
Chart1.Series(
"Series" & myIndex.ToString).Points(i Mod 7).Label = rankLabel
Chart1.Series(
"Series" & myIndex.ToString()).Points(i Mod 7).LabelBackColor = Color.White
Chart1.Series(
"Series" & myIndex.ToString()).Points(i Mod 7).LabelForeColor = Color.Red
tooltipLabel =
"herbert" & myIndex.ToString() & i.ToString()
Chart1.Series(
"Series" & myIndex.ToString()).Points(i Mod 7).ToolTip = tooltipLabel
End Select
i += 1
NextThanks.
Hi,
Please try this while you bind the chart with data
Char1.Series(0).ToolTip = Char1.Legends(0).CustomItems(0).Name & " : is #VAL "
OR
Char1.Series(0).ToolTip = "#VAL "
