Help: Need more data in Tooltip.

[Chelsey]

Hello,
  I have a line chart that is working great. I was wondering how I could add extra data to the tooltip? 

Currently I have the yValue contained in it, which is great, I just need a little more. Like a datetime and serial number.

Please help.

Hello Chelsey,

Please check the approach used in our First Look example. You can see how to put more information in your tooltips there.

Hi, great thanks,

No I have a new problem caused by your solution!

The Tooltip is getting populated with bogus data. I'm using the same variable that I used to populate the yValue of the chart.

Every high(er) point has a value of 9102
Every low(er) point has a value of 992
> very strange IMO

Not sure what is causing this, but I did see that in the example there is a #XCAT and #Y{C0} inside the string to populate your tooltip,
 I am really not  sure what this is. I will look into it while I wait for your reply.

/**********UPDATE*********/
OK, I fixed that, but now, yValue is working great in the tool tip, but when I add a string to it, it only shows the last record on ALL of the tooltips.

Here is my code ///

  series_test.Add(New DataPoint(realcount, tempValue))

  series_test.Definition.ItemToolTipFormat = "Gain: #Y" & vbCr & vbLf & "Serial: " & tempSerial

///

What am I doing wrong?

/*****END UPDATE*****/

Thanks,

OK, I figured this one out myself.

I had to create a new DataPoint and add everything in manually -

First I was using ( 
series_test.Add(New DataPoint(realcount, tempValue))
)

to add anything I want into the point label I did this (

     Dim dptest As New DataPoint

                            dptest.YValue = tempValue

                            dptest.XValue = realcount

                            dptest.Tooltip = "Gain: " & tempValue & vbCr & vbLf & vbCr & vbLf & tempResults

                            series_test.Add(dptest)

)
