Tooltips for pointlabels

Hello,

I have a bar graph with 2 series, displaying the value at the top of the bar

in a pointlabel.

I would also like to activate the tooltips so that the pointlabel text

displays in the tooltip.

I have set the ShowTips to True and the tipmask to "%v".  The tips are still

not displaying on the chart.  I think I've missed something.

Regards

Russ

This is the code:  I am using ChartFX 6.2

With c

.Gallery = SoftwareFX.ChartFX.Gallery.Bar

.AxisY.LabelsFormat.Format = SoftwareFX.ChartFX.AxisFormat.Number

.AxisY.LabelsFormat.Decimals = 0

.Series(0).Color = Color1

.Series(1).Color = Color.FromArgb(150, Color2)

.PointLabels = True

.PointLabelColor = Color.Black

.PointLabelFont = New Font("Arial", 7, GraphicsUnit.Point)

.ShowTips = True

.TipMask = "%v"

.PointLabelAlign = SoftwareFX.ChartFX.LabelAlign.Center

.Stacked = SoftwareFX.ChartFX.Stacked.No

.SerLegBoxObj.Docked = SoftwareFX.ChartFX.Docked.Top

End With

The Chart is generated from a datatable and I am not generating an image

map.

Let me enable the image map and see what happens.

Thank you for your response.

Hello,

I set the ImgMap to ImgMap.TitleTip and tools tips did display in my charts,

however there is new  issue.

I am using mulitple charts in a sharepoint webpage each in its own webpart.

There are four webparts to the page, think of a square divided into

quadrants.

The top two quads and the lower left quad only have one chart.  The lower

right quad has two charts displayed on top of each other.

Here is the problem.  The tool tip values that are displaying in the top

quads and lower left quads belong to the values of the chart in the lower

left quad.  In the lower right quad the second chart displays the correct

values in the tooltips and the top chart does not display any tooltips.

ImgMap property is set for each chart and as far as I have been able to

determine the chart id's are unique (though I will double check this)

I need each of these charts to display their point values in the tooltips.

Any help will be greatly appreciated.

Regards,

Russ

Hello,

My unique ids were not quite unique enough.  I changed the code slightly and

that problem has been resolved.  I have one more problem.  In one of my

charts the values displayed in the tooltips are incorrect.  The values

displaye are those for the next point to the right on the X axis.  The March

tooltip is displaying April's value and so on, however, the last point

displays the proper value.

What is unusual about this chart is that I had to add 4 new series after

binding so that the first categories display as bar charts and the rest

display as lines and an area.  I think this is what is throwing off the

mapping.

Is there an easy way to resolve this problem or should I just add use the

point's tag property and %L as a code around?

I have attached an excel sheet that contains the chart and the data to help

illustrate my problem.

Thanks for your help.

Regards,

Russ

Thanks for the prompt response.

I tried your suggestion both ways and it did not resolve the issue.

Hello,

Attached is a small project that duplicates the chart in question.  I placed

the txt file that fills the chart in C:\temp.  I have also included the

excel sheet that has points out the problem.   The code the create the

charts is the same code that I am using in my production project.  However I

am having one problem with this demo project  I can duplicate the chart but

I can't get the tooltips displaying so I don't know if this code is

duplicating the original problem.  It is the same code though.

Thanks.

Whoops.  Forgot the id. Sorry about that.

I just added the id and ran the project.  The problem does duplicate.  If

you place the mouse cursor over the blue line (PY in the legend) at March,

the value displayed  is 180,176.  This is April's value.  The PY value for

March should display around 134,000. This continues on until the last point.

August' value is correct.

Thanks.

Another option:

Set:

.MarkerShape = SoftwareFX.ChartFX.MarkerShape.Rect

.ImgMap = ImgMap.TitleTip Or ImgMap.NoConnected

.TipMask = "%v"

This will show tooltips only for the markers not for the segments between 

the markers which elimintes the problem with the segment not belonging to 

any one particular value.

Hello,

I tried the first suggestion with the range, unfortunately the data is still

not correct.

If I move the cursor to the March point of the PY line (blue), it displays

180,175 - 225,043.  This is the range from April to May.

March to April is gone.

Your second suggestion works. Marcy displays 134,139.  Unfortunately the

clients do not want markers on the lines.

I wrote a code around for it.  I set the Tag value with the right value and

use %L. This works.   I was hoping to avoid it.

If you have any other suggestions, I will be happy to try them.

Thank you for your efforts.

Russ

Private Sub SetPointTag(ByVal c As Chart)

Dim i As Integer, iValues As Integer

Dim j As Integer, iSeries As Integer

Dim iPoint As Integer

iValues = c.NValues

iSeries = c.NSeries

For i = 0 To iSeries - 1

For j = 0 To iValues - 1

Select Case j 'Need to do this as a code around. Adding the new series and

setting them to different galleries breaks the image map

Case 0, 1, (iValues - 1)

iPoint = j

Case Else

iPoint = j - 1 'this compensates for the points being shifted by 1 to the

right

End Select

c.Point(i, j).Tag = FormatNumber(c.Value.Item(i, iPoint), 0)

Next

Next

End Sub
