Hi,

 I've a problem with UserLegendBox in the example in Chart FX ressource Center. (see code below)

When I execute the code, each points in my chart have the same color except if I highlight one of them. Normally i must have directly a different color

I try this in Access 2003 and VB6. I have always the same work.

Sorry for my English :s

 

Could you help me ?

 Thanks

 Chris

 

code :

Chart1.UserLegendBox = True

Dim userLegendBoxItem as Object

Set userLegendBoxItem = Chart1.UserLegendBoxObj.Item(0)

userLegendBoxItem.Label = "Warning"

userLegendBoxItem.Color = RGB(255,0,0)

userLegendBoxItem.MarkerShape = MarkerShape_Rect

userLegendBoxItem.BorderEffect = BorderEffect_None

userLegendBoxItem.BorderColor = RGB(0,0,0)

Set userLegendBoxItem = Chart1.UserLegendBoxObj.Item(1)

userLegendBoxItem.Label = "Caution"

userLegendBoxItem.Color = RGB(255,255,0)

userLegendBoxItem.MarkerShape = MarkerShape_Rect

userLegendBoxItem.BorderEffect = BorderEffect_None

userLegendBoxItem.BorderColor = RGB(0,0,0)

Chart1.OpenData COD_Values, 1, 5

For j = 0 To 4

Chart1.Value(0, j) = (Rnd()) * 100

If ((Chart1.Value(0, j)) > 70) Then

Chart1.Point(0, j) = redPoint

Else

If ((Chart1.Value(0, j)) > 40) And ((Chart1.Value(0, j)) < 70) Then

Chart1.Point(0, j) = yellowPoint

Chart1.Point(0, j) = greenPoint

End If

End If

Next

Chart1.CloseData COD_Values

You should not overwrite actual Point object with your own, rather just change their properties, i.e. try to change this:

redPoint.Color = RGB(255,0,0)...Chart1.Point(0,j) = redPoint

to this:

redColor = RGB(255,0,0)...Chart1.Point(0,j).Color = redColor

(for all lines where you assign colors)
