**Please Note: **
This article is written for users of the following Microsoft Excel versions: 2007 and 2010. If you are using an earlier version (Excel 2003 or earlier), *this tip may not work for you*. For a version of this tip written specifically for earlier versions of Excel, click here: Positive and Negative Colors in a Chart.

Merril asked if there was a way to create a line chart so that when a line represented a negative value, the color of the line would change at the point when it went negative. For instance, in a particular data series, as long as the line represented positive values, it would be blue, but when the line represented negative values, it would change to red.

Unfortunately there is no way to easily do this in Excel. There are, however, a couple of workarounds you can try. The first is to use a macro to change the line colors of chart lines that represent negative values. The following macro is an example of such an approach:

Sub PosNegLine() Dim chtSeries As Series Dim SeriesNum As Integer Dim SeriesColor As Integer Dim MyChart As Chart Dim R As Range Dim i As Integer Dim LineColor As Integer Dim PosColor As Integer Dim NegColor As Integer Dim LastPtColor As Integer Dim CurrPtColor As Integer PosColor = 4 'Green NegColor = 3 'red SeriesNum = 1 Set MyChart = ActiveSheet.ChartObjects(1).Chart Set chtSeries = MyChart.SeriesCollection(SeriesNum) Set R = GetChartRange(MyChart, 1, "Values") For i = 2 To R.Cells.Count LastPtColor = IIf(R.Cells(i - 1).Value < 0, NegColor, PosColor) CurrPtColor = IIf(R.Cells(i).Value < 0, NegColor, PosColor) If LastPtColor = CurrPtColor Then LineColor = LastPtColor Else If Abs(R.Cells(i - 1).Value) > Abs(R.Cells(i).Value) Then LineColor = LastPtColor Else LineColor = CurrPtColor End If End If chtSeries.Points(i).Border.ColorIndex = LineColor Next i End Sub

Function GetChartRange(Ch As Chart, Ser As Integer, _ ValXorY As String) As Range Dim SeriesFormula As String Dim ListSep As String * 1 Dim Pos As Integer Dim LSeps() As Integer Dim Txt As String Dim i As Integer Set GetChartRange = Nothing On Error Resume Next SeriesFormula = Ch.SeriesCollection(Ser).Formula ListSep = "," For i = 1 To Len(SeriesFormula) If Mid$(SeriesFormula, i, 1) = ListSep Then Pos = Pos + 1 ReDim Preserve LSeps(Pos) LSeps(Pos) = i End If Next i If UCase(ValXorY) = "XVALUES" Then Txt = Mid$(SeriesFormula, LSeps(1) + 1, LSeps(2) - LSeps(1) - 1) Set GetChartRange = Range(Txt) End If If UCase(ValXorY) = "VALUES" Then Txt = Mid$(SeriesFormula, LSeps(2) + 1, LSeps(3) - LSeps(2) - 1) Set GetChartRange = Range(Txt) End If End Function

When you select a chart and then run the PosNegLine macro, it looks through the chart and, for line segments between negative data point values, changes the line color to red. For line segments connecting positive data points, the line color is set to green.

The problem with this solution is that it provides only an approximation; it only works with lines connecting two data points, and it can either change the entire line segment or not. If the beginning data point is positive and the ending data point is negative, it cannot change the color of a line right as it passes into negative values.

I'm using Excel 2010 and I've managed to do it using a simple trick: in the Chart tools, go to the Format tab, then Fill, then choose a gradient. Put a color for the position 0%, the same color at 49%, then another color for 51% and this color again for 100%. This way the color changes when the value become positive! :)

This tehcnique with different set of data also works for stacked area charts.

Create from the original data two data series one for the positive values, and the other for the negative values making sure that the negative values in the positive series are blank, and positive values in the negative series are blank. (This is because blanks will not be plotted in a chart). You need to decide how to handle the transition in order to avoid a discontinuity in the a chart.

Then have the chart plot both data series, so the two data series are superimposed
