Formatting pie charts via VBA
Hi,
I'm currently struggling to change the Title and the Legend of pie charts that are generated by passing data from Word to Excel, then copying the chart over to Word. (I'm using Word + Excel 2000). The VBA is use works OK, and generates a reasonable looking chart. However, no matter what I try, I cannot alter the chart title, or the legend. Let me expand on this a little. 1. The Chart Title is always centered. However, the legend (if there a lot of entries in the chart) spills over the title and obscures it. Therefore, I need to position the title on the far left of the chart. 2. If I have more than, say, eight elements in the chart, the legend spills beyond the bottom of the chart, but there seems to be huge spacing gaps between each entry on the legend. However, if I create a chart using an Excel Range and the Chart Wizard, it seems to easily accomodate ten or more entries, and space them nice and evenly. It does not seem to matter whether I set "Legend.AutoScaleFont" to true or false, or whether I try and position the title. It always shows up the exactly the same. I thought I had cracked this, but I obviously need to do some fine tweaking. Any suggestions appreciated. Code below: //// cNumRows and cNumCols are variables used to populate an Excel Range from a Word VBA array of data Set oChart = oSheet.ChartObjects.Add.Chart oChart.SetSourceData Source:=oSheet.Range("A1").Resize(cNumRows, cNumCols), PlotBy:= _ xlColumns oChart.ChartType = xl3DPieExploded oChart.RightAngleAxes = True oChart.PlotArea.Height = 215 oChart.PlotArea.Width = 215 oChart.PlotArea.left = 5 oChart.PlotArea.Fill.Visible = False oChart.PlotArea.Fill.Visible = False oChart.PlotArea.Border.LineStyle = -4142 oChart.Elevation = 30 oChart.Rotation = 80 oChart.Pie3DGroup.VaryByCategories = True oChart.HasTitle = True oChart.ChartTitle.Top = 0 oChart.ChartTitle.left = 0 oChart.ChartTitle.Characters.Text = "Current Asset Allocation" oChart.ApplyDataLabels Type:=xlDataLabelsShowPercent, LegendKey:=False _ , HasLeaderLines:=True oChart.SeriesCollection(1).DataLabels.Font.Size = 8 oChart.HasLegend = True With oChart.Legend .Legend.Shadow = True '.Legend.Position = xlLegendPositionRight .Legend.AutoScaleFont = False .Legend.Font.Size = 3 End With Thanks Neil. |
