I have attached my chart. How can I change the legend to show the Series Name along with the Total value of the Series?

Hello,
You could use OnGetLegendText event. Ie:
Code: Select all
procedure TForm1.Chart1GetLegendText(Sender: TCustomAxisPanel;
LegendStyle: TLegendStyle; Index: Integer; var LegendText: string);
var i: Integer;
begin
if Index<Chart1.SeriesCount then
LegendText:=LegendText + ' $' + FormatFloat('#,##0.##', Chart1[Index].YValues.Total);
end;

I have another question along this same lines. I have a pie chart of categories (Attached). If transactions don't have any assigned category, the legend just displays the amount. I would like to add the text 'No Categories' in front of the amount but I can't seem to format it the way it is in the legend (Text left justified and amount right justified).
Thanks.

I'm not sure to understand why don't you add the uncategorized value as you do with the others, with the "No Categories" label. Ie:
Code: Select all
Series1.Add(316560, 'No Categories');
In case you are adding the values connecting the series to a dataset, you can loop your values and set the label at those points with empty labels. Ie:
Code: Select all
for i:=0 to Series1.Count-1 do
if Series1.Labels[i] = '' then
Series1.Labels[i]:='No Categories';

Thanks. I ended up using the OnGetLegendText for the Chart and added
Code: Select all
if Series1.Labels[Index] = '' then
Series1.Labels[index]:='No Categories';
Worked perfectly. Thanks.
