hi!I have a problem. There’s the Access database embedded into dbrid using ADO.
In db there is a list of goods,quantity and countries where goods were produced
Now I have to build a diagram for db, for example for countries.
It works quite well but the diagram shows EVERY good, writes a country name and makes a column for each good.
I wonder if there’s a way to make one column for each country.
procedure TForm4.BitBtn1Click(Sender: TObject);
var
m: array of string;
bb: array of integer;
I: integer;
begin
chart1.show;
Chart1.Series[0].Clear;
SetLength(m, Form2.adotable1.RecordCount); // changes mas size
SetLength(bb, Form2.adotable1.RecordCount);
I := 0;
while not Form2.adotable1.Eof do
begin
if Form2.adotable1.FieldByName('country').AsString <> '' then
begin
m* := Form2.adotable1.FieldByName('country').AsString;
bb* := 0;
I := I + 1;
end;
form2.adotable1.Next;
end;
Form2.adotable1.First;
I := 0;
Form2.adotable1.First;
while not Form2.adotable1.Eof do
begin
for I := 0 to length(m)-1 do
if m* = Form2.adotable1.FieldByName
(Form2.DBGrid1.Columns.Items[4].DisplayName).AsString then
bb* := bb* + Form2.adotable1.FieldByName
(Form2.DBGrid1.Columns.Items[6].DisplayName).AsInteger;
Form2.adotable1.Next;
end;
Form2.adotable1.First;
for I := 0 to length(m)-1 do
if m* <> '' then
begin
Chart1.Series[0].Add(bb*, m*, clTeeColor);
end;
end;
Here is the image of my diagram.
Will be grateful for any help!********
