TBarSeries with "double" values

We are using the TeeChartStandard2014 package.
I have a TBarSeries with some "double" values. I use this sample code:
Code: Select all
var
i, j: Integer;
tmpDates: array of TDateTime;
doADoubleValue: Boolean;
doADoubleValue := False;
setLength(tmpDates, 2);
for i:=0 to High(tmpDates) do
if i mod 2 = 0 then
tmpDates[i]:=IncDay(Today, i*2)
else
tmpDates[i]:=IncDay(Today, (i*2)+1);
for i:=0 to 1 do
with frmChart.ChartAccounting.AddSeries(TBarSeries) as TBarSeries do
begin
//MultiBar:=mbStacked;
MarksOnBar:=False;
MarksLocation:=mlCenter;
CustomBarWidth:=40;
XValues.DateTime:=true;
for j:=0 to High(tmpDates) do
begin
if j mod 2 = 0 then
begin
AddXY(tmpDates[j]+i, 25+random*75, 'S' + inttoStr(i) + ' L' + IntToStr(j));
end
else
begin
AddXY(tmpDates[j], 25+random*75, 'S' + inttoStr(i) + ' L' + IntToStr(j));
if not doADoubleValue then
begin
AddXY(tmpDates[j], 15+random*75, 'test - S' + inttoStr(i) + ' L' + IntToStr(j));
doADoubleValue := True;
end;
end;
end;
end;
I looks like this:
- test.jpg (38.55 KiB) Viewed 5422 times
So the bars with the same values are "overlayed". The same with "mbStacked".
Any idea how to fix this?
Best Regards,
Kai

I solved the problem with this solution:
Code: Select all
var
i, j: Integer;
tmpDates: array of TDateTime;
doADoubleValue: Boolean;
myColor: TColor;
doADoubleValue := False;
setLength(tmpDates, 2);
for i:=0 to High(tmpDates) do
if i mod 2 = 0 then
tmpDates[i]:=IncDay(Today, i*2)
else
tmpDates[i]:=IncDay(Today, (i*2)+1);
for i:=0 to 1 do
with frmChart.ChartAccounting.AddSeries(TBarSeries) as TBarSeries do
begin
//MultiBar:=mbStacked;
MarksOnBar:=False;
MarksLocation:=mlCenter;
CustomBarWidth:=40;
XValues.DateTime:=true;
myColor := Color;
for j:=0 to High(tmpDates) do
begin
if j mod 2 = 0 then
begin
AddXY(tmpDates[j]+i, 25+random*75, 'S' + inttoStr(i) + ' L' + IntToStr(j));
end
else
begin
AddXY(tmpDates[j], 25+random*75, 'S' + inttoStr(i) + ' L' + IntToStr(j));
if not doADoubleValue then
begin
with frmChart.ChartAccounting.AddSeries(TBarSeries) as TBarSeries do
begin
MultiBar:=mbStacked;
MarksOnBar:=False;
MarksLocation:=mlCenter;
CustomBarWidth:=40;
ShowInLegend := False;
Color := myColor;
AddXY(tmpDates[j], 15+random*75, 'test - S' + inttoStr(i) + ' L' + IntToStr(j), myColor);
end;
doADoubleValue := True;
end;
end;
end;
end;
I create a "new" series with the color of the "current" one. Then it works.

Hello Kai,
With your code I get this, that is slightly different to your image:
- 2014-04-14_1547.png (16.51 KiB) Viewed 5368 times
So I guess you are also modifying the bottom axis, setting a bigger range, making the bars to be drawn more close to the other bars.
On the other hand, looking at the data I see you are adding two values at the same XValue in Series1:

Is that what you desired? If so, how would you expect the Bars to be drawn?

Hello Yeray,
we are posting at the same time

Oh sorry ... i post only the code to add the bars.
On the other hand, looking at the data I see you are adding two values at the same XValue in Series1:

Yes i have some values with the same XValue.
so the final looks like this:

So erverthing works fine. Thanx.
