Hi,

Can you try this config?

function chart.beforeInit

function chart.beforeInit(sender, config)
{
    config.innerPadding=10;
}

 

[rgreat]

Thank you, it works.

Why not set it by default?

Thank you.

Can you please open a ticket in support portal?

On the other hand this solution is far from perfect.

It adds very large unused borders around diagram.

 

Also seems like amount of text labels is not optimal, and quite low.

Only 2 labels on screenshot above. It could be at least 3:

1.19 not shown unless selected.

It is possible to remove or tune-up text filtering?

One more example:

With tweak:

Both does not look very good.

first: unnecessary clipping.

second:  diagram is too small.

Playing now with insetPadding,

Will update when achieve good results.

These steps improve situation:

1. UniChart.LayoutConfig.BodyPadding := 0; (from 10)

2. For UniPieSeries.SeriesLabel.Display='inside' i recommend using:

config.innerPadding=10;
config.insetPadding=-10;

3. For UniPieSeries.SeriesLabel.Display='outer' and 'rotate' i recommend using:

config.innerPadding=10;
config.insetPadding=30; // or more (depending on labels length)

4. And finally we need a way to reduce calloutLine.length somehow to minimize unused space around diagram.

Dirty source hack:

function TUniCustomSeriesLabel.AsString(AFieldName: string): string;
begin
  if (AFieldName<>'') and (AFieldName[1]<>'[') then
    AFieldName := '"' + AFieldName + '"';

  Result  :=
        '{'+
        'field:'+AFieldName+
          IfThen(FEnabled and (FDisplay<>'none'),
            ',display:"'+ FDisplay +'"'+
            IfThen(FCalloutLine.FVisible, ',calloutLine:true','')+
            ',calloutLine: { length: 25 }'+ //  <----------------------------------------------------------- 20-30.
            IfThen(not FFont.IsDefault, ',font:"'+FFont.ToString(False, False, False, False)+'"','')+
            IfThen(not FFont.Color<>clWindowText, ','+FFont.ToColor(True, False),'')+
            IfThen(FOrientation<>tloHorizontal, ',orientation:"vertical"','')+
            IfThen(FPadding<>20, ',padding:'+IntToStr(FPadding),''),
          '')+
        '}';
end;

Can i set calloutLine at runtime?

5. Missing labels: 

 

6. And finally:

Can i add units in hint?

These are stored in dataset, but seems like not all DS fields are loaded into Chart, so i cant just use them in JS.
