Hi.

 

I'm starting with unichart. I've 2 questions:

 

 

- When I click in one leyend, the pie corresponding to that leyeng disapears fom the pie chart. why?

 

- I'd like to put the legend in the "legend zone", and put the values in the pie's of the pie chart, not the same legend.

 

Some help whith this, please.

 

Thanks.

Hi,

Yes, this is the default behavior in ExtJS

 

For disable this behavior, for now can you try this?!:

 

1. In MainForm.Script add this:

Ext.onReady(function() {
    Ext.chart.LegendItem.override({
        onMouseDown: function() {
            var me = this;
            if (me.legend.enableItemEvents !== false) {
                me.callParent(arguments);
            }

        }
    })
})

2. UniChart -> ClientEvents -> UniEvents -> Ext.chart.Chart [chart] add chart.beforeInit fn:

function chart.beforeInit(sender, config)
{
    config.legend.enableItemEvents = false
}

Best regards.

Hello irpans,

 

Yes you can   :)

 

Unigui actually implemented  DataSource only  in  UniBarSerie

if you want it for PieSeries, or else  you have to add . DataSource  manually :

 
begin
  UniPieSeries1.DataSource:=DataSource1;
  UniPieSeries1.XLabelsSource:= YourField_NameX;              // a String
  UniPieSeries1.YValues.ValueSource:=  YourField_NameY;   // a String
 
 
  UniChart1.BeginUpdate;
  UniChart1.RefreshData;
  UniChart1.EndUpdate;
 
end;
 
Regards.
