unichart click

[jahlxx]

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.

Hi Can you info me how to connect chart with database?

[jahlxx]

Hi.

 

I don't know what you mean.

 

Really there is not direct connection between chart and database.

 

I have a dataset, go across the rows of the dataset, adding values to one serie of the chart.

 

that's all.

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.
