How to update chart with new data from web service? (already checked other posts)

[Fdde11]

Hi! I have a cartesian-column chart and I need to refresh the chat with new data from a web service, it works fine the first time but after receiving new data the chart "fuses" the old and new data for a second, then flashes back and shows the old data

Here I clean my DataEntry and call my soap, this is done inside a function that is called from a button

dataGraf=new ArrayList<>(); 
new acIndicadores.call_SOAP().execute();

Soap ask for the info and add it to my DataEntry (the only important part here is the last line), I've settled logs so I know my DataEntry is receiving the data that I need.

for(int i = 0; i <=24; i++)
{
                    double vent=0,cob=0;
                    for(int y=0; y<NewDataSet.getPropertyCount(); y++)
                    {
                        gfVentas = (SoapObject) NewDataSet.getProperty(y);
                        if (gfVentas.getPropertyCount()==3)
                        {
                            if(Integer.parseInt(gfVentas.getProperty("hora").toString())==i)
                            {
                                vent=vent+Double.parseDouble(gfVentas.getProperty("Venta").toString());
                            }

                        }
                        else
                        {
                            if(Integer.parseInt(gfVentas.getProperty("hora").toString())==i)
                            {
                                cob=cob+Double.parseDouble(gfVentas.getProperty("Venta").toString());
                            }

 }
dataGraf.add(new CustomDataEntry(Integer.toString(i), vent,cob));

Finally, I call this function from inside an onPostExecute so I know the SOAP-function is over and my data is in the DataEntry

public void setgraph()
    {
        Set set = Set.instantiate();
        set.data(dataGraf);

        Mapping series1Data = set.mapAs("{ x: 'x', value: 'value' }");
        Mapping series2Data = set.mapAs("{ x: 'x', value: 'value2' }");

        cartesian.column(series1Data);
        cartesian.column(series2Data);
        anyChartView.setChart(cartesian);
    }

@Fdde11 There's no need to clean the DataEntry. You can simply override it with new data and apply it to the existing chart. For details, check this comment
