Dynamically adding DataSets and Entries

[PhilJay]

Well, there is no such method like Chart.addDataSet(...) yet. But I will work on that.

In the meantime, you could do a workaround like this:

public void handleNewData(DataSet newData) {

    ChartData cd = mChart.getDataOriginal();
    ArrayList<DataSet> sets = cd.getDataSets();

    // add the new dataset
    sets.add(newData);

    ChartData newCd = new ChartData(sets, cd.getXVals());
    mChart.setData(newCd);
}

I know it's quite ugly, but it should be only a temporary solution. Please let me know if this worked for you.

I'll let you know.

It seems like this technique may end up working after all but what I am doing is bit complicated on my end so it may take awhile. But I also noticed that there might be issue with applying colors. Unless the user decides to apply same array of colors again and again, this would be issue if different color sets are needed.
So keep that in mind to as you develop technique for adding more datasets.

Thanks again for your help. :)

Thank you for your feedback.

I just released the new data model a few hours ago. Colors can now be set directly for each DataSet. The example project already makes use of the new model.

sorry to bother you again..but is there a divider type style for multiple datasets in bar chart? Like a line or space..
Also which specific example are you referring to that implements new data model?

thanx
