Achartengine X labels with uneven interval of time

I am using TimeChartView of AChartEngine 0.7.0 to draw chart.

on x-axis there is dat开发者_开发百科e and for y-axis there is value for specific date. i am parsing these values from xml so someday I get value of complete last 5 day but someday only of 3 days so when i get value of 3 days, chart shows x-values shifted compared to y-values. also sometimes there is repetition of date due to fix number of x-labels which i have solved.

I think i have similar problem to this SO Quest and mostly to this as I want to set X-intervals by using dates.

Here Originally from XML,I am having values of date 28.09,27.09,26.09 but it displays as above.

When the number of (x,y) values are changed suppose from 5 to 3 or vice versa you should first remove the values that repaint the chart

public XYMultipleSeriesDataset dataset = new XYMultipleSeriesDataset();
dataset.getSeriesAt(0).clear(); // use this to clear your data set
dataset.getSeriesAt(0).add(x, y) // use this to add the new x,y values
