java - AndroidPlot: Adding and Removing XYSeries -

i'm having problem implementation:

       if(blueactive) {             blueformat = new lineandpointformatter(color.rgb(0,0,255), null, null);             blue = new simplexyseries(xarray,yarray, selecteddate);             log.e(tag , "blueactive");             cvplot.addseries(blue, blueformat);         }         if(redactive) {             redformat = new lineandpointformatter(color.rgb(255,0,0), null, null);             red = new simplexyseries(xarray,yarray, selecteddate);             log.e(tag , "redactive");             cvplot.addseries(red, redformat);         }         if(greenactive) {             greenformat = new lineandpointformatter(color.rgb(0,255,0), null, null);             green = new simplexyseries(xarray,yarray, selecteddate);             log.e(tag , "greenactive");             cvplot.addseries(green, greenformat);         }          cvplot.redraw(); 

the series plotted correct xarray , yarray, when graph redraws, plots same color. i'm looking code redraw plot 3 different colors. doing logically wrong here?

although question wasn't descriptive other code involved, answer add onclick started process of adding plots:

xarray.clear(); yarray.clear();

the lines overlapping, , when next color added, since red plot selected after blue, 2 arrays grew include points of blue , red, making color wasn't changing. in other words, red array included blue array, , since points identical blue plot, couldn't see blue plot since red plot on top!

i had set log.d long before problem didn't notice array doubling since didn't log count because wanted see x , y values populating.

log array counts , clear arrays rook dawg!!
