Am using androidplot library to display dynamic/static charts & graphs within my Android app. But now I have to export those charts/graphs into excel formats. AndroidPlot library is not providing any API to export the charts/graphs. Is there anyway to do the same?
Can anybody please help me or let me know some workaround to deal with this issue.
That is not a built-in feature of Androidplot however it should be trivial to write a method to suit your needs. All you would need to do is iterate over the XYSeries and write each x/y value to a file separated by a comma. This gives you a generic CSV formatted file that Excel can open. Whether the values or interleaved in or series, how many series are contained in a single file etc, is up to you. To get you started, here's a simple routine that will convert a single XYSeries to an interleaved CSV string. All that's left to do is write the String to file:
/**
* Converts an XYSeries into CSV "x,y,x,y..." format.
* @param series The series to be converted.
* @return CSV formatted version of series.
*/
String toCsv(XYSeries series) {
StringBuffer output = new StringBuffer();
for(int i = 0; i < series.size(); i++) {
output.append(series.getX(i).toString());
output.append(',');
output.append(series.getY(i)).toString();
}
return output.toString();
}
