I'm finding it a bit difficult to figure out how to implement time in the X Axis of a graph in Android?
This is my code:
for (int i = 0; i < listSize; i++)
{
String[] onlyReading = mData.get(i).getReading().split(" ");
readingList[i] = Double.parseDouble(onlyReading[0]);
String date = mData.get(i).getUnFormatedDate();
String[] temp = date.split(" ");
String[] dateTemp = null;
String[] timeTemp = null;
if(temp.length > 0)
{
dateTemp = temp[0].trim().split("-");
timeTemp = temp[1].trim().split(":");
Date dateObj = new Date();
String year = "0";
if(dateTemp != null)
{
dateObj.setDate(Integer.parseInt(dateTemp[0]));
dateObj.setMonth(Integer.parseInt(dateTemp[1]) - 1);
year = dateTemp[2].trim();
if(dateTemp[2].trim().length() == 4)
{
year = dateTemp[2].substring(2, 4);
}
dateObj.setYear(Integer.parseInt(year)+100);
}
if(timeTemp != null)
{
calendar = new GregorianCalendar(Integer.parseInt(year) + 2000, Integer.parseInt(dateTemp[1]) - 1, Integer.parseInt(dateTemp[0]), Integer.parseInt(timeTemp[0]), Integer.parseInt(timeTemp[1]));
}
dateObj = new Date(calendar.getTimeInMillis());
dateList[i] = dateObj;
}
}
if(dateList.length > 0)
{
//dates.clear();
//values.clear();
//readingData.clear();
//readingDate.clear();
GraphViewData[] data = new GraphViewData[dateList.length];
LineGraphView graphView = new LineGraphView(
getActivity() // context
, "" // heading
);
for (int i = 0; i < listSize; i++)
{
data[i] = new GraphViewData(Double.valueOf(i), readingList[i]);
}
GraphViewSeries exampleSeries = new GraphViewSeries(data);
graphView.addSeries(exampleSeries);
graphView.setDrawBackground(false);
((LineGraphView) graphView).setDrawDataPoints(true);
graphView.getGraphViewStyle().setGridColor(0);
graphView.getGraphViewStyle().setHorizontalLabelsColor(Color.WHITE);
graphView.getGraphViewStyle().setVerticalLabelsColor(Color.WHITE);
graphView.getGraphViewStyle().setNumHorizontalLabels(5);
graphView.getGraphViewStyle().setNumVerticalLabels(5);
graphView.setManualYAxisBounds(400, 0);
mGraphParent.addView(graphView);
}
}
Even though I add the Y axis values, I'm not able to figure out how to add time values to the X-axis?
I know it is an old question, but I solved by using DefaultLabelFormatter().
graphView.getGridLabelRenderer().setLabelFormatter(new DefaultLabelFormatter() {
@Override
public String formatLabel(double value, boolean isValueX) {
if (isValueX) {
Format formatter = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
return formatter.format(value);
}
return super.formatLabel(value, isValueX);
}
});
