In my android program I am using achartengine library for showing a pie chart.
The basic of the program is I have an activity,where I have 2 edit text fields and a button.after fill up the edit text field ,when click the button it will show a popup window with piechart..
here,I am using NAME_LIST as a string type array. where value of edit text will store and after we can fetch..
the code is given below:---
public class AndroidPopupWindowActivity111_new extends Activity {
private static int[] COLORS = new int[] { Color.MAGENTA, Color.CYAN };
LinearLayout layout;
private CategorySeries mSeries = new CategorySeries("");
private DefaultRenderer mRenderer = new DefaultRenderer();
private GraphicalView mChartView;
EditText name1,name2;
private int[] VALUES = { 40,60 };
String x1,y1;
String[] NAME_LIST ;
/** Called when the activity is first created. */
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.popup_main);
name1=(EditText) findViewById(R.id.ext1);
name2=(EditText) findViewById(R.id.ext2);
x1=name1.getText().toString();
y1=name2.getText().toString();
NAME_LIST = new String[] { x1 , y1 };
mRenderer.setApplyBackgroundColor(true);
mRenderer.setBackgroundColor(Color.argb(100, 50, 50, 50));
mRenderer.setChartTitleTextSize(20);
mRenderer.setLabelsTextSize(15);
mRenderer.setLegendTextSize(15);
mRenderer.setMargins(new int[] { 20, 30, 15, 0 });
mRenderer.setZoomButtonsVisible(true);
mRenderer.setStartAngle(90);
final Button btnOpenPopup = (Button)findViewById(R.id.openpopup);
mChartView = ChartFactory.getPieChartView(this, mSeries, mRenderer);
btnOpenPopup.setOnClickListener(new Button.OnClickListener(){
#Override
public void onClick(View arg0) {
LayoutInflater layoutInflater = (LayoutInflater)getBaseContext() .getSystemService(LAYOUT_INFLATER_SERVICE);
View popupView = layoutInflater.inflate(R.layout.main_piechart, null);
final PopupWindow popupWindow = new PopupWindow( popupView, LayoutParams.WRAP_CONTENT,LayoutParams.WRAP_CONTENT);
layout = (LinearLayout)popupView.findViewById(R.id.chart);
layout.addView(mChartView);
for (int i = 0; i < VALUES.length; i++) {
mSeries.add(NAME_LIST[i] + "(" + VALUES[i]+"%)", VALUES[i]);
SimpleSeriesRenderer renderer = new SimpleSeriesRenderer();
renderer.setColor(COLORS[(mSeries.getItemCount() - 1) % COLORS.length]);
mRenderer.addSeriesRenderer(renderer);
}
if (mChartView != null) {
mChartView.repaint();
}
Button btnDismiss = (Button)popupView.findViewById(R.id.dismiss);
btnDismiss.setOnClickListener(new Button.OnClickListener(){
#Override
public void onClick(View v) {
popupWindow.dismiss();
}});
popupWindow.showAsDropDown(btnOpenPopup, 50, -30);
}});
}
}
But the problem is the name is not fetching from edittext..I am giving an example what error is occuring.:--
Click the picture to know the problem...in this picture A,B,C,D is the edit text values..in my output A,B,C,D is showing as "null"
where is the problem??????????thanks in advance
When you're initializing
String[] NAME_LIST = new String[] { x1,y1 };
x1 and y1 are null. Changing the values of x1 and y1 later will not change the values in NAME_LIST.
Add the line
NAME_LIST = new String[] { x1,y1 };
just before the for loop in OnCreate(). It will work.
EDIT:
Move these five lines
name1=(EditText) findViewById(R.id.ext1);
name2=(EditText) findViewById(R.id.ext2);
x1=name1.getText().toString();
y1=name2.getText().toString();
NAME_LIST = new String[] { x1 , y1 };
into the onClick() method, just before the for loop begins.

In my program, the basic is:-
When the program open it will show an animation then it will show pie chart result.

But the problem is when I open the program, animation is running and running.the result is not coming.
I requirement was first animation then the result..But only animation is running.. Where is the problem in my code? thanks in advance

Try call anim.setAnimationListener() before call iv.startAnimation(anim);
Am using AChartEngine library to displaying data's in PieChart view in my project. Initially I created Dataset, Render, View and Chart Factory to create PieChart and its working fine. For eg PieChart for Gender
OnCreate(){
malecount = 3;
femalecount = 1;
createpiechart(); // Creating PieChart initially
}
This code is working fine. PieChart with male & Female with 2 different colors that mentioned as static.
Now I add Spinner for filters, add event for that Spinner OnItemSelectedListener.
String selectedItem = parent.getItemAtPosition(position).toString();
if(selectedItem.equals("Last Week"))
{
malecount = 2; femalecount = 1; // clear existing values from temp memory and add new values
mSeries.clear(); // clear the dataset
createpiechart(); // recreate piechart
}
in that create piechart method again execute the same code as before.
private void createpiechart() {
VALUES = new int[] { malecount, femalecount };
mRenderer.setChartTitle("Gender");
mRenderer.setChartTitleTextSize(20);
mRenderer.setLabelsColor(0xff000000); // Black color
mRenderer.setLabelsTextSize(15);
mRenderer.setLegendTextSize(15);
mRenderer.setMargins(new int[] { 20, 30, 15, 0 });
mRenderer.setZoomButtonsVisible(true);
mRenderer.setStartAngle(90);
for (int i = 0; i < VALUES.length; i++) {
mSeries.add(NAME_LIST[i] + " " + VALUES[i], VALUES[i]);
SimpleSeriesRenderer renderer = new SimpleSeriesRenderer();
renderer.setColor(COLORS[(mSeries.getItemCount() - 1)
% COLORS.length]);
mRenderer.addSeriesRenderer(renderer);
}
if (mChartView != null) {
mChartView.repaint();
}
if (mChartView == null) {
LinearLayout layout = (LinearLayout) findViewById(R.id.chart);
mChartView = ChartFactory.getPieChartView(this, mSeries, mRenderer);
mRenderer.setClickEnabled(true);
mRenderer.setSelectableBuffer(10);
mChartView.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View arg0) {
// nothing
}
});
layout.addView(mChartView, new LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.FILL_PARENT));
}
else {
mChartView.repaint();
}
}
After executing the same code Green and Blue color of Male & Female in Bottom changes to white color, I need same color before it shown. Check this image below and help me how to change that color back or whats wrong with this code ?
Just clear Dataset and Renderer and then pass new values.
To clear dataset
int size = dataset.getSeriesCount();
for (int i = 0; i < size; i++) {
dataset.removeSeries(0);
}
To clear Renderer renderer.removeAllRenderers();
I m trying to set doughnut chart inner circle radius and outter circle radius in aChartengine, below is my code :
public class MainActivity extends Activity {
GraphicalView gv;

setContentView(R.layout.activity_main);
List<double[]> values1 = new ArrayList<double[]>();
values1.add(new double[] { 15, 5 });
gv = createIntent(values1);
rl = (RelativeLayout) findViewById(R.id.rel);
rl.addView(gv);
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
public GraphicalView createIntent(List<double[]> values1) {
List<String[]> titles = new ArrayList<String[]>();
titles.add(new String[] { " ", " " });
int[] colors = new int[] { Color.BLUE, Color.GREEN };
DefaultRenderer renderer = buildCategoryRenderer(colors);
renderer.setApplyBackgroundColor(true);
renderer.setShowLegend(false);
renderer.setShowLabels(false);
renderer.setStartAngle(270);
renderer.setBackgroundColor(Color.rgb(222, 222, 200));
renderer.setLabelsColor(Color.GRAY);
return ChartFactory.getDoughnutChartView(MainActivity.this,

renderer);
}

List<String[]> titles, List<double[]> values) {
MultipleCategorySeries series = new MultipleCategorySeries(title);
int k = 0;
for (double[] value : values) {
series.add(2007 + k + "", titles.get(k), value);
k++;
}
return series;
}
protected DefaultRenderer buildCategoryRenderer(int[] colors) {
DefaultRenderer renderer = new DefaultRenderer();
renderer.setLabelsTextSize(15);
renderer.setLegendTextSize(15);
renderer.setMargins(new int[] { 20, 30, 15, 0 });
for (int color : colors) {
SimpleSeriesRenderer r = new SimpleSeriesRenderer();
r.setColor(color);
renderer.addSeriesRenderer(r);
}
return renderer;
}
But I have browser this query of setting radius , in many search I have found radius on canvas but in my case I don't have canvas.
Can anyone tell me how to set radius here in my code ?
renderer.setScale((flaot)1.3) solved my problem but the inner and outer radius is approx not prefect.
You have to just chage value of decCoef (variable in DoughnutChart class).
In DefaultRenderer add your own radius variable and create getter and setter.
now, use this variable in DoughnutChart.
for example ,
DefaultRenderer defaultRenderer = new DefaultRenderer();
defaultRenderer.setmWidth(0.1f);
In DoughnutChart class :
public class DoughnutChart extends RoundChart {
private float mWidth; // make your own variable and initialize in constructor
public DoughnutChart(MultipleCategorySeries dataset, DefaultRenderer renderer) {
super(null, renderer);
mDataset = dataset;
mWidth = renderer.getmWidth();
}
double decCoef = mWidth / cLength; // change value of decCoef by using our variable.
I am using aChartEngine Library to draw donut in my android application.I want to make two donut - one inside another with two different color. But I am unable to make them with two different color.This is my donut class which draw donut in LinearLayout.
public class PunchStatGraph {
private GraphicalView mChartView2;
static int count = 2;
int[] Mycolors = new int[] { Color.parseColor("#D4272D"),
Color.parseColor("#6F1717") };
String[] average = { "SPEED", "FORCE"};
String[] max = { "SPEED", "FORCE"};
public Intent execute(Context context, LinearLayout parent, double avg_values[],double max_values[]) {
parent.removeAllViews();
int[] colors = new int[count];
for (int i = 0; i < count; i++) {
colors[i] = Mycolors[i];
}
DefaultRenderer renderer = buildCategoryRenderer(colors);
renderer.setShowLabels(false);
renderer.setBackgroundColor(Color.BLACK);
renderer.setPanEnabled(false);// Disable User Interaction
renderer.setScale((float) 1.4);
renderer.setInScroll(true); //To avoid scroll Shrink
renderer.setStartAngle(90);
renderer.setShowLegend(false);
MultipleCategorySeries categorySeries = new MultipleCategorySeries(
"Punch Graph");
categorySeries.add(average, avg_values);
categorySeries.add(max, max_values);
mChartView2 = ChartFactory.getDoughnutChartView(context,
categorySeries, renderer);
parent.addView(mChartView2);
return ChartFactory.getDoughnutChartIntent(context, categorySeries,
renderer, null);
}
protected DefaultRenderer buildCategoryRenderer(int[] colors) {
DefaultRenderer renderer = new DefaultRenderer();
for (int color : colors) {
SimpleSeriesRenderer r = new SimpleSeriesRenderer();
r.setColor(color);
renderer.addSeriesRenderer(r);
}
return renderer;
}
}
Check Image also.Thanks in advance.
I am new to AchartEngine. I am using AchartEngine with android to create a Barchart. I have looked at the aChartEngine API and have created a Barchart, its working fine.
When I want to see my actual view I have to decrease the zoom rate by clicking zoom button which is in right bottom. I need to show a compleate Barchart what I exactly declared in my program with out using zoom button.
I need to navigate from one view to another. So, I created one graphical view with ontouchlistner, but it shows error.
Any ideas would be greatly appreciated. Am I missing something here?
