在 Android 中绘制图表
我想在Android中画一个图表,在X轴上我想要像一月,二月,三月,四月,五月,六月,八月,九月,十月,十一月,十二月这样的月份,在Y轴上你花多少钱特定月份。
我有一个在 android 上绘制图表的代码:-
mySimpleXYPlot = (XYPlot) findViewById(R.id.mySimpleXYPlot);
Number[] series1Numbers = { 1, 8, 5, 2, 7, 4 };
Number[] series2Numbers = { 4, 6, 3, 8, 2, 10 };
XYSeries series1 = new SimpleXYSeries(Arrays.asList(series1Numbers),
SimpleXYSeries.ArrayFormat.Y_VALS_ONLY,"Series1");
XYSeries series2 = new SimpleXYSeries(Arrays.asList(series2Numbers),
SimpleXYSeries.ArrayFormat.Y_VALS_ONLY, "Series2");
LineAndPointFormatter series1Format = new LineAndPointFormatter(
Color.rgb(0, 200, 0), // line color
Color.rgb(0, 100, 0), // point color
Color.rgb(150, 190, 150)); // fill color (optional)
mySimpleXYPlot.addSeries(series1, series1Format);
mySimpleXYPlot.addSeries(
series2,
new LineAndPointFormatter(Color.rgb(0, 0, 200),
Color.rgb(0, 0, 100), Color.rgb(150, 150, 190)));
mySimpleXYPlot.setTicksPerRangeLabel(3);
}
但我想在 X 轴上显示月份,在 Y 轴上显示他们在该月花费的具体金额。这些值来自数据库,他们花钱的月份以 mon 他们花费的所需月份的形式出现,名称包含他们在该月花费的值。
try {
myDB = this.openOrCreateDatabase("Expense_db", MODE_PRIVATE, null);
Cursor c = myDB.rawQuery("SELECT project_android.Month AS Month_Real, " +
"SUM(Total) AS OrderTotal FROM project_android " +
"WHERE Year='"+value1+"' " +
"GROUP BY project_android.Month " , null);
int Column1 = c.getColumnIndex("Month_Real");
int Column2 = c.getColumnIndex("OrderTotal");
//int current=0;
// Check if our result was valid.
c.moveToFirst();
if (c != null) {
// Loop through all Results
do {
mon = c.getString(Column1);
Name = c.getDouble(Column2);
Log.i(TAG, "Testing_value_graph_month: " + Name + " | " + mon + " " );
}while(c.moveToNext());
c.close();
}
}
catch(Exception e) {
Log.e("Error", "Error", e);
} finally {
if (myDB != null)
myDB.close();
}

I wanted to draw a graph in Android such that on X axis I want Months like Jan, Feb, March, Apr, May, Jun, Aug, Sep, Oct, Nov, Dec and on Y axis the amount how much you spending in that particular month.
I have a code that draw the graph on an android:-
mySimpleXYPlot = (XYPlot) findViewById(R.id.mySimpleXYPlot);
Number[] series1Numbers = { 1, 8, 5, 2, 7, 4 };
Number[] series2Numbers = { 4, 6, 3, 8, 2, 10 };
XYSeries series1 = new SimpleXYSeries(Arrays.asList(series1Numbers),
SimpleXYSeries.ArrayFormat.Y_VALS_ONLY,"Series1");
XYSeries series2 = new SimpleXYSeries(Arrays.asList(series2Numbers),
SimpleXYSeries.ArrayFormat.Y_VALS_ONLY, "Series2");
LineAndPointFormatter series1Format = new LineAndPointFormatter(
Color.rgb(0, 200, 0), // line color
Color.rgb(0, 100, 0), // point color
Color.rgb(150, 190, 150)); // fill color (optional)
mySimpleXYPlot.addSeries(series1, series1Format);
mySimpleXYPlot.addSeries(
series2,
new LineAndPointFormatter(Color.rgb(0, 0, 200),
Color.rgb(0, 0, 100), Color.rgb(150, 150, 190)));
mySimpleXYPlot.setTicksPerRangeLabel(3);
}
But I want on X Axis the Months and on Y axis particular amount they spend in that month. and these values are coming from database, month in which they are spending money in the form of mon the reuqired month they spend and Name contains the value they spend in that month.
try {
myDB = this.openOrCreateDatabase("Expense_db", MODE_PRIVATE, null);
Cursor c = myDB.rawQuery("SELECT project_android.Month AS Month_Real, " +
"SUM(Total) AS OrderTotal FROM project_android " +
"WHERE Year='"+value1+"' " +
"GROUP BY project_android.Month " , null);
int Column1 = c.getColumnIndex("Month_Real");
int Column2 = c.getColumnIndex("OrderTotal");
//int current=0;
// Check if our result was valid.
c.moveToFirst();
if (c != null) {
// Loop through all Results
do {
mon = c.getString(Column1);
Name = c.getDouble(Column2);
Log.i(TAG, "Testing_value_graph_month: " + Name + " | " + mon + " " );
}while(c.moveToNext());
c.close();
}
}
catch(Exception e) {
Log.e("Error", "Error", e);
} finally {
if (myDB != null)
myDB.close();
}
Any help will be appreciated..!
