achartengine

I am using AchartEngine for my android phone applications. Everything looks fine but the thickness of a line for the rendered graphs does not appeared to be good. I wanted to increase the thickness for these graphs. OK, I got the answer. It should be something like below: int length = renderer.getSeriesRendererCount(); for (int i = 0; i < length; i++) { XYSeriesRenderer seriesRenderer = (XYSeriesRenderer) renderer .getSeriesRendererAt(i); seriesRenderer.setLineWidth(2f); } 来源： https://stackoverflow.com/questions/4678324/setting-line-thickness-for-a-graph-achart-engine

I'm trying to create an achartengine chart within a scrollview but it won't display! It just shows a black screen, but doesn't crash or anything. The thing is if I just change my tag to the chart displays just fine. And in my Java code I do have renderer.setInScroll(true); for the charts renderer. Is this an issue with my xml? Here is my xml: <?xml version="1.0" encoding="utf-8"?> <ScrollView xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="fill_parent" android:orientation="vertical" > <LinearLayout android:layout_height="wrap

(I fixed some issues with saving and loading regarding my previous posts) I am saving some data (mydata) and the date as strings (dates_Strings). In graph activity I load data and dates.And I convert dates_Strings to dates in order to use them in the plot. Now , while entering some data for example "1","2","3" in 10/05/13 I am getting the following image. All good until now. If I try to enter some more data ("3,4,7") in another date (13/05/13) I am getting this image. The dates are superimposed. The MainActivity : The code: //copy the dates_asString to date (Dates) in order to use them in

i have this piece of code. To explain: The user inputs "initcores" data and "ttime" data (the "fcores" is a result). I want to fill the x array with values from 0 to ttime and the y from initcores to fcores and do the scatter plot ,x vs y. I have one problem : If i put " for (double t=0;t<=fcores;t=t+fcores/10.0){ y.add(t); " it gives me a plot but its wrong. if i put " for (double t=initcores ;t<=fcores;..." (which is right because we are starting from initcores) it doesn't appear anything in the plot. Am i not doing sth right here? Thank you! ......... Double initcores= getInitcores();

Is it possible? have anyone been doing this before? I don't know where to start. I mostly need the menu, not the context menu. My "BudgetPieChart" class public class ExpensesByCategoriesPieChart extends AbstractChart{ private DataToArray dta; @Override public String getName() { return MyApplication.getContext().getString(R.string.ExpensesByCategoriesPieChartName); } @Override public String getDesc() { return "The budget per project for this year (pie chart)"; } @Override public Intent execute(Context context) { dta = new DataToArray(); String[] categories = dta.expenseByCategoriesToArray();
