?? There are some charting requirements in the project, and it's a good idea to start with some open source charting libraries that are powerful and have a wide variety of charts. However, these class libraries often require a lot of setup and do not fit well with the project style. So I try to write a chart library, it is very convenient to use, clear comments, late extensibility.

Class library Access

build.gradleAdd Dependencies in:

     implementation ‘com.openxu.viewlib:OXViewLib:<new version>‘

• 1

Which <new version> is replaced with the latest version, version view Oxchart

Use Example 1, Nightingale Rose figure Nightingalerosechart

??????

<com.openxu.cview.chart.rosechart.NightingaleRoseChart    android:id="@+id/roseChartSmall"    android:layout_width="match_parent" android:layout_height="wrap_content"/>

Nightingalerosechart Rosechartsmall = (nightingalerosechart) Findviewbyid (R.id.rosechartsmall); Rosechartsmall.setshowchartlable (true);Whether the indicator Lablerosechartsmall.setshowchartnum is displayed on the chart (FALSE);Whether the indicator numrosechartsmall.setshownumtouched is displayed on the chart (FALSE);Click Show Quantity Rosechartsmall.setshowrightnum (true);Right Display quantity Roselist.add (New Rosebean (10,new Rosebean (13,  " Data 2 ")), Roselist.add (new Rosebean (31, new Rosebean (8,  "Data 4 "), Roselist.add (new Rosebean (21, //parameter 1: Data object class, Parameter 2: Quantity attribute field name, Parameter 3: Name attribute field name, Parameter 4: Data collection Rosechartsmall.setdata (rosebean.< Span class= "Hljs-keyword" >class,  "Count", false);             

2. Pie-like chart piechartlayout

??????

<Com.openxu.cview.chart.piechart.PieChartLayoutAndroid:id="@+id/piechart1"Android:layout_width="Match_parent"android:layout_height="180DP"Android:layout_centervertical="True"android:paddingright="10DP"Android:background="#ffffff"android:orientation="Horizontal" ><com.openxu.cview.chart.piechart.piechart android:layout_width=" match_parent " Android:layout_height= "match_parent" android:layout_ Weight= "1"/> < Com.openxu.cview.chart.piechart.PieChartLableView android:layout_width= "match_parent" android:layout_height= Match_ Parent "android:layout_weight=" 2 "/> </COM.OPENXU.CVIEW.CHART.PIECHART.PIECHARTLAYOUT>   

Piechartlayout PieChart1 = (piechartlayout) Findviewbyid (R. ID. PieChart1);/* * Ring Width * ringwidth > 0: Hollow Ring, inner ring is white, can be drawn in inner ring * ringwidth <=0: Solid */piechart1. Setringwidth (Densityutil. dip2px (This,15));p IeChart1. Setlinelenth (Densityutil. dip2px (This,8)); Indicator line Length PieChart1. Settagmodul (Piechartlayout. Tag_modul. Modul_chart); Show TagpieChart1 on a fan chart. Setdebug (False);p IeChart1. Setloading (True);//Request data list<piechartbean> DataList = new Arraylist<> ();d atalist. Add (New Piechartbean (20,"Barber Shop"));d atalist. Add (New Piechartbean (20,"KTV"));//displayed in the middle of the lablelist<chartlable> tablelist = new Arraylist<> (); tablelist. Add (New Chartlable ("Architecture", densityutil. sp2px (This,(), Getresources (). GetColor (R. Color. Text_color_light_gray))); tablelist.add (New chartlable (.sp2px (this, 12), Getresources () .color.text_color_light_gray))) ;p iechart1.setloading (false) ;/ /parameter  1: Data type parameter  2: Quantity field Name parameter  3: Name field parameter Span class= "Hljs-number" > 4: Data collection parameters 5:lable collection Piechart1.class,  "Numner",  "Name", DataList, Tablelist)        

3, Progress ring diagram Progresspiechart

??????

<com.openxu.cview.chart.ProgressPieChart    android:id="@+id/chart1"    android:layout_width="120dp" android:layout_height="120dp" android:background="#ffffff"/>

Progresspiechart Chart1 = (progresspiechart) Findviewbyid (R. ID. Chart1); Chart1. Setprosize (Densityutil. dip2px (This,5)); Ring width Chart1. Setdebug (False); Chart1. Setloading (False); Chart1. Setprocolor (Color. Parsecolor ("#ff0000")); Progress color//Ring middle display lablelist<chartlable> lables = new Arraylist<> ();lables.add (New Chartlable (  "60.0%", Densityutil.sp2px (This, 12), Color.parsecolor ( "# ff0000 ")) ;lables.add (New chartlable (" completion rate, Densityutil.sp2px (this, 8), Getresources () .getcolor (R.color.text_color_light_gray)") ;chart1 . SetData (100, 60, lables)    

4, longitudinal column chart Barverticalchart

??????

<com.openxu.cview.chart.barchart.BarVerticalChart    android:id="@+id/chart1"    android:layout_width="match_parent" android:layout_height="250dip" android:background="#ffffff" android:padding="10dp"/>

Barverticalchart Chart1 = (barverticalchart) Findviewbyid (R.ID.CHART1); Chart1.setbarspace (This,1));Double column Spacing Chart1.setbaritemspace (densityutil.dip2px (This,20));Column Spacing Chart1.setdebug (FALSE); Chart1.setbarnum (2);A group of pillars Chart1.setbarcolor (New Int[]{color.parsecolor ("#5F93E7"), Color.parsecolor ("#F28D02")});X-AxisList<string> strxlist =New Arraylist<> ();Column chart datalist<List<barbean>> dataList =New Arraylist<> ();for (int i = 0; I<5; i++) {//this collection is a histogram of data, the collection contains several entities is a few pillars list<barbean> list = new arraylist<> (www.078881.cn  ); list.add (new Barbean (Random.nextint ( 30),  "access System"); list.add (new Barbean (Random.nextint ( 20),  "audit Information"); Datalist.add (list) Strxlist.add ((I+1) + false); Chart1.setdata (DataList, strxlist);     

5, transverse column chart Barhorizontalchart

??????

<com.openxu.cview.chart.barchart.BarHorizontalChart    android:id="@+id/chart1"    android:layout_width="match_parent" android:layout_height="250dp" android:layout_marginTop="20dp" android:background="#ffffff" android:padding="10dip"/>

Barhorizontalchart Chart1 = (barhorizontalchart) Findviewbyid (R.ID.CHART1); Chart1.setbarspace (DensityUtil.dip2px ( This, www.mcyllpt.com/1));Double column Spacing Chart1.setbaritemspace (densityutil.dip2px (This,20));Column Spacing Chart1.setdebug (FALSE); Chart1.setbarnum (3); Chart1.setbarcolor (New Int[]{color.parsecolor ("#5F93E7"), Color.parsecolor ("#F28D02")});X-AxisList<string> strxlist =New Arraylist<> (www.leyou2.net);Column chart datalist<List<barbean>> dataList =New Arraylist<> ();for (int i =0; I<100; i++) {//This collection is a piece of data on a histogram, The collection contains several entities that are several pillars list<barbean> list = new arraylist<> (www.leyouzaixian2.com); list.add (new Barbean (Random.nextint ( 30),  "Lable1"); list.add (new Barbean (Random.nextint ( www.yongshiyule178.com 0),  "Lable2"); Datalist.add (list) Strxlist.add ((I+1) + false); Chart1.setdata (DataList, www.hjha178.com/strXList);
