android - Achartengine XYMultipleSeriesRenderer renderes chart for null values and shows undesired spacing b/.w bars -


image screen shot belowi have developed bar chart using chart engine, , have used multiple series showing different colored bars on basis of customisation done on data.

but when there null value 1 bar , xymultiseriesrenderer still renders chart , creates undesired spaces between bars.

private void openchart(){             //int[] x = { 0,1,2,3,4,5,6,7,8,9};             int[] income = { 230,220,230,250,270,300,280,350,370,400};             int[] expense = {220, 270, 290, 280, 260, 300, 330, 340};              int[] colors = {color.green,color.yellow , color.red , color.blue};              xyseries[] incomeseries = addincomeseriestodataset(income);             xyseries expenseseries = constructexpenseseries(expense);             // creating dataset hold each series             xymultipleseriesdataset dataset = new xymultipleseriesdataset();             // adding income series dataset             for(int i= 0 ; i< incomeseries.length ; i++) {                 dataset.addseries(incomeseries[i]);             }             //adding expense series dataset             dataset.addseries(expenseseries);              // creating xymultipleseriesrenderer customize whole chart             xymultipleseriesrenderer multirenderer = buildrenderer(colors);               // creating intent plot bar chart using dataset , multiplerenderer             intent intent = chartfactory.getbarchartintent(getbasecontext(), dataset, multirenderer,       type.default);       // start activity             startactivity(intent);          }private xyseries[] addincomeseriestodataset(int[] income){             xyseries[] incomeseries = {new xyseries("income<=250") , new xyseries("income<320") , new       xyseries("income>320")};             // adding data income series             int = 0;             int sizex = mmonth.length;             int incomeitemscount = income.length;              while(i<sizex && i<incomeitemscount){                 if(income[i] <= 250) {                     incomeseries[0].add(i, income[i]);                                 } else if(income[i] <= 320) {                      incomeseries[1].add(i, income[i]);                  } else {                  incomeseries[2].add(i, income[i]);                 }                i++;             }             return incomeseries;         }          private xyseries constructexpenseseries(int[] expense) {             xyseries expenseseries = new xyseries("expense");                int i=0;                int sizex = mmonth.length;                int expenseitemscount = expense.length;                while(i<sizex && i< expenseitemscount) {                     expenseseries.add(i,expense[i]);                     i++;                 }               return expenseseries;          }         private xymultipleseriesrenderer buildrenderer(int[] colors) {             xymultipleseriesrenderer renderer = new xymultipleseriesrenderer();             renderer.setaxistitletextsize(16);             renderer.setcharttitletextsize(20);             renderer.setlabelstextsize(15);             renderer.setlegendtextsize(15);             renderer.setxlabels(0);             renderer.setaxescolor(color.blue);              renderer.setxlabelscolor(color.blue);             renderer.setylabelscolor(0,color.blue);              renderer.setxlabelsalign(align.center);             renderer.setcharttitle("income vs expense chart");             renderer.setxtitle("year 2012");             renderer.setylabelsalign(align.right);             renderer.setlabelscolor(color.blue);             renderer.setytitle("amount in dollars");             renderer.setbarspacing(1.0);             renderer.setmarginscolor(color.white);             renderer.setapplybackgroundcolor(true);             renderer.setbackgroundcolor(color.white);             renderer.setmargins(new int[] { 20, 30, 15, 0 });             renderer.setzoombuttonsvisible(true);             for(int i=0; i< mmonth.length ;i++){                 renderer.addxtextlabel(i, mmonth[i]);             }             int length = colors.length;             (int = 0; < length; i++) {                 xyseriesrenderer r = new xyseriesrenderer();                 r.setcolor(colors[i]);                 r.setlinewidth(4);                 r.setfillpoints(true);                 r.setdisplaychartvalues(true);                 renderer.addseriesrenderer(r);             }             return renderer;

you have setbarspacing(1.0) call in code. remove that.

php - Why I am getting the Error "Commands out of sync; you can't run this command now" -

the documentation of error mentioned in title says if commands out of sync; can't run command now in client code, calling client functions in wrong order. this can happen, example, if using mysql_use_result() , try execute new query before have called mysql_free_result(). can happen if try execute 2 queries return data without calling mysql_use_result() or mysql_store_result() in between. from here: http://dev.mysql.com/doc/refman/5.0/en/commands-out-of-sync.html but in first query not fetching data mysql database, inserting. , in second query getting data database. here code $connection = mysqli_connect("localhost","username","password","tbl_msgs"); if(mysqli_connect_errno($connection)) { die("failed connect mysql: " . mysqli_connect_error()); } $query = "insert users (total_comments, total_views) values ({$total_comments}, {$total_views});"; $query .= "insert msgs (no...

linux - Does gcc have any options to add version info in ELF binary file? -

i mean whether gcc can insert source code version infor elf binary section or similar. not want change source file, add info gcc option in makefile. you can emit version info text file, turn text file object file statically link executable. the first step simple have write code: script or write version info in format plain text file. write makefile rule produce version.o version.txt, using objcopy . you'll have object file 2 useful symbols defined in it: beginning , end of textual version info. add generated object executable, , you'll able access version 2 ways: running strings on binary, or writing code in application print version string (you'll need declare start , end symbols variables in header file).

java - Are there any classes that implement javax.persistence.Parameter<T>? -

i'm using named queries fetch entities database using jpa , hibernate , came across puzzling me: how come there no default implementations of javax.persistence.parameter interface? i rather impressed how @staticmetamodel used criteriabuilder in jpa2 meaning type safety , don't have mess around setting string names. wanted apply similar of jpa1 ejb's i'm working on: dealergroup_.class: public dealergroup_ { public parameter<integer> id = new parameterimpl<integer>("id"); /// etc... } dealergroupfacade.class: // ... public dealergroup fetch(integer id) { typedquery<dealergroup> query = em.createnamedquery("dealergroup.fetchbyid", dealergroup.class); query.setparameter(dealergroup_.id, query); return query.getsingleresult(); } // ... i surprised find there no implementations of parameter interface - of course, implement myself absence makes me suspicious may mistake using in way? should implementing parameter...
