java - JFreeChart multiple tooltips along x-axis -


i have added tooltips line chart using standardxytooltipgenerator.

final xylineandshaperenderer renderer = new xylineandshaperenderer(); plot.setrenderer(renderer); renderer.setbasetooltipgenerator(new standardxytooltipgenerator());

it works well, need move cursor precise point show tooltip. hope can plotly tooltips of series shown along x-axis.

assuming chartfactory.createxylinechart(), can enable tooltips setting tooltips parameter true. note how factory's source resembles fragment.

once enabled, may let renderer make corresponding shapes visible:

final xyplot plot = (xyplot) chart.getplot(); xylineandshaperenderer r = (xylineandshaperenderer) plot.getrenderer(); r.setbaseshapesvisible(true);

in cases, may want enlarge shapes:

r.setseriesshape(0, shapeutilities.createtranslatedshape(     new rectangle(12, 12), -6, -6));

a complete example shown here. note chartmouselistener can respond axisentity, too.

you can selectively change shape, shown here. can access displayed tooltip, shown here.

arrays - What causes a java.lang.ArrayIndexOutOfBoundsException and how do I prevent it? -

what arrayindexoutofboundsexception mean , how rid of it? here code sample triggers exception: string[] name = {"tom", "dick", "harry"}; for(int = 0; i<=name.length; i++) { system.out.print(name[i] +'\n'); } your first port of call should documentation explains reasonably clearly: thrown indicate array has been accessed illegal index. index either negative or greater or equal size of array. so example: int[] array = new int[5]; int boom = array[10]; // throws exception as how avoid it... um, don't that. careful array indexes. one problem people run thinking arrays 1-indexed, e.g. int[] array = new int[5]; // ... populate array here ... (int index = 1; index <= array.length; index++) { system.out.println(array[index]); } that miss out first element (index 0) , throw exception when index 5. valid indexes here 0-4 inclusive. correct, idiomatic for statement here be: for (int index = 0; index <...
