java - Obtain series identifiers when clicking on XYPlot's series -


i have 4 series plotted on xyplot. want obtain series id when click on xyplot (see //int seriesid = ???;). possible?

   _chartpanel.addchartmouselistener(new chartmouselistener() {         @override         public void chartmouseclicked(chartmouseevent cme)          {             mouseevent me = cme.gettrigger();             xyplot plot = (xyplot) cme.getchart().getplot();             if (me.getclickcount() == 2)             {                 plot.clearannotations();             }             else             {                 rectangle2d dataarea = _chartpanel.getscreendataarea();                 plot.clearannotations();                 valueaxis xaxis = plot.getdomainaxis();                 valueaxis yaxis = plot.getrangeaxis();                 double x = xaxis.java2dtovalue(cme.gettrigger().getx(), dataarea, rectangleedge.bottom);                 double y = yaxis.java2dtovalue(cme.gettrigger().gety(), dataarea, rectangleedge.left);                 if (!xaxis.getrange().contains(x)) {                      x = double.nan;                                    //int seriesid = ???;                  decimalformat df = new decimalformat("#.##");                 df.setroundingmode(roundingmode.ceiling);                 xypointerannotation pt = new xypointerannotation("lat: " + df.format(y) + "\n lon: " + df.format(x), x, y, 0.2);                 pt.setbackgroundpaint(new color(103,154,236));                 // pt.setarrowpaintnew color(103,154,236)d);                 pt.setfont(_font);                 pt.setpaint(color.light_gray);                 plot.addannotation(pt);             }         }

as shown here, can retrieve chartentity chartmouseevent. chartentity of type xyitementity, can dataset via getdataset() , series index via getseriesindex().

chartentity ce = cme.getentity(); if (ce instanceof xyitementity) {     xyitementity e = (xyitementity) ce;     system.out.println("dataset: " + e.getdataset());     system.out.println("series index: " + e.getseriesindex()); }

Redirect to a HTTPS version using .htaccess -

i need modify .htaccess file redirect urls https version without "www". http://example.com --> https://example.com http://www.example.com --> https://example.com https://www.example.com --> https://example.com this how .htaccess file looks like: rewriteengine on rewritecond %{request_filename} !-d rewritecond %{request_filename} !-f rewriterule ^(.*)$ redirect.php?id=$1&page=$2 [qsa,l] what modifications need make .htaccess in order forward https without "www"? it depends on doing current code. looks file called redirect trying display php page seo friendly url. think might confusing people. anyway, need , force https without www, need 1 more rule above. also second rule needs two capture groups in rewriterule test string because wanting 2 different values using $1 , $2 references. rewriteengine on #rediect www non www and/or http https --- combinations. rewritecond %{http_host} !^example\.com [nc,or] rewritecond %{https} !^...

Unlimited choices in BASH case statement -

consider simple bash snippet: case $option in 1) image=${options[0]%.tar} ;; 2) image=${options[1]%.tar} ;; 3) image=${options[2]%.tar} ;; 4) image=${options[3]%.tar} ;; *) echo "invalid option" exit 1 esac in real script numbers goes 30. makes pretty long. can somehow specify cases variable? something this: case $option in $i) image=${options[$(($i-1))]%.tar} any pointer appreciated. you can match against multiple patterns in single clause: case $option in 1|2|3: echo "$option one, 2 or three" ;; esac if still typing you, can use simple pattern matching: case $option in # following matches # - single-digit numbers 0-9 # - two-digit numbers starting either 1 or 2 # - number 30 [0-9]|[12][0-9]|30) image=${options[$(($option-1))]%.tar} ;; *) echo "invalid option" 1>&2 exit 1 esac
