Hi,

I'm a Java newbie , and we got an assignment in school to program an
economic graph. The result is a circle devided in a variable number of
segments (standard : 12).

Everything is finished, the only problem is that I need to draw strings
around the circle. On the right hand side , no problem off course, but on
the left side, I would need to draw the string so that the end of the string
touches the circle.

Any suggestions on how to do this ?.

Regards ,

Oliver

You can measure the string's width for the
graphics context you render it on. This way
you can right-align it.

You can observe how I position strings in
my JDiskReport tool that you can find at:
http://www.jgoodies.com/freeware/jdiskreport/

Actually, the string positions in JDiskReport
are only the initial good guess. I could never
find the time to adjust them to better avoid
overlapping labels.

A true alternative is to render labels on both
sides and draw lines to the associated pies.

Hope this helps,
Karsten

you need to know width of your String.
Use FontMetrics.stringWidth(String);

FontMetrics(Font f).stringWidth(String s);

Hi Karsten ,

How do you measure the width of the string ?
I know you can count the number of letters ,
but how do you know how much to draw ?

    String s = xyList[i].getNaam();

   FontMetrics fm = getFontMetrics( g.getFont( ) );


   if ( xyList[i].getX() < 1 ){


    margex= fm.stringWidth( s );

   }

  the margex is the amount of pixels I move to te left, however , this
doesn't reallt work that good.

Hi Andrew ,

this is my code so far :

String s = xyList[i].getNaam();

   FontMetrics fm = getFontMetrics( g.getFont( ) );


   if ( xyList[i].getX() < 1 ){


    margex= fm.stringWidth( s );

   }


the margex is the amount of pixels I move to the left before drawing the
string, however this has a different result everytime I change the string.

the IF is used to see if the string is on the left of the circle.

Regards

Oliver

I use FontMetrics#stringWidth(String).
