Description yeray alonso 2013-11-20 12:16:56 EST 
We used SLEAK to capture the non-disposed Resources.
1. started your Graph and keept it running for some time
2. created a snapshot from the current SWT-Resources by SLEAK
3. called chart.dispose() Method
4. Created a snapshot again and compared the differences
we found there are lot of GC objects,Font objects and color objects are existing in memory.
I think after creating new GC,old GC reference should be made null.For Color and Font It's better to access from registries.
Below stack trace is about GC object creation
at com.steema.teechart.TChart.prepareGraphics(TChart.java:1187)
at com.steema.teechart.TChart.processMouseMotionEvent(TChart.java:1225).
I think these non disposed resources will lead to performance issues.Is there any way to improve performance by disposing above objects.
