 Pie-chart labels or not visible on Linux-64 |

Created a pie-chart using chartDir
PieChart *c = new PieChart( 220, 240 );
With some data and labels.
c->setData(
DoubleArray( &vData[ 0 ], static_cast< int > (vData.size()) ),
StringArray( &vLabels[ 0 ], static_cast< int> (vLabels.size()) ) );
Pie-chart labels are not visible on Linux-64.
On other platforms we don't have this issue.
Can you please let me know if there are any known issues related to piehcart labels on 64bit Linux.
Thanks and Regards,
Chaitanya |

Hi chaitanya,
Have you verified that you have copied the "fonts" subdirectory to the directory that contains the active "libchartdir.so.5.1.0" (or "libchartdir.so.x.x.x" where x.x.x depends on the ChartDirector version)? Windows and Mac OS X comes with fonts, but Linux, FreeBSD and Solaris may not have fonts in operating system defined locations. So for Linux, FreeBSD and Solaris, there is a "fonts" subdirectory for ChartDirector, which should contain the font files.
If the above still does not solve the problem, please try the followings font loading test:
char buffer[4096];
Chart::testFont("arial.ttf", 0, 8, 8, 0, buffer);
//display the result on the console
printf("%s\n", buffer);
Please kindly let me know what is the result. For your pie chart, you may also try to use the "Simple Pie Chart" sample code (with all data and text strings hard coded) to ensure the text strings are not empty.

Hi Peter,
After copying fonts directory to lib64 directory( where libchartdir.so is present ),
this issue got resolved.
Now labels are appearing perfectly on Linux64.
Thanks a lot for your quick help.
Best Regards,
Chaitanya |
