 Problem with formatted axis label |

Hi,
I've experienced this kind of issue when i use the method SetLabelFormat on an axis.
I set the label format by calling :
yAxis()->setLabelFormat("{value|g}");
The zero value is represented by the value 9.714e-17 on my Y axis (attached file LabelFormat.png)
I tried to change the label format, but no way to see the 0 value on th Y axis.
Thanks for your help.
Regards,
Herv

Hi Herv?,
This is a known issue in ChartDirector. It may happen if the axis contain negative numbers, and the label format is {value|g}.
This problem is fixed in the next version of ChartDirector, to be released within a few days. If you are using ChartDirector for C++ on Windows, you may try the release candidate for "ChartDirector for C++ Ver 5.0 for Windows". This should solve the problem.

If you do not want to try the release candidate, a method to work around the problem is to add the line:
c->yAxis()->addMark(0, -1, "0")->setMarkColor(Chart::Transparent, 0x000000, 0x000000);
Hope this can help.
