I’m using Aspose.Cells for Java 2.2.1.
It seems that data labels are aligned too close to the bars in the chart type BAR_CLUSTERED.
Please see labels.JPG for the erroneus chart, and and labels.xls for the correct chart (“Diagrammi 3”).
We found the issue (with the chart image) after an initial test using your template.
We will figure it out soon.
We have logged your issue into our issue tracking system with an issue id: CELLSJAVA-16836.
We have fixed the issue of data label’s position. Please try the attached version.
Works perfectly with the new version. Thanks!
