Strange behavior setting the alignment of axis labels with Aspose.Cells 6.0.0.0
chart.CategoryAxis.TickLabels.RotationAngle = -45
results in an Excel sheet with properties showing a rotation of +45 degrees on axis labels. The effect is the same as setting a +45 value in Excel directly. Text begins at top left and slants to bottom right.
chart.CategoryAxis.TickLabels.RotationAngle = 45
results in -45 in Excel. Text from bottom left to top right.
