        Chart2.style_background(chart_doc=chart_doc, styles=[chart_grad, chart_bdr_line])

        wall_transparency = WallTransparency(value=40)
        Chart2.style_wall(chart_doc=chart_doc, styles=[wall_transparency])

Transparency

Before applying formatting is seen in Fig. 830.

Setting Transparency

The ooodev.format.chart2.direct.wall.transparency.Transparency class can be used to set the transparency of a chart wall and floor.

Apply to wall.

from ooodev.format.chart2.direct.wall.transparency import Transparency as WallTransparency

# ... other code
wall_transparency = WallTransparency(value=40)
Chart2.style_wall(chart_doc=chart_doc, styles=[wall_transparency])

Apply to floor.

floor_transparency = WallTransparency(value=30)
Chart2.style_floor(chart_doc=chart_doc, styles=[floor_transparency])

The results can bee seen in Fig. 723 and Fig. 724.

Setting Gradient

The ooodev.format.chart2.direct.wall.transparency.Gradient class can be used to set the gradient transparency of a chart.

Apply to wall.

from ooodev.format.chart2.direct.wall.transparency import Gradient as WallGradientTransparency
from ooodev.format.chart2.direct.wall.transparency import IntensityRange
from ooodev.utils.data_type.angle import Angle
# ... other code

wall_grad_transparent = WallGradientTransparency(
    chart_doc=chart_doc, angle=Angle(30), grad_intensity=IntensityRange(0, 100)
)
Chart2.style_wall(chart_doc=chart_doc, styles=[wall_grad_transparent])

Apply to Floor.

floor_grad_transparent = WallGradientTransparency(
    chart_doc=chart_doc, angle=Angle(120), grad_intensity=IntensityRange(0, 100)
)
Chart2.style_floor(chart_doc=chart_doc, styles=[floor_grad_transparent])

The results can bee seen in Fig. 725 and Fig. 726.
