Chart2 Direct Series Data Series Transparency (Static)

Overview 

Classes in the ooodev.format.chart2.direct.series.data_series.transparency module contains classes that are used to set the data series transparency of a chart.

Calls to the Chart2.style_data_series() method are used to set the data series transparency of a Chart.

Calls to the Chart2.style_data_series() and Chart2.style_data_point() methods are used to set the data series transparency of a Chart.

Setup 

Transparency 

Before formatting the chart is seen in Fig. 829.

Setting Transparency 

The ooodev.format.chart2.direct.series.data_series.transparency.Transparency class can be used to set the data series transparency of a chart.

Style Data Series 

from ooodev.format.chart2.direct.series.data_series.transparency import Transparency as SeriesTransparency
# ... other code

data_series_transparency = SeriesTransparency(value=50)
Chart2.style_data_series(chart_doc=chart_doc, styles=[data_series_transparency])

The results can bee seen in Fig. 759 and Fig. 760.

Style Data Point 

# ... other code
Chart2.style_data_point(
    chart_doc=chart_doc, series_idx=0, idx=-1, styles=[data_series_transparency]
)

The results can bee seen in Fig. 761.

Gradient Transparency 

Before formatting the chart is seen in Fig. 829.

Setting Gradient 

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

Style Data Series 

from ooodev.format.chart2.direct.series.data_series.transparency import Gradient as SeriesGradient
from ooodev.format.chart2.direct.series.data_series.transparency import IntensityRange
from ooodev.utils.data_type.angle import Angle
# ... other code

data_series_grad_transparency = SeriesGradient(
    chart_doc=chart_doc, angle=Angle(30), grad_intensity=IntensityRange(0, 100)
)
Chart2.style_data_series(chart_doc=chart_doc, styles=[data_series_grad_transparency])

The results can bee seen in Fig. 762 and Fig. 763.
