Examples

Shows how to get chart series data.

doc = aw.Document()
builder = aw.DocumentBuilder()
shape = builder.insert_chart(chart_type=aw.drawing.charts.ChartType.COLUMN, width=432, height=252)
chart = shape.chart
series = chart.series[0]
min_value = 1.7976931348623157e+308
min_value_index = 0
max_value = -1.7976931348623157e+308
max_value_index = 0
i = 0
while i < series.y_values.count:
    # Clear individual format of all data points.
    # Data points and data values are one-to-one in column charts.
    series.data_points[i].clear_format()
    # Get Y value.
    y_value = series.y_values[i].double_value
    if y_value < min_value:
        min_value = y_value
        min_value_index = i
    if y_value > max_value:
        max_value = y_value
        max_value_index = i
    i += 1
# Change colors of the max and min values.
series.data_points[min_value_index].format.fill.fore_color = aspose.pydrawing.Color.red
series.data_points[max_value_index].format.fill.fore_color = aspose.pydrawing.Color.green
doc.save(file_name=ARTIFACTS_DIR + 'Charts.GetChartSeriesData.docx')
