Customizing the chart appearance

In this example, we have enhanced the appearance of our waterfall chart by customizing various elements, such as the appearance of axis elements, series, and titles.

Axis Customization

We can customize axis elements, including axis label style, major tickline style, and disabling the visibility of axis and axis major gridlines.

Series Customization

We can customize the series segment colors based on functionality using the NegativePointsBrush and SummaryPointsBrush properties. NegativePointsBrush fills the negative segments, while SummaryPointsBrush fills the summary segments. Further customization includes adding connector lines with their associated styles and integrating data labels with their respective styling properties onto the chart.

Adding a Chart Title

A chart title provides essential context to the plotted data.
