Hi Roma,
Thank you for the provided sample markup and screenshot.
In general, the Chart legend is enabled by setting a value to the [name] property of the SeriesItemComponent:
<kendo-chart-series>
<kendo-chart-series-item
type="waterfall"
[gap]="2.5"
[data]="data"
[visibleInLegend]="true"
field="value"
categoryField="title"
[color]="pointColor.bind(this)"
name="foo">
</kendo-chart-series-item>
If the Waterfall chart uses 2 series and the legend is set via the suggested [name] property then the behavior would be as demonstrated in the following example:

But in your example there seems to be only one series, thus I am not sure if the Legend will be a proper solution. Instead, providing a Tooltip for each series item might be a better option.
I hope the provided information helps.
Regards,
Svetlin
