HoneycombChart
The HoneycombChart is used to display data in a grid using various shapes for
data points.A honeycomb chart organizes and presents data in a visually
structured way, making it easier for viewers to analyze and interpret
information.
Import
import { HoneycombChart } from '@dynatrace/strato-components-preview/charts';
Use cases
The HoneycombChart can compare the values of its nodes based in a string
(category) or in a number. For category-based hive a data should be provided
as a string, array of strings or objects that contain value prop as a
string. For numeric hives a data prop expects either a number, an array of
numbers or objects with numeric value prop.
Shapes
The nodes in the honeycomb can be set in 3 different shapes: 'circle',
'square' and 'hexagon'. ('hexagon' being the default one).
Chart Size
By default, the chart will use all the available container size up to a maximum
height of 300 pixels. The height of the chart can be changed by providing a
numeric value to the height prop which will be treated as amount of pixels.
Loading
The loading prop is a boolean value that can be passed to the HoneycombChart
component to control its loading state. When the loading prop is set to true,
the loading indicator appears in the middle of the chart plot to inform the user
that the component is currently fetching or processing data. When the loading
prop is set to false, the component should display its regular content.
Legend
The purpose of the legend is to provide additional identifying information for the chart, without the need to interact with it.
Position
By default, the position of the legend of the HoneycombChart is set
automatically. This option prioritizes the legend placement to the right of the
chart area. When the chart width is reduced, the legend is repositioned to the
area beneath the chart. It is also possible to explicitly set the chart's legend
position to right or bottom using legend's position prop.
Toolbar
Download data as CSV
The HoneycombChart component supports downloading data in CSV format using a
toolbar button. To enable this feature, a ChartToolbar subcomponent with
ChartToolbar.DownloadData inside of it must be provided to the
HoneycombChart component. On click of the download button, raw data will be
downloaded as a CSV file.
Placement
The placement prop can be used to set the initial placement of the toolbar
within the chart. Available options are: 'top-right', 'top-left',
'bottom-right', 'bottom-left'. Being 'top-right' the default value.
Colors
The HoneycombChart provides a set of predefined color palettes that can be
used out of the box to provide more appealing visualisations. See
Charts Colors
for more info.
Coloring a numerical dataset with predefined color scheme
The HoneycombChart is able to assign colors to the nodes based on the value
distribution of each node compared to the total. Domain will be divided in an
amount of 'groups' equal to the quantity of colors in the palette. Each node
will receive the color of the group that fits its value.
Coloring a numerical dataset using custom ranges
To define custom ranges and colors an array of objects of ColoredRange type
should be passed to the colorScheme prop.
Coloring a categorical dataset with predefined color scheme
If a categorical dataset is used, then the value of each node should be a string. A predefined color palette can be used to map the categories in the value of the node to the specific predefined color.
Coloring a categorical dataset using custom categories and color scheme
If none of the predefined color palettes fit your case, the HoneycombChart is
able to process a key-value object as colorScheme taking each key as the
category label and the value as its assigned color.
States
If the app experiences any issue like an error or an empty dataset, two mechanisms exist to deal with those situations in a graceful way.
Error state
Default
In case of an error thrown inside the chart, a predefined error message will be shown.
Custom
If you prefer to create your own error screen to preserve styles and information shown, you can create your own error state presenter.
Empty State
Default
When no data is provided to the chart, a predefined empty state message will be displayed.
Custom
An error message can be customized using HoneycombChart.ErrorState
subcomponent.
User actions
A user action is a creator-defined interaction with a given node in the hive.
Basic interactions include copying the node name and inspecting the underlying
data of it. In order to enable user actions, the ChartSeriesAction
subcomponent needs to be appended within the HoneycombChart. More
subcomponents can be added within this component, for instance the
ChartSeriesAction.Item, where custom logic can be applied.
Props
HoneycombChartProps
Signature:
export declare type HoneycombChartProps = | ;HoneycombChart.Legend

HoneycombChart.EmptyState provides a slot where the Empty state wrapper can be
set.

HoneycombChart.ErrorState provides a slot where the Error state wrapper can be
set.
ErrorStateProps
