DataViz
DataViz charts visually represent data to effectively communicate information and patterns. There are multiple charts availables like Bar, Grouped Bar, Stacked Bar, Line, and Donut. Use these charts to represent complex data in a visual format.
You can control whether to show legends, grid, tooltip, change the format of the tick labels, and change the position of the legend.
You can also customize the colors of the bars and lines.
The charts are all reponsive and adapts to the screen size seemlessly.
Usage
import React from "react"
import {
BarChart
} from "@asphalt-react/data-viz"
const data = [
{
date: "2012-05-13",
"New York": "65.3",
"San Francisco": "52.0",
Austin: "72.4",
},
{
date: "2012-05-14",
"New York": "64.2",
"San Francisco": "56.0",
Austin: "72.5",
}
]
export const BasicBarChart = ({ ...props }) => {
return (
<div style={{ width: "100%", height: "400px" }}>
<BarChart data={data} dataKey="date" />
</div>
)
}
Types
There are multiple types of data visualization components. You can use any of them as per your use-case.
- BarChart
- LineChart
- DonutChart
Responsive behavior
We set a minimum width of "312px" and a minimum height of "360px". The minimum height excludes the legends, as their wrapping behavior depends on the number of legends and available space.
All charts stretch to fit their container. Ensure you account for the legend height when defining the height of the container as the legend's height is dynamic becuse of it's wrapping behaviour.
BarChart
Bar chart which can display multiple data series, grouped, stack or side by side. Also supports both vertical and horizontal layout.
Props
data
Bar chart data.
Example:
[
{
month: "Jan",
customers: 4350,
attrition: 120
},
{
month: "Feb",
customers: 6600,
attrition: 220
}
]
To enhance the user experience, limit the number of bars to 20. In case of grouped, limit the sets to 8.
The data validation process verifies if all objects within the data array possess the identical set of keys, using the first object in the array as the reference point.
type | required | default |
---|---|---|
arrayOf | true | N/A |
colors
Colors of individual bars in a grouped or stack bar chart. Use this prop to override the default set of colors. Accepts an object with the key mapped to the key of the bar, and the value mapped to the color value.
For instance:
const data = [
{
month: "Jan",
customers: 4350,
attrition: 120
},
