# It Supports
## Custom Block Number
Of course, you can also custom the **size** of blocks and **spacing** between blocks.

<img src="https://user-images.githubusercontent.com/78488529/183973081-d743c369-8f61-4c72-a211-b51183bf28f2.JPEG" width="255" height="482"> <img src="https://user-images.githubusercontent.com/78488529/183973087-22c09508-c9d1-4a77-b87c-dfbd4a4ded63.JPEG" width="255" height="482">

## Custom Block Color
Here are examples using **system colors** as below, and you can custom any color you like.

<img src="https://user-images.githubusercontent.com/78488529/183974533-5c3ae4ae-3530-458e-999a-f87a3924b185.JPEG" width="255" height="482"> <img src="https://user-images.githubusercontent.com/78488529/183974538-4e14da58-bb4e-4c6a-9c2b-61aab28d3aef.JPEG" width="255" height="482"> <img src="https://user-images.githubusercontent.com/78488529/183974546-04dd557d-5a59-42fc-bbde-4fbb0b9566ab.JPEG" width="255" height="482">

## Dark mode
Adjust to dark mode color automatically.

# Installation
Require iOS 13, macOS 10.15, watchOS 6 and Xcode 11 or higher.
In Xcode go to `File -> Swift Packages -> Add Package Dependency` 
and paste in the repo's url: 

`https://github.com/VIkill33/SwiftUI-ContributionChart.git`

Or you can download the code of this repo, then `Add Local...` in Xcode, and open the folder of the repo.

# Usage
- Import this package after you installed by `import ContributionChart`
- Use the chart like
```swift
ContributionChartView(data: yourData,
                      rows: yourRows,
                      columns: yourColumns,
                      targetValue: yourTargetValue,
                      blockColor: .green)
```
yourData is (**a double array**), and the targetValue is recommanded to set to the max value of the array.

The color of a block will appear as exactly the color as parameter `blockColor` when its value is equal to `targetValue`, and appears light gray when is equal to zero.

The top-Leading block represents the first value in array, while the bottom-trailing represents the last. And the order follows as below:
