# Quadrant Chart
> A quadrant chart is a visual representation of data that is divided into four quadrants. It is used to plot data points on a two-dimensional grid, with one variable represented on the x-axis and another variable represented on the y-axis. The quadrants are determined by dividing the chart into four equal parts based on a set of criteria that is specific to the data being analyzed. Quadrant charts are often used to identify patterns and trends in data, and to prioritize actions based on the position of data points within the chart. They are commonly used in business, marketing, and risk management, among other fields.
## Example
```mermaid-example
quadrantChart
title Reach and engagement of campaigns
x-axis Low Reach --> High Reach
y-axis Low Engagement --> High Engagement
quadrant-1 We should expand
quadrant-2 Need to promote
quadrant-3 Re-evaluate
quadrant-4 May be improved
Campaign A: [0.3, 0.6]
Campaign B: [0.45, 0.23]
Campaign C: [0.57, 0.69]
Campaign D: [0.78, 0.34]
Campaign E: [0.40, 0.34]
Campaign F: [0.35, 0.78]
```

## Syntax
> **Note**
> If there is no points available in the chart both **axis** text and **quadrant** will be rendered in the center of the respective quadrant.
> If there are points **x-axis** labels will rendered from left of the respective quadrant also they will be displayed in bottom of the chart, and **y-axis** lables will be rendered in bottom of the respective quadrant, the quadrant text will render at top of the respective quadrant.
> **Note**
> For points x and y value min value is 0 and max value is 1.
### Title
The title is a short description of the chart and it will always render on top of the chart.
#### Example
quadrantChart
title This is a sample example
### x-axis
The x-axis determine what text would be displayed in the x-axis. In x-axis there is two part **left** and **right** you can pass **both** or you can pass only **left**. The statement should start with `x-axis` then the `left axis text` followed by the delimiter `-->` then `right axis text`.
#### Example
1.`x-axis <text> --> <text>` both the left and right axis text will be rendered.
2.`x-axis <text>` only the left axis text will be rendered.
### y-axis
The y-axis determine what text would be displayed in the y-axis. In y-axis there is two part **top** and **bottom** you can pass **both** or you can pass only **bottom**. The statement should start with `y-axis` then the `bottom axis text` followed by the delimiter `-->` then `top axis text`.
#### Example
1.`y-axis <text> --> <text>` both the bottom and top axis text will be rendered.
2.`y-axis <text>` only the bottom axis text will be rendered.
### Quadrants text
The `quadrant-[1,2,3,4]` determine what text would be displayed inside the quadrants.
#### Example
1.`quadrant-1 <text>` determine what text will be rendered inside the top right quadrant.
2.`quadrant-2 <text>` determine what text will be rendered inside the top left quadrant.
3.`quadrant-3 <text>` determine what text will be rendered inside the bottom left quadrant.
4.`quadrant-4 <text>` determine what text will be rendered inside the bottom right quadrant.
### Points
Points are used to plot a circle inside the quadrantChart. The syntax is `<text>: [x, y]` here x and y value is in the range 0 - 1.
#### Example
1.`Point 1: [0.75, 0.80]` here the Point 1 will be drawn in the top right quadrant.
2.`Point 2: [0.35, 0.24]` here the Point 2 will be drawn in the bottom left quadrant.
