# Properties

When you want to override the default settings, you can adjust some of the module's default parameters.

## Measurement properties

Take a look at the following platform-specific code snippets to see how to change the default measurement settings for each platform. It's only necessary to provide values for non-default properties. These values should only be changed in exceptional cases.

## Platform-specific properties

{% tabs %}
{% tab title="Flutter" %}

### Graph Settings

#### graphBackgroundColor

Determines the graphBackground color. By default there is no background color

```
graphBackgroundColor: "";
```

#### drawGraph

When enabled the component draws a graph of the recorded PPG signal.

```
drawGraph: true;
```

#### lineColor

Determines the color of the graph line.

```
lineColor: "#63b3a6";
```

#### lineThickness

Determines the thickness of the graph line.

```
lineThickness: 8;
```

#### drawBackground

When enabled, the component will draw a background for the graph

```
drawBackground: true;
```

{% endtab %}

{% tab title="React Native" %}

### Styling

Add custom styling to the component. As a default, `{ flex: 1, backgroundColor: '#ffffff' }` is used.

**When customizing this, make sure to always add a&#x20;*****backgroundColor*****!**

```tsx
<RNFibriCheckView
    ...
    style = {{ flex: 1, backgroundColor: '#ffffff' }}
    ...
/>
```

### Graph Settings

#### graphBackgroundColor

Determines the color of the area under the graph. By default, this color is omitted. The backgroundColor is thus displayed under the graph.

```tsx
<RNFibriCheckView
    ...
    //graphBackgroundColor={''};
    ...
/>
```

#### drawGraph

When enabled the component draws a graph of the recorded PPG signal.

```tsx
<RNFibriCheckView
    ...
    drawGraph={true};
    ...
/>
```

#### lineColor

Determines the color of the graph line.

```tsx
<RNFibriCheckView
    ...
    lineColor={'#63b3a6'};
    ...
/>
```

#### lineThickness

Determines the thickness of the graph line.

```tsx
<RNFibriCheckView
    ...
    lineThickness={8}
    ...
/>
```

#### drawBackground

When enabled, the component will draw a background for the graph

```tsx
<RNFibriCheckView
    ...
    drawBackground={true}
    ...
/>
```
