+# Polar Microphone Sensitivity
+
+![Polar Microphone Sensitivity](polarMicrophoneSensitivity.png)
+
+This demo application belongs to the set of examples for LightningChart JS, data visualization library for JavaScript.
+
+LightningChart JS is entirely GPU accelerated and performance optimized charting library for presenting massive amounts of data. It offers an easy way of creating sophisticated and interactive charts and adding them to your website or web application.
+
+The demo can be used as an example or a seed project. Local execution requires the following steps:
+
+- Make sure that relevant version of [Node.js](https://nodejs.org/en/download/) is installed
+- Open the project folder in a terminal:
+
+        npm install              # fetches dependencies
+        npm start                # builds an application and starts the development server
+
+- The application is available at *http://localhost:8080* in your browser, webpack-dev-server provides hot reload functionality.
+
+
+## Description
+
+This example showcases a simple Polar Chart with five Line Series.
+
+Polar Charts are used for visualizing data relationships in terms of radiuses and angles.
+
+## Polar coordinate system and PolarLineSeries
+
+```typescript
+{
+    // Data point angle as degrees [0, 360].
+    angle: 0,
+    // Data point position on the *Amplitude Axis*. Determines its location between the Charts origin and outer edge.
+    amplitude: 50
+}
+```
+
+*PolarLineSeries* connects a list of such *PolarPoints* with a continuous line.
+
+[//]: # "IMPORTANT: The assets will not show before README.md is built - relative path is different!"
+

+
+
+## PolarRadialAxis
+
+The coordinate system can be rotated with methods of *PolarRadialAxis**.
+
+```typescript
+// Configure Polar Radial Axis.
+const radialAxis = polar.getRadialAxis()
+    // 0 = North
+    .setRotation(90)
+    // Clockwise direction.
+    .setInverted(true)
+```
+
+## PolarAmplitudeAxis
+
+Similarly, the visible range of amplitude values can be configured with methods of *PolarAmplitudeAxis*. The default configuration is to fit 
+
+```typescript
+const amplitudeAxis = polar.getAmplitudeAxis()
+    // Set amplitude interval explicitly.
+    // [-39 dB, 0 dB]
+    .setInterval(-39, 0)
+    .setTitle('Sensitivity (dB)')
+```
