 The library that implements a model of a 2D plot with support for displaying functions of time (as in an oscilloscope).
 
+_**Disclaimer:** this library was written directly on an Android smartphone with the [QLua](https://play.google.com/store/apps/details?id=com.quseit.qlua5pro2) IDE._

 - models:
   - 2D plot:
     - storing:
       - values of a displayed function;
-      - limits for these values;
+      - a `Range` from the [luamath](https://github.com/thewizardplusplus/luamath) library with limits for these values;
       - default value;
     - operations:
       - initializing:
         - filling a specified count of values by a specified default value;
-      - iterating over values:
+      - iterating over points represented as `Vector2D(index, value)` from the [luamath](https://github.com/thewizardplusplus/luamath) library:
         - via the `__ipairs` metamethod (for Lua 5.2);
         - via the `__index` metamethod (for Lua 5.3+):
           - support of fractional indexes;
