 Curve is a way to define output value from a pre-defined pair table of a discrete set of known data points. Such as standard or desired value.
-It can be represented as a black-box, where is some **INPUT x** have corresponding **OUTPUT y** = f(x)
+Curve can be represented as a function f, which is a blackbox, where is some **INPUT x** have corresponding **OUTPUT y** = f(x)
 Curve is using a piecewise linear interpolation, is a curve fitting which is a allow to using linear polynomials to construct new data points within the range of a discrete set of known data points.

 At the end, when all the rest of parameters set let's look at the result . In our example it would more precise approximation of sin(x) with 7 point defined\\

+=====Select a curve to put in register=====
+<del>First, to get value from curve you need the curves and the register pre-created.</del>
+To get the value you need:
+  - Have a curve
+  - Have a string register for dashboard element to put selected curve in it
+  - Optionally, have yet another string register for store that curve all the time
+Now, it is time to create a register with value type "String" for dashboard element.
+Then, create a new dashboard.
+{{ :curve:no_dashb.png?direct&600 |}}
+Click the "Add dashboard".
+{{ :curve:dash.png?direct&600 |}}
+Type in the Title and go on.
+{{ :curve:dash_vis_editor.png?direct&600 |}}
+Go to a visual editor.
+To do this, there is a dashboard element "Curve".
+{{ :curve:dash_element.png?direct&600 |}}
+Drag'n'drop it to create a new one.
+{{ :curve:dash_element_created.png?direct&600 |}}
+Pick a register to be used later in Lua script to get value.
+{{ :curve:dash_element_reg.png?direct&600 |}}
+Let's test it.
+Now, you need to put the curve to string register via dashboard.
+{{ :curve:dash_element_view_no_select.png?direct&600 |}}
+Click and select the one you want to pick. There is a icon for open curve editor.
+{{ :curve:dash_element_view_selector.png?direct&600 |}}
+There is a picked one.
+{{ :curve:dash_element_view_curve_1.png?direct&600 |}}
+ Let's check the register.
