<h3>scale_linear() function</h3>
|
|
Transforms a given value from an input domain to an output range using linear interpolation.
|
|
|
|
<p><h4>Syntax</h4>
|
|
scale_linear(<i>val</i>,<i>domain_min</i>,<i>domain_max</i>,<i>range_min</i>,<i>range_max</i>)</p>
|
|
|
|
<p><h4>Arguments</h4>
|
|
<!-- List args for functions here-->
|
|
<i> val</i> → is a value in the input domain. The function will return a corresponding scaled value in the output range.<br>
|
|
<i> domain_min, domain_max</i> → specify the input domain, the smallest and largest values the input <i>val</i> should take.<br>
|
|
<i> range_min, range_max</i> → specify the output range, the smallest and largest values which should be output by the function.<br>
|
|
|
|
<h4>Example</h4>
|
|
<!-- Show example of function.-->
|
|
scale_linear(5,0,10,0,100) → 50<br>
|
|
scale_linear(0.2,0,1,0,360) → 72 <i>(eg, scaling a value between 0 and 1 to an angle between 0 and 360)</i><br>
|
|
scale_linear(1500,1000,10000,9,20) → 10.22 <i>(eg, scaling a population which varies between 1000 and 10000 to a font size between 9 and 20)</i><br>
