Example Function Scripts

Example scripts for the function editor.

Generating a Logarithmic Axis

To generate an exponential axis on a map or table, you could use the following script:

var power = 2;  
var m = x / (xcount - 1);  

minvalue + range * Math.pow(m, power);

Adjusting the ‘power’ variable will adjust the curvature of the resulting axis:

power = 1.5

power = 2

Display Average of All Sites

To calculate the average of all sites and display it without modifying the map , you could use the following script.

This shows some more advanced scripting features.

// Loop over all sites and calculate a rolling average  
let avg = 0;  
let n   = 0;  
let val = 0;  
for (y = 0; y < ycount; ++y) {  
    for (x = 0; y < ycount; ++y) {  
        ++n;  
        val = object.getReal(x, y);  
        avg += (val - avg) / n;  
    }  
}  

print("Average Value: " + avg.toString());  
// Terminate the script:  
completed = true;  

// Set the result so that the object is not modified.  
result = v;

This will display the average value of the map in a popup dialog box.
