====GTHist====

The **GTHist** function is part of the [[Trigger]] class. 

It allows you to perform a simple 'greater than' comparison that includes hysteresis, to prevent your [[condition function|condition function]] from //flickering// on and off when values are near thresholds.

===Parameters===

^Name^Description^
|value|The value you want to compare|
|threshold|The threshold you want to compare against|
|span|The amount of hysteresis|

===Example===

<code>
lambda o: o.GTHist(o.Value(),200,10)
</code>

//In this example **condition function**, the value is being compared against '200'. When the value goes over 200, the output changes to True. //

//It will **continue** to output True until the value drops to 190 (the **threshold** minus the **span**)//

===Return===

The function returns **True** or **False**
