====Count Example: Daily Total from Totaliser====

In this example, we want to know how much our machine has produced **per day**.

While our machine gives us a 'total production' value, it resets back to zero every time someone interrupts the power - which happens several times a day.

This analytic will give us a quick and easy daily total.

To begin with, we have one [[counter_pivot|Pivot]] node named //Pivot On//, and one [[counter_totaliser|Total Output]] node named //Total//

The output node is fed from an [[ardi_point|ARDI Point]] (a point of data from the field), while the pivot is driven from a [[timing_diff|Time Difference]] node.

===Step 1: Choose the Pivot===

Our first step is to choose //what we are going to pivot on//.

Fortunately, the default should work fine here. Simply choose a date in **YYYY-MM-DD HH:MM:SS** format that you want to use as the 'base' of your day.

For example, if your official 'day' starts at 9:00AM, you might want to use that time as the basis of your days.

To set the name of the node, 

  * Right click on the top-left node, choose Title and type 'Day Number'

===Step 2: Change the Node Type===

The default counter graph includes the **Changes** node, which counts the number of times the incoming data changes. We don't want this.

We want to base our total on an existing total value. So we want to replace the Changes node with a [[counter_totaliser|Totaliser]] node.

  * Right-click on the Total node and choose 'Remove'
  * Right-click in empty space, choose 'Add', 'Count' and 'Totaliser'
  * Drag the output of the lower ARDI Point into the new node

===Step 3: Choose the Total===

Next, we need to choose //the data we want to totalise//.

In this case, there are **two** parts to this machine that each have their own power usage monitoring. Although [[module_pivot|pivot analytics]] can have more than one output, in this case we only care about the //total// power being used, so we need to add the power usage together.

  * Click on the //ARDI Point//.
  * Choose **Weight Sensor - Total Weight** as the property.

And you're done - by pressing **Save and Visualise**, you'll have a simple analytic showing the total amount of product you're producing every day.
