Cost Charts

In most cases you'll see cost charts in the Details tab of an Element Explorer.  Cost Charts only appear for the following Element types:

These charts are intended to provide a visual overview of the components that contribute to making up the cost of delivering the element.  While the data shown varies by Element Type, they are generally the same.  The following points might help when interpreting these char

  • There may be many Elements that contribute towards the one being looked at.  Only those that have operating costs are shown.
  • Not all series in the chart go for the entire length of the chart.  This is because some elements underneath are only valid in the model for a pariod of time.  Consider an application (CHRIS21, shown) that has two implementations.  One is on-premises and the other in the public cloud.  You can see here that there's a clear date when one stops and the other begins.  This is where we see new series and an overall jump in cost.
  • Look at the Timeline for this Element too.  It will show an overview of where the contributing components come in and out of the model for this Element.
  • You might sometimes see the graph drop to zero or disappear after or before a date.  This is because the Element isn't in the model yet or is retired in this Scenario or has perhaps been Tombstoned.
  • If you change the active Scenario in the scenario chooser in the top toolbar you may see this chart change since different Elements are now being considered.

You'll notice several elements here that are interesting.  These charts are generally intended to be used within a web browser so they have a series of interactive elements:

  • Legend.  The right hand side of the chart shows the legend.  When there are several elements in the model you'll see that there is a scroller in place.
  • Trend Line.  A light blue trend line shows the overall direction of the costs.  In this case it shows that there is a steep increase in the cost of delivery of CHRIS21 over time.
  • Amortised Capital Costs.  This is the share of all the underlying capital costs associated with this piece of equipment (dashed red line)
