Dell PowerProtect DD Management Center (DDMC) 7.9 Installation and Administration Guide

Interacting with the Projection Chart

You can perform a custom projection using the interactive Projection Chart at the bottom of the Capacity > Projected page.

1. To adjust the visible range of data shown in the chart (this does not change the projected dates):
   • In the Date Range control, at the top left of the chart, simply select 1w, 1m, 3m, 1y, or All. The input fields at upper left change the visible range of data, and those on the right change the projection dates.
   • Enter specific dates in the date input fields.
   • To change the projections, you can slide or adjust the gray area in the chart. You can move these controls to the left or right, or you can make the chart wider or narrower, to fit a time range you believe is more representative than the one DDMC computed as the best fit.

   A better correlation between the projected trend line will show a narrower confidence range around the projected trend line. A less satisfactory correlation will show a wider confidence range.
2. In the Dates used for making projections control, at the top right of the chart, the dates will update to reflect the customized projection.
3. Use the Defaults button to return to the default/best fit projections.
