S-Curve & Histogram

An S-Curve plots cumulative progress over time; the period histogram shows how much work falls in each period. Schedule Pro draws both from your schedule — planned, actual, and forecast — sharing one cut-off date and one set of units so periodic and cumulative views read together.

S-Curve — abilities & formatting

Planned, actual & forecast curves

Three cumulative curves on one chart make schedule performance obvious: where actual sits against plan, and where the forecast lands.

How: curves are computed from the schedule; toggle each series and set its color in the Format pane.

Configurable cut-off date

Set the cut-off (data date) that separates actual from forecast. The project default is highlighted in the selection list.

How: open the cut-off selector and pick a date; the curves split at that point.

Selectable axes

Show the value axis in units or as a percent of total, whichever suits the audience.

How: Format pane → S-Curve → axis mode (units / percent).
assets/scurve-labels.png

Data labels

Per-point values can sit on the curves; labels are on by default so the chart reads without hovering.

How: Format pane → S-Curve → data labels to toggle and format them.

Date formatting

Format the time axis to match your reporting calendar and locale.

How: Format pane → S-Curve → date format.

WBS filter

Focus the curve on part of the programme by filtering to selected WBS branches, with a searchable picker for large structures.

How: open the WBS filter, search, and select the branches to include.

Legend

A clear legend identifies the planned, actual, and forecast series and any histogram bars.

How: Format pane → S-Curve → legend position and visibility.

Histogram — abilities & formatting

assets/histogram-bars.png

Per-period bars

Each period’s workload draws as a bar, turning the schedule into a clear distribution of effort over time, paired beneath the S-Curve.

How: bars are computed from the schedule across the chosen period grouping.
assets/histogram-series.png

Planned, actual & forecast series

Compare planned against actual and forecast for each period to spot over- and under-runs early.

How: Format pane → Histogram → toggle each series and set its color.
assets/histogram-cutoff.png

Shared cut-off date

The histogram uses the same cut-off as the S-Curve, so actual and forecast bars split at the same data date.

How: set the cut-off once; both charts follow it.
assets/histogram-grouping.png

Period grouping & axis units

Group by the period that fits the programme and show bar values in units or percent, matching the S-Curve axis.

How: Format pane → Histogram → period grouping and axis units.
assets/histogram-labels.png

Data labels

Per-bar values can sit on the histogram so figures read directly off the chart.

How: Format pane → Histogram → data labels.
