Profile Chart

Parent Previous Next

Tick any of the parameters listed in the left hand column to include their recorded profile in the chart.  Up to eight circuits can be displayed at once.

See Colours Used in Charts for an explanation of the colours used.

Click the ZOOM button for a description of the mouse operations to zoom in, undo zoom and scroll.

When data selected is "(Periods)" this is the point by point display of the actual data recorded in the logger.

When the data selected is "(Days)", "(Weeks)" or "(Months)" this represents the sum of the data points over the selected period.

So, for example, if a survey was recorded at an interval of 30 minutes then a Profile Chart (Periods) over 24 hours (one full day) would have 48 data points on the chart.  If the Profile Chart was selected as Profile Chart (Days) there would only be one point plotted and that would be either the same as the DAILY USAGE REPORT for kWh (or other accumulated variables) or the daily average for non-accumulated variables such as Voltage and Frequency.

Create Chart Report (Export to PDF etc)

This will create a report of all recorded data, based on the current chart view.

A report will be created with one page for each X duration of data recorded, where X is the length of data displayed on the current chart.

So, if you are viewing "Day (Periods)", you will see a report with a page for each day of data recorded.

NOTE: If you have History Compare active then the report will be a single page showing the current comparison. It is assumed that the specific view and date offset is of particular significance.


When checked displays the chart lines as 3D ribbons.


When in 3D places the ribbons in the same plane, which means they may overlap.

Separate Axes

Assigns each circuit with its own vertical axis, thus separating the chart into multiple horizontal bands.

Auto Scale

By default the vertical scale used is calculated using the highest and lowest values in all the recorded data for each circuit displayed.  If this option is ticked then only the data currently displayed is used, potentially giving much better detail if you are viewing a section of data with lower than average values.


The compare function is turned on & off via the "Compare History"/"Hide Compare" button.  As soon as you click the "Compare History" button it changes to "Hide Compare", so you can return to the standard data view.

When you first turn on the compare view the most obvious change is the addition of an extra bar of buttons below the chart, these are explained below.

"Compare Dates" Button

The default viewing option.  This lets you compare one or more dates in the currently loaded file with a different date or date range in the same file.

"Compare Files" Button

Allows you to compare data in the currently loaded file with data in a different file.  Only the circuit names which are common to both files will be available for viewing.

Navigation Buttons

Another set of video style control buttons in blue appear.  These behave exactly like the black set below them, except that they move the compare data instead of the "current" data.

"Link Controls" Check Box

When this option is checked clicking on any of the blue or black video buttons will behave as if you had also clicked the matching button in the other colour.  For example, clicking on the first of the blue buttons (showing a vertical line followed by three left-facing arrows) will move the compare data back to the start of the recorded data - when the "Link Controls" option is selected it will also move the "current" data back to it's first reading.
