2.4.1 COMPARATIVE CHART

This chart displays the trend of the power absorbed by the plant during the current day

and during the previous one, with the sample resolution defined in the VMU-C EM

(minimum 5 minutes).

The day selected for the comparison can be changed from the option panel.

VMU-Y EM

VMU-Y EM Instruction manual Version 1 14

On the abscissa axis the chart displays the hours of the day from 00:00 to 23:55, while

on the ordinate axis it displays the power in kW; the maximum ordinate value is set

automatically by an autorange function.

The chart is automatically updated every 5 minutes. Hovering the mouse cursor over the

chart area will display the relevant power value.

You can also select 3 different chart types:

- On a daily basis (DAY): the system displays the charts referring to the trend of the

current day and of the previous one.

- On a weekly basis (WEEK): the system displays the histograms referring to the

trend of the current week and of the previous one (always from Monday to

Sunday).

- On a monthly basis (MONTH): the system displays the histograms referring to the

trend of the current month and of the previous one (always from the first to the

last day of the month).

The option panel can be opened and closed through the button located in the top right

section of the “Options” bar.

Besides allowing to select one of the different available charts, the menu in question

includes a section specifying the resolution of the chart to be analysed:

- Day: Hourly display of the selected day;

- Month: Display of all the days of the selected month;

- Year: Display of all the months of the selected year.

If choosing the hourly display the user can select the time range he wishes to display,

and thus the starting and end time for the day to be analysed.

This chart includes the “Weekly” option, allowing to display a comparison between the

current and the previous week.

Note: The user cannot select the reference week, as comparing two non-continuous

week would be meaningless.

The third frame varies according to the chart the user wishes to display in some options.

All frames allow to choose the chart type:

- Line: Line chart;

- Area: Line chart with coloured area;

- Bar: Bar chart.

If the user selects the current date, a check box will be displayed at the bottom; it allows

to disable the chart automatic refresh, which is enabled by default.
