Use a modifier to make axis values easier to read by reducing the size of very large numbers. Many EnergyPlus results are given in straight Joules or Watts, so some scale ranges can be more than 20 digits long. Applying a modifier does not change the resolution or raw data in any way, it simply applies additional numeric scaling factor.
This application is a simple 2D chart that displays detailed hourly weather and/or analysis data across the year. Use the selector bar along the bottom to choose a particular date range, which controls the main chart above to show one or more data lines or area values over that range. This chart type is particularly useful for comparing the temporal behaviour of multiple metrics.
You can load in any EnergyPlus weather data file (EPW) as well as hourly, daily or monthly EnergyPlus output files (CSV). Whilst the available metrics in each file are shown in a panel on the left-hand side of the main window, you can also select them from a sortable tabulated list by clicking the Select Display Metrics... button at the top of the panel.
In addition to EnergyPlus data, you can also load a CSV file with your own data. The format is relatively simple, requiring a single header row with titles for each data column and then either 8760/8784 rows for hourly data, 365/366 rows for daily data or 12 rows for monthly data.
The first column is always assumed to be the date/time value for that row. This value is not actually read or processed in any way as there are so many different ways to represent dates and times, so each row is assumed to contain data for each incremental hour, day or month. The only limitation on its format is that it cannot contain any commas as that will be misinterpreted as multiple columns.
All subsequent columns must contain the numeric values for each of the metrics defined in the header row. To specify the units for each metric, format its title with the name first then the units enclosed by square brackets, as shown below:
Time,Temperature[°C],Humidity[%],WindSpeed[m/s] 00:00 01-01-2018,18.5,64.2,0.23 01/01/2018 01:00,18.7,65.3,0.75 Mon 1st Jan 2018,18.6,65.6,0.16 ...
The following are some of this app's more interesting features:
The Shift and Ctrl/Meta keys are used pretty extensively to modify interactive data entry. This applies to all increment buttons, scroll wheel motion, slider controls and input elements.
NOTE: You can use the scroll wheel to edit a data value when hovering over any slider, numeric input or even table rows that indicate their editibility.
