Summary
pd4castr home page charts pd4castr and AEMO price forecasts as well as input data common to both forecasts. Historical rundatetimes can be included and compared for all data sets.
Model type and release date
This information is shown in both the home page and the link in DAEG. The convention follows:
Model_version: v[date][model_id]
For example: v2023.04.04A means that model_id, A, was last updated on the 4th of April 2023.

Selecting Regions
Just like DAEG and WAEG you may select any number or regions to chart pd4castr’s forecast price. Note that the colour palette is fixed for each region.
Model inputs are charted for only a single region. If multiple regions are selected then the first selected region is charted in model inputs.
The price forecast and model input region boxes are linked but you can only select multiple regions from price forecast. Try selecting different regions from both the region boxes to see how they relate.
Chart Options
Clicking “show options” will open a menu for both the price forecast and model input chart.
Deselect or select AEMO price forecasts in price forecast chart. This allows you to compare pd4castr price forecast with AEMO’s price forecast.
You may select up to four different rundatetimes to compare changes in forecasts.
Colours get progressively lighter in the order of rundatetimes selected (not in order of rundatetime).
Selecting rundatetimes applies to both price and model input charts.
When more than one rundatetime are selected only one model input is charted at a time.
Hover over 'i' symbol next to input variables to see a precise definition of input variables.

Auto refresh is ON by default and this will update the charts automatically when new data are published.

You may hold down left mouse button and drag in any direction to zoom into the area.
Reset Zoom will appear which you may click to restore chart.
