Note:
SPosi
will try to retrieve time zone offset information automatically. However, some browsers do not support this function and the time zone offset will have to be entered manually. The time zone offset is the number of hours ahead or behind Coordinated Universal Time (UTC). The offset is positive for time zones ahead of UTC and negative for timezones behind UTC. Offset information is widely available and can be found easily on the web.

Step 5


To download the Sun path data for a Sun path diagram click "Download data (csv/xls)".
SPosi
will try and create an Excel file but depending on your browser this function may not be available. If this is the case
SPosi
will produce the data in CSV format. To access the information in Excel copy the data to Notepad and save the file with "data.csv" as the filename. The file can now be opened in Excel.

To download the Sun path diagram as an image click "Download image (png)".
SPosi
will then open a new window with the image. To save the image right-click on the image and select "Save image as...".

Advanced options

Time zone offset override


The time zone offset override manually sets the time zone offset for the next plot. To override the offset simply enter the offset into the textbox and click "Override". Then click "Plot chart" to plot the chart with the new time zone offset. The time zone offset is the number of hours ahead or behind Coordinated Universal Time (UTC). The offset is positive for time zones ahead of UTC and negative for timezones behind UTC. Offset information is widely available and can be found easily on the web.

The time zone offset override can also be used to adjust for daylight saving time (DST). To plot the chart using the DST time zone offset simply add the number of hours that are adjusted during DST to the time zone offset and use the time zone offset override to manually set the time zone. Click "Plot chart" to plot the chart with the new time zone offset.
