What day are you graphing?
Upload the daily log file from GT-View or SG-View:
The log should contain data at one minute intervals. If there are intervals larger than one minute, then values will be interpolated.
If you have large gaps in your log, such as from a power outage, then we recommend you manually add rows to your log to fill in the missing space. Put the correct time on each row and use zeros for all the values. This will produce a visual gap in the graph to represent the missing data during that time. Then you can use the "partial data" option below to indicate that the log is missing information.
This log contains:
Weather forecast for this day:

Size of the graph:
The default size will fill most of the screen at a 1024 x 768 resolution. If you want to show the graphs on a higher resolution screen, make them larger. If you are going to print the graphs, make them really big. The maximum size should print at high quality on letter size or A4 paper.
You may also want to alter the size due to the nature of your data and the scales you are using, so that your graphs are not squished too much in one dimension or the other (if you have few hours of sunlight, you will probably want a narrow graph, for example).
Maximum Watt Hours for the right vertical scale:
Watt hours are used to show the cumulative total power generated over the course of the day, and are displayed on the right side of the graph.
Maximum Watts for the left vertical scale:
Watts are used to show the instantaneous power output throughout the day, and are displayed on the left side of the graph.
Start and End Times for the horizontal scale:
About the scales:
If you are making a series of graphs, you should set the same scales for all of them so that the graphs can be compared more easily.
To easily compare graphs visually across the entire year, set a Maximum Watt Hours value slightly higher than the maximum total daily power output of your inverter, set a Maximum Watts value slightly higher than the maximum instantaneous power output of your inverter, and set Start and End Times that match sunrise and sunset on the summer solistice at your location.

What kinds of graphs can you make?
Right now, you can only make graphs of the daily energy production from a solar power array. Monthly and other types of logs may be possible in the future. If you want to help add other kinds of graphs, you can get involved in the project on GitHub.
Can you graph data from other systems besides Xantrex GT Inverters?
Not right now, but the software is designed to accept other inputs. If you want to help make it aware of other data sources, you can get involved in the project on GitHub.
