Time series
Basic data visualizations for multiple datasets/columns with various display options. The content of this section is distributed across the following tabs:
Time Series. Time series graph of selected data. It is also possible to draw theoretical profiles for the parameters GHI, DNI and GTI.
Heatmap. Heatmap plot of selected data. Maximum of (first) four selected columns is allowed.
Histogram. Histogram plot.
CDF. Cumulative distribution plot.
Diurnal Profiles. Yearly/monthly diurnal profiles graph
Monthly averages. Monthly averages graph
Statistics. Table with basic statistics for each column.

Compare
Tool for visualizing and statistics of two columns over concurrent time period. This feature provides a set of plots and tools divided across these tabs:
Scatterplot. Graphs of scatter plots, histogram and cumulative distribution graph.
Monthly Scatterplot. Monthly scatterplot
Time Series. Graphs of reference data, estimate data and differences between them
Heatmap. Heatmap plot of reference data, estimate data and difference between them
Analytical plot. Specific analytical graphs
Compare window has few default options when opened that can be changed. Double-clicking on graphs in the Scatterplot or Analytical plots tab will maximize the graph.
