General overview

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. A 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.

Description

Tabs

Move to different sections.

Graph toolbar

Actions like zoom, pan, save as image, and other settings.

Main area

Part of the window where the graph or statistics are represented.

Column filter

Filter datasets or columns.

Data tree

Datasets are shown in tree form. If checked, column data will be shown in plots.

Options

Additional options e.g. aggregations, filters.

Redraw

Redraw the current graph with the latest changes.

Component

Description

Aggregation

Aggregate data to higher time step.

Min of valid points

Minimum required number of original records (in %) for summarizing the output interval. If this condition is not met (e.g., there are less than 30 1-minute records in the hourly output interval, while we require a 50% minimum), the output interval is empty-filled by the NaN value.

Year/Month

Filter data by year, month, or year and month.

Date

Filter data by date and/or time.

Data column

If only one dataset is present, it's possible to filter data by range from any column of that dataset. If multiple datasets are present, it's possible to filter only by solar elevation.

Period of day

Filter data by period of the day, similar to filter data by solar elevation.

Flags

If checked, data are filtered by flag values from the flag column.

Valid

Check valid flags.

Select All

Check all flags.

Deselect All 

Deselect all flags.

Flag values

Dataset flags from the dataset flag scheme.

Time series

Component

Description

View in time zone

If checked, data are shown in UTC chosen.

Show values

If checked and zoomed to less than 3 months of data, show the closest values near the cursor.

Compare mode

Used to compare measured and model datasets. Time stamps must match exactly.

Harmonize on hourly aggregation

Option harmonize on hourly aggregation can be applied for time step > hourly (daily or higher aggregations).

When checked, data are aggregated to hourly aggregation, then data are filtered to match the same time stamps, and then data are aggregated to higher aggregation (Daily, Monthly, Yearly).

When unchecked, data are aggregated and only after aggregation data is filtered to match the same time stamps.

Align time stamps

When using compare mode, time stamps in both measured and model datasets must match exactly, otherwise time series plot is empty. Align time stamps interpolates measured dataset to match model dataset time stamps.

Heatmap

Component

Description

View in time zone

If checked, data are shown in UTC chosen.


Histogram

Component

Description

View in time zone

If checked, data are shown in UTC chosen.

Start at

If checked, the histogram starts at this value.

Number of bins

Set the number of bins of the histogram.

Bin size

Set the width of bins.

Compare mode

If checked, show data only with a common timestamp.

CDF

Component

Description

View in time zone

If checked, data are shown in UTC chosen.

Percentile

Show a horizontal percentage line with vertical value line in the graph.

Compare mode

If checked, show data only with a common timestamp.

Diurnal profiles

Component

Description

View in time zone

If checked, data are shown in UTC chosen.

Monthly / yearly

Show monthly or yearly diurnal profiles graphs.

Mean / median

Show mean/median diurnal profile line.

PXX

Show percentile line.

Custom

Show custom percentile line.

Compare mode

If checked, show data only with a common timestamp.

Monthly profiles

Component

Description

View in time zone

If checked, data are shown in UTC chosen.

Compare mode

If checked, show data only with a common timestamp.
