Analyze
General overview
Analyze dialog provides an extended view of data in sets of specific graphs that focus on multiyear comparison and single-column visualization.
Profiles. Yearly/monthly diurnal profiles graph
Multiyear Analysis. Comparison of years as time series, maximum GHI/DNI/GTI, maximum daily ktm
Kt Graphs. Set of graphs in Kt space. GHI, DNI and DIF columns need to be in the dataset in order to draw all graphs.
Monthly Averages. Monthly averages graph
Trends. Trend graphs with linear, polynomial or moving average trend line
Component | Description |
Dataset | Selected dataset for visualizations |
Column(s) | Selected column or set of columns for visualizations |
Options | Various options for each tab |
Aggregation | Output 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 hourly output interval, while we require 50% minimum), the output interval is empty - filled by 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 flag column |
Valid | Check valid flags |
Select All | Check all flags |
Deselect All | Deselect all flags |
Flag values | Dataset flags from dataset flag scheme |
Redraw | Redraw current graph with the latest changes. |
Options
Profiles
Component | Description |
monthly / yearly | Show monthly or yearly diurnal profiles graphs |
View in time zone | If checked, data are shown in UTC chosen |
mean / median | Show average/median diurnal profile line |
percentile | Show custom percentile line |
fill between | Fills area between custom percentiles |
Multiyear Analysis options
Component | Description |
h0 limit | Filter time steps where sun position are greater than h0 limit |
value limit | Filter time steps where column values are greater than h0 limit |
Ktm limit | Filter time steps where clearness index values are greater than Ktm limit |
Ktm std limit | Filter time steps where standard deviation of clearness index values are lower than Ktm std limit |
Kt Graphs options
Component | Description |
AOD lines |
|
Sun elevation treshold | Filter time steps where column values are lower/greater than solar elevation limit |
Trends options
Component | Description |
Min of valid records for daily averages | 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 hourly output interval, while we require 50% minimum), the output interval is empty - filled by NaN value. Used only when input is sub-hourly. |
Linear trend | Draw linear trend line |
Polynomial trend | Draw polynomial trend line of selected degree |
Smooth data | Use only full period for calculating polynomial and moving average trend lines |
Moving average | Draw moving average trend line with selected number of months |
