Access Data Quickly
See how Windographer 5 can simplify your life.
Analyze multiple datasets together
Instead of focusing on one dataset at a time, build a single workbook to contain all of your related datasets.
Import all kinds of data
Windographer reads virtually all data formats common to the wind power industry.
Multiple windows simultaneously
Keep your eye on multiple visualization modules while you make any modification.
Combine multiple data files
The File > Append process adds data from one or more data files to an existing data set.
Undo any modification
If you make a mistake like deleting the wrong data or executing the wrong flag rule, a multi-level undo system lets you restore your data, even days or months afterwards.
Manage larger datasets
Now a 64-bit application, Windographer 5 can handle much larger quantities of data.
Wind roses
Create many types of wind roses, including frequency by direction, mean value of any data column by direction, total wind energy by direction, and even polar scatterplots.
Import high-frequency data
Windographer 5 can read one-second data and even smaller time steps.
Flexible
New subscription model
We now offer Windographer via subscription only. This new approach means you will always have access to the latest version of software. It also frees our developers to release improvements to the software as soon as they are ready instead of holding them for the next major release. This will provide your team with the ability to continuously integrate the latest technology into your workflow.
Smart
Flag data segments based on visual inspection
By simply clicking and dragging on a time series graph or a scatter plot, you can manually apply flags to data segments to identify problems such as sensor malfunctions or icing events. Once you have applied flags, you can use those flags to filter data from graphs and calculations.
Adjustable
Measure-correlate-predict
The powerful new MCP module lets you compare and correlate with reference data, experiment with different time steps of comparison, solve for the optimal time offset, choose among several correlation algorithms, test which algorithm works best on your data, and compare your target data before and after the MCP process.
