Types of Charts

Amount of Orders by Summary Status

The summary status of the order displays the worst result among the analysis results for this order. For instance, if one of the group of analyses has finished with the DECLINED status, the order status will be DECLINED as well.

The order result receives the status of the last group of analyses applied to the folder. A group of analyses contains analyses you've sent in a single order.

Chart options:

• All Results – displays the sum of all results

• Any result – showing all results on one chart separately, except for the All results option

• Processing – results, where the analysis is in the "Processing" status

• Failed – Analysis results with the error message "Failed"

• Declined – the results of analyses, which indicate a low percentage of similarity with the reference image, or indicated inconsistencies in the fields of the document (depending on the modules)

• Success – the results of analyses, which indicate a high percentage of similarity with the reference image, or indicate the full correspondence of the document fields (depending on the modules)
