Limits in DataLens On-premises
Limits are technical constraints of the DataLens architecture. Limits cannot be changed.
General limits
Note
DataLens has no limitation on the amount of data on the source you are connecting to.
| Type of limit | Value |
|---|---|
| Maximum number of tables per dataset | 32 |
| Maximum number of fields per dataset | 1,200 |
| Maximum data size for direct chart export | 50 MB |
Chart data limits
Charts in DataLens can only display a limited amount of data. If the number of rows (columns and cells for pivot tables) in a dataset exceeds the set limit, the chart will not be built. Therefore, to build a chart from data in a large dataset, select a part of the data to display based on the limits below using filters:
| Chart type | Limit |
|---|---|
| Charts | |
| Line chart | 75,000 rows |
| Area chart Normalized area chart |
75,000 rows |
| Column chart Normalized column chart |
75,000 rows |
| Bar chart Normalized bar chart |
75,000 rows |
| Scatter chart | 75,000 rows |
| Pie chart | 1,000 rows |
| Tree chart | 1,000 rows |
| Tables | |
| Table | 100,000 rows |
| Pivot table | 100,000 cells |
| Pivot table | 800 columns |
