# Limits in DataLens On-premises



<!-- source: en/_includes/datalens/datalens-limits.md -->
_Limits_ are technical constraints of the DataLens architecture. Limits cannot be changed.

#### General limits {#datalens-common-limits}



{% note info %}

DataLens has no limitation on the amount of data on the source you are connecting to.

{% endnote %}


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 {#datalens-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](../dataset/settings.md#default-filters):

Chart type | Limit
----- | -----
**Charts** |
Line chart | 75,000 rows
Area chart<br/>Normalized area chart | 75,000 rows
Column chart<br/>Normalized column chart | 75,000 rows
Bar chart<br/>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
