# DataLens On-premises chart settings

Charts are configurable. For example, you can choose to display a legend, customize a color scheme, or set your own title.

Available settings depend on the type of chart being configured.

## General settings {#common-settings}

General settings affect the overall display of charts.

### Axes {#axis-settings}

Axis settings are only available for charts that have at least one X or Y axis:

* Line chart.
* Area chart (stacked and normalized).
* Column chart (including normalized).
* Bar chart (including normalized).
* Scatter chart.

You can configure settings for both the **X** and **Y** axes.

{% note warning %}

Some of these settings may not be available for some axes.

{% endnote %}

* **Show**: Displays all axis elements.
* **Hide**: Hides all axis elements. ||
|| Display mode | Enables configuring continuous chart display.<br/><br/>Available values:

* **Discrete**: Plots the chart only for non-null values.
* **Continuous**: Plots the chart for all values continuously. You can only use continuous mode for the `Integer`, `Fractional number`, `Date`, or `Date and time` data types. ||
|| Axis formatting | Sets the formatting of axis labels with numeric values, date values, or date and time values.<br/><br/>Available values:

* **Auto**: Default formatting.
* **By first field on the X axis**: Displays the X axis labels with the formatting specified in the **Format** setting for the first field in the **X** section. Available in the X axis settings for numeric values.
* **By first field on the Y axis**: Displays the Y axis labels with the formatting specified in the **Format** setting for the first field in the **Y** section. Available in the Y axis settings for numeric values.
* **Manually**: Allows setting formatting parameters corresponding to field data type in the axis section. Available for numeric values, date values, or date and time values. ||
|| Grid | Enables or disables grid display on the chart.<br/><br/>Available values:

|| Scaling | Sets the chart axis scale.<br/><br/>Available values:

* **Auto**: Enables autoscaling. You can specify how DataLens sets the scale: from 0 to the maximum field value (**Autoscale from 0 to max**) or from the minimum to the maximum field values (**Autoscale from min to max**).
* **Manually**: Requires manual input of the axis scale. You can set the maximum and minimum values along the axis. DataLens will trim the chart lines by this value. ||
|#

### Colors {#color-settings}

[Generally](#color-general-settings), you can set a specific color for any graph value.

You can [create color palettes](../../operations/chart/create-palette.md) and use them in your charts.

If the **Legend** option is enabled in [common settings](#common-settings), placing this field into the **Colors** section will make the legend visible below the chart. The legend contains chart colors with text descriptions corresponding to the field values in the **Colors** section.

For [tree chart](../../visualization-ref/tree-chart.md), [table](../../visualization-ref/table-chart.md) (including a [pivot table](../../visualization-ref/pivot-table-chart.md)), the following settings are available:

#|

### Forms {#forms-settings}

This setting is only available for [line](../../visualization-ref/line-chart.md) (including as part of a [combined](../../visualization-ref/combined-chart.md) chart) and [scatter](../../visualization-ref/scatter-chart.md) charts in the [wizard](../chart/dataset-based-charts.md) and in [QL charts](../chart/ql-charts.md).

In a line chart, the setting allows you to set line shape and size, as well as line cap and junction style for a dimension or the [Measure Names](./measure-values.md) field. To configure line shapes and sizes:

1. In the top-right corner of the **Forms** section, click <!-- diplodoc:svg ![image](../../_assets/console-icons/gear.svg) --><svg xmlns="http://www.w3.org/2000/svg" width="16" height="16" fill="none" viewBox="0 0 16 16"><path fill="currentColor" fill-rule="evenodd" d="M7.199 2H8.8a.2.2 0 0 1 .2.2c0 1.808 1.958 2.939 3.524 2.034a.2.2 0 0 1 .271.073l.802 1.388a.2.2 0 0 1-.073.272c-1.566.904-1.566 3.164 0 4.069a.2.2 0 0 1 .073.271l-.802 1.388a.2.2 0 0 1-.271.073C10.958 10.863 9 11.993 9 13.8a.2.2 0 0 1-.199.2H7.2a.2.2 0 0 1-.2-.2c0-1.808-1.958-2.938-3.524-2.034a.2.2 0 0 1-.272-.073l-.8-1.388a.2.2 0 0 1 .072-.271c1.566-.905 1.566-3.165 0-4.07a.2.2 0 0 1-.073-.27l.801-1.389a.2.2 0 0 1 .272-.072C5.042 5.138 7 4.007 7 2.199c0-.11.089-.199.199-.199M5.5 2.2c0-.94.76-1.7 1.699-1.7H8.8c.94 0 1.7.76 1.7 1.7a.85.85 0 0 0 1.274.735 1.7 1.7 0 0 1 2.32.622l.802 1.388c.469.813.19 1.851-.622 2.32a.85.85 0 0 0 0 1.472 1.7 1.7 0 0 1 .622 2.32l-.802 1.388a1.7 1.7 0 0 1-2.32.622.85.85 0 0 0-1.274.735c0 .939-.76 1.7-1.699 1.7H7.2a1.7 1.7 0 0 1-1.699-1.7.85.85 0 0 0-1.274-.735 1.7 1.7 0 0 1-2.32-.622l-.802-1.388a1.7 1.7 0 0 1 .622-2.32.85.85 0 0 0 0-1.471 1.7 1.7 0 0 1-.622-2.32l.801-1.389a1.7 1.7 0 0 1 2.32-.622A.85.85 0 0 0 5.5 2.2m4 5.8a1.5 1.5 0 1 1-3 0 1.5 1.5 0 0 1 3 0M11 8a3 3 0 1 1-6 0 3 3 0 0 1 6 0" clip-rule="evenodd"/></svg> (the icon appears when you hover over the section).
1. On the **Lines** tab, specify the following for each value:
  
   * Select line thickness from the list or enter manually, from `1` to `12` pixels. If you select `Auto`, the size from the **General settings** tab or the default size will be used.
   * Select line shape from the preset values. If you select `Auto`, the shape from the **General settings** tab or the default shape will be used.

   {% cut "Line settings" %}

   ![line-chart-forms-settings](../../_assets/datalens/visualization-ref/line-chart/line-chart-forms-settings.png =439x362)

   {% endcut %}

1. In the **General settings** tab, set thickness, junction shape, and line caps for all values from the **Lines** tab.

   {% cut "General line settings" %}

   ![line-chart-forms-general-settings](../../_assets/datalens/visualization-ref/line-chart/line-chart-forms-general-settings.png =439x362)

   {% endcut %}

In the scatter chart, the setting allows you to set the shape of the dimension points by selecting it from the preset shapes.

### Labels {#sign}

Labels display measure values on the chart. [Markup functions](../../function-ref/markup-functions.md) are supported. For `String` type fields, you can configure using basic [Markdown in DataLens On-premises](../../dashboard/markdown.md) syntax: click the icon before the field name and enable **Markdown**.


Labels are available for the following charts types:

* Line chart.
* Area chart (stacked and normalized).
* Column chart (including normalized).
* Bar chart (including normalized).
* Pie chart.
* Map.

### Sorting {#sort}

Allows you to sort chart values by measure or dimension.

Sorting is available for the following chart types:

* Line chart.
* Area chart (stacked and normalized).
* Column chart (including normalized).
* Bar chart (including normalized).
* Pie chart.
* Table (including a Pivot table).

### Filters {#filter}

Filters allow you to make a selection of values by dimension or measure.
Filters are available for all chart types.


## Undoing and redoing changes in charts {#undo-redo}

When editing a chart in the wizard or a [QL chart](./ql-charts.md), you can now undo/redo any change introduced within the current [version](./versioning.md):
