Line graph
A line graph displays the dependence of a value change on certain parameters as a polygonal chain. The values are displayed as dots and connected by line segments.
Use a line graph to show the dynamics of a change in the value of a certain data attribute.
Case example: show the change in the car traffic per hour in the period from 18:00 to 02:00:
Main features
-
The X-axis displays groups of data values. As a grouping attribute, you can select:
- Text attributes: for example, firm category, building purpose, and others.
- Numeric attributes: for example, number of reviews, building area, and others. To display data as a polygonal chain, specify the number of ranges and their limits in the Number of ranges field when creating a widget or editing it. You can set up ranges of different sizes. The specified upper limit is not included in the range.
-
The Y-axis displays aggregated values for each group. Aggregation is performed within one group or range. As an aggregation attribute, you can select:
- Number of objects: to count the number of values in a group or range.
- Numeric attributes: to count the total, mean, minimum, or maximum value of this attribute within each group using aggregation functions.
Creating a widget
-
Go to the Dashboards tab.
-
Select the required dashboard.
-
Click
icon. -
Click
icon next to the required layer and select Create widget. -
Specify the required parameters:
- Layer: data layer that is used to build a graph on the widget.
- Grouping attribute: attribute that is used to group data.
- Aggregation attribute: attribute that is used to aggregate data and calculate the values. If you want to display only the number of values, select Number of objects.
- Aggregation type: function that is used to calculate aggregation attribute values. Aggregation is performed within each group or range of data.
-
Set the remaining widget parameters if necessary.
-
Click Create.
Note
When working with the uploaded data, make sure that at least one attribute is specified in it to build a graph on the widget.
Parameters
General widget settings
Parameter |
Description |
|---|---|
| Widget name | Widget name. |
| Layer | Data layer that is used to build a graph on the widget. |
| Description | Text description of the widget. You can format the text: customize headings; make the text bold, italic, or underline the text; add a link; select the text color from the palette or specify it in RGB, HSL, or HEX format. |
| Change widget type | Click to select another widget type from the list. The configured widget parameters are saved. |
X-axis
Parameter |
Description |
|---|---|
| Grouping attribute | Attribute that is used to group data on the graph. Displayed on the X-axis. |
| Number of values | For text grouping attributes only. The number of dots that are displayed on the graph: the top 5 or top 10 values from the sample. The top values are calculated based on the aggregation attribute. |
| Show other | For text grouping attributes only. The last dot on the graph shows the sum of the last value in the top and the remaining values in the sample below this position. The top values are calculated based on the aggregation attribute. |
| Number of ranges | For numeric grouping attributes only. The number of ranges (dots) that are displayed on the graph. The available number of ranges depends on the data, the maximum number is 10. Ranges are calculated automatically, but you can set them manually by entering the required range limits. The specified upper limit is not included in the range. To add a range, click  icon. To delete a range, click  icon. To recalculate ranges after configuration, click  . |
Y-Axis
Parameter |
Description |
|---|---|
| Aggregation attribute | Number of objects or a numeric attribute that is used to aggregate data on the graph. Aggregation is performed within each group or range of data. Displayed on the Y-axis. |
| Aggregation type | Function that is used to calculate aggregation attribute values in each group or range of data:
|
Color
Parameter |
Description |
|---|---|
| Color | Selecting a color according to which elements on the graph are colored. You can select a color from the palette or specify it in HEX format. |
Legend
Parameter |
Description |
|---|---|
| Show legend | For text grouping attributes only. Shows the values of the grouping attribute and the corresponding values of the aggregation attribute. |
| Values in percentage | For text grouping attributes only. Shows the values of the aggregation attribute as a percentage. |
Appearance of the graph
Parameter |
Description |
|---|---|
| Labels | Labels of attribute values on the X and Y axes. |
| Axes | Axes on the graph. |
| Grid | Grid on the graph. |
Additional settings
Parameter |
Description |
|---|---|
| Show source | Name of the data layer and the aggregation attribute. |
| Show empty ranges | For numeric grouping attributes only. Shows on the graph the ranges of values without data. |
| Total value | The sum of the values of the aggregation attribute in the sample. |
| Mean value | The mean value of the aggregation attribute in the sample. |
| Minimum value | The minimum value of the aggregation attribute in the sample. |
| Maximum value | The maximum value of the aggregation attribute in the sample. |
| Total objects in the asset | Number of objects in the sample that is used to calculate the values. |
