The Spline Area chart allows you to showcase the difference between the minimum and maximum values over a certain time period, with data points connected by smooth curves.
To configure data for a Spline Area chart, you need at least 1 value element and 1 column element. The measure
or expression
field you want to analyze can be dropped into the Y values block. The dimension
you want to categorize the measure can be dropped onto the Columns block. If you want to categorize based on a series, then the respective dimension can be dropped onto the Rows block in addition.
Follow these steps to configure data for a Spline Area Chart:
Drag and drop the control to the canvas and resize it to your required size.
Click the Data Source
button in the configuration panel.
Click the CREATE NEW
button to launch a new connection from the connection type panel.
In the connection type panel, click any one (Here, the Microsoft Excel
Connection type is selected for demonstration) of the listed connection type button.
In the NEW DATA SOURCE
configuration panel, fill the connection type and related details. Click the Preview & Connect
button.
Drag your preferred table or view from the left pane from the data design view, and click the Save
button.
Click the Properties
button in the configuration panel, property pane opens. Now, switch to the ASSIGN DATA
tab.
The ASSIGN DATA
tab will be opened with the available measures and dimensions from the connected data source.
You can add the required data from the Measures

into the required field.
You can add more than one Measure
into the Values
field by dragging and dropping the required measure.
The configured field names can be edited by using the Rename
option provided in the settings menu.
Click the Settings
option to change the name and the required summary type from the available summary types shown in the Settings.
You can filter the data to be displayed in the funnel chart by using the Filter
option. For more details, refer to the filter.

A legend is text used to describe the plotted data. This allows you to toggle the visibility of the legend in a chart and also change the legend text position (selecting through the combo box).
Enabling the Custom Legend Text option will allow you to define custom text (through the text area) to display for each legend series (selected through the combo box) in a chart.
The chart legend interactivity
option allows you to control the behavior of the chart legends. This provides an option to make chart legends non-clickable, which can be especially useful in scenarios where you do not want users to hide or show series data by clicking on the legend. This might also be useful when displaying critical pieces of data that should always be present for accuracy and context purposes.
Enabling the Interactivity feature in the Legend Settings category allows you to click on the legends.
Enabling the Interactivity feature in the Legend Settings category allows you to click on the legends

Trim
This option allows you to trim the legend items if its legend exceeds the Text Width
value.
Wrap
This option allows you to wrap legend items based on ‘Text Width’ value.
This option allows you to set the maximum width for the Legend Items and is applicable only if text-overflow is set as Trim or Wrap.
If you uncheck the Show Legend
property in the property panel, the dependent properties, which are Legend color, Legend position, customization button, and Legend title are also hidden.
NOTE: For single series, Legend won’t be visible.
This section allows you to customize the axis settings
in a chart.
This allows you to customize the axis title color.

This allows you to enable the visibility of the Category Axis
.
If you disable the Show Category Axis
option, dependency properties, which are Show axis title, Axis title text, Trim overflow mode, Trim axis labels, Label Rotation, and Auto Interval option will be hidden.
This allows you to edit the Category Axis
title for the chart. It will reflect in the x-axis name of the chart.
If we uncheck the Show Axis Title
property, the Axis title text box property will be hidden.
This allows you to handle the display mode of the overlapping labels in the Category Axis
.
Trim

This option allows you to set a maximum width for the axis labels and it can be made customizable when the trim axis label
option is enabled.
This allows you to define the rotation angle for the category axis labels to display.
By default, the ‘Auto Interval’ property is enabled. Auto Interval property is used to set auto intervals based on a number of data points for category axis labels. If a user wants to customize the interval, then the user needs to disable the auto interval and set the required interval.
This allows you to enable the Primary Value Axis
for the chart.
If you disable the Show Primary Axis
option, dependent properties, which are Axis title, Axis title text, Axis type, and Axis Format properties will be hidden.
This allows you to edit the Primary Value Axis
title. It will reflect in the y-axis name of the chart.
By default, the chart axis shows positive values on the top and negative values at the bottom. But, there are times when we need to inverse the axis and show the negative values on the top and positive values on the bottom. For example, when we bind the temperature data to the chart and want to display the negative values on the top, we can make use of this property.
On enabling this property, the chart negative values will display on the top and positive values will display on the bottom.
This allows you to change the type of axis in a spline area chart.
Linear
This option allows you to handle the type of axis as linear.
Logarithmic
This option allows you to handle the logarithmic axis uses logarithmic scale and it is very useful in visualizing when the data has values with both lower order of magnitude (eg: 10-6) and higher order of magnitude (eg: 106).
This option allows you to format the primary and secondary axis values from the formatting details provided using the Format
button. For more details, refer to this measure format.

For more details about dashboard parameter, refer to the Dashboard parameter documentation.
A single value is stored in this type of parameter.
Click the axis range settings dialog and enter @
in any textbox (minimum, maximum, and interval). Select the parameter value (Number type parameter values only allowed).
Now the parameter value is reflected in the chart axis.
If you wish to set the same ranges in multiple cases, create the range type parameter value. This type of parameter has the start and end values.
Create a parameter in range type.
Click the axis range settings dialog and enter @
in any textbox (minimum, maximum, and interval). The range parameter is split into start and end parameters. The value in the first textbox is stored in the start parameter, and the value in the second textbox is stored in the end parameter. Select the parameter value (Number type parameter values only allowed).
The parameter value is reflected in the chart axis.
Create a parameter in the data source type. In this, choose any field. The value is based on the selected field value.
Click the axis range settings dialog and enter @ in any textbox (minimum, maximum, and interval). Select the parameter value.
