Radar chart

The Radar chart (Radar chart) displays a two-dimensional chart using radial axes to chart one or more groups of values over multiple variables. Radar charts can be used to visualize and compare performance to a set standard or to a group's performance. The Radar chart is included in the Visualization bundle.

Radar charts requires two dimensions and one measure. The y-axis goes from the center to the perimeter and the x-axis is the perimeter of the chart. Each value represents the distance from the center of the chart, and displays on axes starting from the center. The center of the chart represents the minimum value, and the edge the maximum value.

A radar chart can show multiple series, each separately connected with their values. The data only goes around the chart once. Adding values only increases the chart's granularity.

Understanding a radar chart

A radar chart consists of evenly spaced segments (axes) arranged radially around a point. There is one segment for each data value of the second dimension. The value of each measure is shown by a node on applicable axis. A line connects the values that belong to the same series creating the chart’s star-like shape.

When to use it

Radar charts let you compare and measure data with an arbitrary number of variables. This is helpful when comparing something's features or performance over several metrics. For example: before buying a computer, you can compare different computers across several features, such as memory storage processing, and screen size. A radar chart is also useful when:

• Measuring quality improvements and performance.
• Comparing allocated amount versus actual spending in an organization.
• Identifying outliers, commonality, and clusters of data with similar values and features.
• Charting an athlete's strengths and weaknesses.

• Comparing results of small-to-moderate-sized multivariate data sets.

Creating a radar chart

You can create a radar chart on the sheet you are editing.

Gehen Sie folgendermaßen vor:

1. In the assets panel, open Custom objects > Visualization bundle and drag a Radar chart object to the sheet.
2. Click the top Add dimension button and select the first dimension category to be measured (x-axis).
3. Click the second Add dimension button to select the second dimension (y-axis).
4. Click the Add measure button to select the measure of the chart.

Once dimensions and measure have been selected the radar chart displays automatically (in color) in the chart field

Changing the appearance of the chart

You can customize your radar chart with one or more features.

Changing the color scheme

You can change color scheme of your chart by choosing from four predefined options.

Gehen Sie folgendermaßen vor:

1. Click Appearance > Design in the property panel.
2. Select a color scheme under Color.
   
   

Changing the stroke type

You can also customize the shape line connecting each node under Appearance > Design > Stroke type in the properties panel. Select the shape from the menu.

Toggling the legend

The legend provides a small text description of each node of the chart. The legend expands to show its text, and the chart shrinks to accommodate the legend. To toggle the legend, move the slide button under Appearance > Design > Legend in the properties panel.

Limiting dimensions

You can set limits on your dimension values. To change limitations and terms go to Data > Dimensions in the properties panel. Click dimension, and under Limitation choose a limitation from the menu.

Toggling titles

This option can hide the name of the radar chart. To toggle the name, click Appearance > General in the properties panel. Move the Show titles slide button.

Number formatting

The default setting for Number formatting for measures and dimensions is Auto. You can change this setting to Number, and then select a number format.

Using the styling panel to further customize the appearance

You have a number of styling options available under Appearance in the properties panel.

Click Styling under Appearance > Presentation to further customize the styling of the chart. Sie können Ihre Designs zurücksetzen, indem Sie auf neben den einzelnen Abschnitten klicken. Wenn Sie auf Alle zurücksetzen klicken, werden die Designs für alle verfügbaren Registerkarten im Designfenster zurückgesetzt.

Anpassen des Texts

Sie können den Text für Titel, Untertitel und Fußnoten unter Darstellung > Allgemein festlegen. Um diese Elemente auszublenden, deaktivieren Sie Titel anzeigen

Die Sichtbarkeit der verschiedenen Bezeichnungen des Diagramms hängt von den diagrammspezifischen Einstellungen und den Anzeigeoptionen der Bezeichnungen ab. Diese können im Eigenschaftsfenster konfiguriert werden.

Sie können das Design des im Diagramm angezeigten Texts ändern.

Gehen Sie folgendermaßen vor:

1. In the properties panel, expand the Appearance section.

2. Under Appearance > Presentation, click Styling.

3. Legen Sie auf der Registerkarte Allgemein die Schriftart, den Hervorhebungsstil, die Schriftgröße und die Farbe der folgenden Textelemente fest:
