Chart Command Bars Overview

In This Topic

NOV Chart provides a lot of commands and settings most of which can be shown to the end user in a command bars interface (menu and toolbars). There are two ways to create command bars associated with a chart view:

Chart View with Command Bars Control

If you are not creating a cross-platform application, the easiest way to create a chart view with command bars is to use the Visual Studio designer and drop an NChartViewWithCommandBarsControl from the Visual Studio toolbox to your form/window.

Alternatively, you can use the NChartViewWithCommandBars class to add a chart view with command bars to your form/window programmatically. The example below demonstrates how to create a chart view with command bars hosted in a NOV widget host. You can then add this host to a form's Controls collection if you are creating a WinForms application, set it as the Content of a WPF window in a WPF application project, or to the ContentView of a Xamarin.Mac window.

NChartViewWithCommandBars chartViewWithCommandBars = new NChartViewWithCommandBars(); // Create a chart view with command bars NChartView chartViewWithCommandBars = ribbonUI.View; // Get the chart view // Create a NOV widget host that hosts the chart view with command bars NNovWidgetHost<NWidget> novHost = new NNovWidgetHost<NWidget>(chartViewWithCommandBars);

Create a chart view with command bars

Copy Code

NChartViewWithCommandBars chartViewWithCommandBars = new NChartViewWithCommandBars(); // Create a chart view with command bars
NChartView chartViewWithCommandBars = ribbonUI.View; // Get the chart view

// Create a NOV widget host that hosts the chart view with command bars
NNovWidgetHost<NWidget> novHost = new NNovWidgetHost<NWidget>(chartViewWithCommandBars);

Chart Command Bar Builder

NOV Chart provides a command bar builder that can be used to create toolbars to control and edit the chart view and its charts. This builder is represented by the class NChartCommandBarBuilder.

The following code fragment demonstrates how to create a command bar-based commanding UI using a chart command bar builder and associate it with a chart view:
