Editor to share with you how to use the OxyPlot framework in Xamarin.Forms. I hope you will get something after reading this article. Let's discuss it together.

Basic course of Xamarin Chart Development (7) using OxyPlot Framework in OxyPlot Framework Xamarin.Forms

In Xamarin. The following steps are required to implement chart display on the Forms platform:

1. Add OxyPlot.Xamarin.Forms component

Open the Xamarin.Forms project and add the OxyPlot.Xamarin.Forms component to the incoming item of each subproject through Nuget.

two。 Initialize the OxyPlot renderer

Initialize the OxyPlot renderer under the subprojects of each platform. Its grammatical form is as follows:

OxyPlot.Xamarin.Forms.Platform.assignPlatform.PlotViewRenderer.Init ()

Where assignPlatform specifies the platform corresponding to each sub-project. If it is an Android sub-project, the assignPlatform here is Android.

3. Create a PlotView view

There are two ways to create a PlotView view, in the layout file xaml and in the code file .cs. These two creation methods are explained below.

(1) in the layout file xaml file, the syntax for creating a PlotView view is as follows:

Note: when laying out the PlotView view, you need to declare the namespace as follows:

Xmlns:oxy= "clr-namespace:OxyPlot.Xamarin.Forms;assembly=OxyPlot.Xamarin.Forms"

(2) in the code file .cs, you can also create a PlotView view and need to add the view to the contents of the main page.

4. Build a chart

Use the PlotModel class to build a chart, which is called a chart model. Developers can think of it as a canvas for drawing diagrams. You can add axes and data columns to the canvas as needed, that is, to achieve painting.

5. Show chart

Set the display mode Mode of the PlotView view to the PlotModel object, which sets what the PlotView view needs to display. In this way, the display of the chart can be completed.
