... what is the actual problem, iam a beginner in primefaces and jsf...

The current syntax (5.1) is ...

<p:chart type="line" model="#{chartView.lineModel1}" style="height:300px;"/>

Check if you use latest version currently it 5.1. Visit PrimeFaces or check Maven dependency:

<dependency>
    <groupId>org.primefaces</groupId>
    <artifactId>primefaces</artifactId>
    <version>5.1</version>
</dependency>

According to the documentation of primefaces 6.2:

https://www.primefaces.org/docs/guide/primefaces_user_guide_6_2.pdf

 <p:chart type="line" model="#{bean.model}" />

These are the different types that exist, and also each one can be customized or combined several
