    I am using the following html in Angular 2 inside wj-flex-chart tag with other properties but unable to plot any trendLine.
    <wj-flex-chart-trend-line #trendLine
    [binding]="'y'"
    [fitType]="'Linear'"
    [name]="'Linear'"
    [order]="2"
    [style]="{stroke:'darkred',strokeWidth:3}"
    [visibility]="'Visible'">
    </wj-flex-chart-trend-line>
    Using json data to plot the same.
    Wijmo Version : 5.20212.812
    Please let me know if any thing else needs to be added in the code.

    Thanks a lot for prompt reply.

    I tried everything, checked my template code, data format, ts file, modules, packages, even copied your example along with the data file. Checked every thing thoroughly, but still no trendline (not even console or JS errors)

    The only difference in my repo code and the example you shared, is Angular version. Please confirm if that is the case.
    I am using "@angular/core": "5.2.6"; and the one in example is 11.2.14
