How to Plot a Line In a existing Bar or Line Chart

Hello,
I want to know if there is a option to plot a target line in Line Chart or Bar Chart that does not belong to the data set. I have a sample Snippet.

how do I add a line to this chart?

This can be done using other libraries like Highcharts. Please follow this snippet to see what i expect to do. I want a line like the red one in this snippet and show its value in the y-axis as well.

How can i achieve this using webix?

Hello @rumman0786 ,
Unfortunately, we don’t have such functionality. As a solution, you can integrate a Highchart and use it as a Webix component.
Please take a look at the snippet:
