I am trying to repeat line chart for multiple host selection. Each line chart should display the cpu usage for each selected hosts separately.

Here is my full source code in Dashboard studio.

        }
    },

            "options": {

You can try the `showSplitSeries` option in the the dashboard studio to show each line/series as it's own chart. See this runanywhere sample dashboard:

@kiran_panchavat Thanks for the quick response. Your understanding is right.

I believe your code is static , but I want dynamic according to the query results in multi select. Here's my full code
