Variables

The Business Input Data Source supports dashboard and global variables in the String fields.

Three types of variables are discussed in the Grafana Crash Course.

Code Editor

Create new custom variable:

2022-02-10T00:00:00.000Z,
2022-03-10T00:00:00.000Z,
2022-04-10T00:00:00.000Z

Create another variable related to the first variable using the Business Input Data Source and Code editor variable type Query. Query options -> Data source -> Static.
Take the value of the from variable and add 7 days to it for each iteration.
Use ${variable_name} syntax to use your variable in code.

Code

const array = Array.from({ length: 3 }, (v, i) => `${i + 1}`);

const result = {
  ...frame,
  fields: frame.fields.map((field) => ({
    ...field,
    values: array.map((item) => {
      const currentFrom = `${from}`;
      const date = new Date(currentFrom);
      const newTo = new Date(date.getTime() + item * 7 * 24 * 60 * 60 * 1000);
      return newTo.toISOString();
    }),
  })),
};

return Promise.resolve(result);

Values for to variable will be:

2022-02-17T00:00:00.000Z
2022-02-24T00:00:00.000Z
2022-03-03T00:00:00.000Z

Now every change value for variable from change values and for variable to:

Change of From variable will update variable To.
