Variables

The Business Input data source supports dashboard and global variables in String fields.

The Grafana Crash Course discusses three types of variables.

Code editor

To get started, create a new custom variable:

js Copy

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

1. Create another variable that relates to the first variable. Use the Business Input Data Source and set the variable type to Query with the Code editor.
2. In Query options, set the Data source to Static.
3. In the code, take the value of the from variable and add 7 days to it for each iteration.
4. Use the ${variable_name} syntax to reference your variable in code.

Code

js Copy

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);

The to variable will have the following values:

js Copy

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

When you change the value of the from variable, the values of the to variable also change:

Manual editor

You can use variables in the Manual editor. Use the $variable_name syntax in the input field.
