# Create a line chart of time series data

#### Step 1: Check the dtype

Make sure that dtpye of your time series data is properly recognized as `datetime` by looking at the dtype indicator in the column header.

If the dtype indicator does not say "date", see our [reference guide](/how-to/type-changes.md) for converting the dtype of a column and convert the column to a `datetime`.

#### Step 2: Create a new graph

To create a new graph, click on the `Graph` button in the Mito toolbar.

#### Step 3: Select the correct data

Set the sheet you want to graph as the graph's `Data Source`.

#### Step 4: Select the line chart

Set the chart type to `line`.

#### Step 5: Add data to your graph

Add data to the X and Y axis by clicking the `+ Add` button and selecting the column header of the data you want to add.

In this example, I'm going to add my time series data, the column called Date, to the X axis, and I'm going to add the daily high Tesla stock price to my Y axis.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.trymito.io/how-to-1/create-a-line-chart-of-time-series-data.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
