Draw the line chart – an overview

What is it for?

Use this template to engage audiences with time series data by getting them to guess what actually happened.

How to get started

    Choose the Draw the line starting point from the template chooser.
    Next, upload your data to the template. Your dataset should have the same data structure as a line chart, with a column for the time indication and a column for each line. You don't have to add gaps to your dataset for the guessable data. This will be done in the next step. Here's what the data structure in the above example looks like:
    Year US Bottom 50% US Top 1%
    1980 20.7 10.7
    1981 20.3 11.1


    Once you've input your data, you should be able to see a preview of your chart in the bottom right corner. If you don't see a preview, you might have to change some of the column settings under "Select columns to visualise". Make sure that you add all the columns containing values relevant to your chart to the "Lines for user to guess" setting. If you'd like a line to be visible the entire time, you can add it to the "Always visible lines" setting. Here's an example of what this will look like:

    You can read more about column settings and adding your own data to a template here.
    To select how much of your line should be visible from the start, switch to the Preview tab and go to the "Guessable Lines" settings within the Lines settings. Here, you can supply what percentage of your line(s) should be visible from the start.

    You might also want to edit the text that shows up with the correct solution. To do this, go to the Text and results settings. You can replace the text and the maximum percentage of errors allowed to receive a certain score.
