Spielberg’s Films by “Year of Release” versus “Year Set”

The other day, over on twitter, Todd Vaziri sent a lazyweb request that piqued my interest:

free cinema chart idea

chart the films of steven spielberg and graph the release date minus the year the film takes place

you know, for fun

How does one do timelines these days anyway? I had a vague memory that Google had a tool in their charting APIs.

And they do: Timelines are a feature of Google Charts! Not too hard to set up, really. But I needed the data first. So I started a spreadsheet and started searching Wikipedia and IMDB. I added year of release, and my best guesses as to the year of setting. I also made a distinction for movies set in one period but with an epilogue or prologue in another year (e.g. Schindler’s List and Saving Private Ryan). I didn’t end up using that distinction as it didn’t have much effect on the chart.

I decided the end points would quite naturally be the average year of the setting year of the film and the year of the film’s release. Start point would be whichever was sooner. For colors I chose a shade of red (#b94e48) and for science fiction I chose a green (#8bbe1b)

I rather like the result:

My “client” responded to it favorably:

WOW!

The essence of my question was ‘how many period pictures has SS done’ and it looks like A LOT!

To work it out I used the estimable Codepen, which is terrific for working out small or medium sized web tasks. You can play with it yourself at codepen.io/artlung/pen/JjrmEgP

var futureColor = "#8bbe1b";
var pastColor = "#b94e48";
var nowColor = "#000000";
var epilogueColor = "#cccccc";
