How to scrape data from an interactive chart using python?

Question

I would like to scrape the date and total value data from the "Value History" chart on the following link when the chart is set to 1Y:
https://csgoskins.gg/markets/csgofloat

I’ve tried to look and see if the data on the site is stored in a json file, but it does not seem like it.

I found this looking at the javascript code of the site, which makes me think the data is stored within a variable called t, but I haven’t been able to find it:

series: [{
                        name: "Total Value",
                        type: "line",
                        showInNavigator: !0,
                        color: "#60a5fa",
                        marker: {
                            lineColor: "#60a5fa"
                        },
                        data: t.map((function(t) {
                            return [Date.parse(t.day), t.sales_value]
                        }

Which is part of a function called: window.createMarketValueHistoryChart = function(t)

Any help would be much appreciated!

Answer 1

Check the history variable in the console. Something like:

history.forEach(v => {console.log(v.day, v.sales_value)})

will print the data you need.

Getting it to pandas

If you use Chrome (but I’d assume that should work for most browsers), in the console write history, hit enter, right-click on the output, "Copy object". Paste it into data.json file and read with:

df = pd.read_json('data.json')
