Scrape Highchart, missing data - web-scraping

Question

I've been trying to scrape a specific highchart, using console commands, something in the line off:
data = $('div#graphCont2').highcharts().series[0].data; { console.log(data)}
This code works on the following site, I retrieve all data.
test-hichart1
However, when I rework the code for the graph I intend to scrape (chart, Its the uppermost chart, APX-PSE for all X and Y entries), I miss data. It varies somehow (based on the timestamps, it seems to vary by the selected period), but I only get data from around timestamp 1562284800000 and onwards when the period is set to "all" (thus missing 2/3 of all entries).
I use this code:
data = $('div#stockchart_apx').highcharts().series[0].data; { console.log(data) }
My idea was to use a console.table to get the info I need, though I'm unsure if the table is usable past 999 entries anyway.
Does anyone have an idea of why the readout fluctuates and how I can retrieve all the information?
Thanks!
EDIT~ so, after a couple more hours, I managed to get all data by opening the graph in full-window mode. I'm unsure to where the differences originate from, but it worked. I scraped the data with:
data = $('div#stockchart_apx').highcharts().series[0].data;
const getCircularReplacer1 = () => {
const seen = new WeakSet();
return (key, value) => {
if (typeof value === "object" && value !== null) {
if (seen.has(value)) {
return;
}
seen.add(value);
}
return value;
};
};
JSON.stringify(data, getCircularReplacer1());
