Large CSV File no image

So I had a moment and took a look at your file. First that’s a huge number of data points and you WILL run into Highcharts having a bit of an issue displaying a data set that that large in an optimal manner. And the plugin might be a little slow

That said you can get it to work but you’ll need to understand how M Chart and Highcharts expects the data.

A few notes:
The Region column isn’t something that lends itself well to a chart since it’s not a chartable value it’s more of a label. If Region is an important thing to include I’d do a chart per region. North American WoW Token Prices, EU WoW Token Prices, Etc…

OR you could orient the data by region. (i.e. a column for each region with the prices underneath and the dates on the other axis.

Finally M Chart expects the first cell to be empty in data sets with multiple sets of values. That’s how it tells you’ve got multiple columns of data with labels on both axis. That would allow you to graph the different regions together but that only works well if you can match up the dates, i.e. you have a data point for each date.

With this data set I’d still fall back on doing this with a chart per region especially since your date/time values don’t match up with each other from region to region.

So that leaves you with three charts like so:

https://methnen.com/misc/wow-token-csvs/north-america-token-prices.csv

Highcharts will be able to graph them a bit better too since they’re much smaller on their own.

Marking this as resolved since there’s been no response from the original poster.
