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/eu-token-prices.csv
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.

Deexgnome,

I’ll take a look at that CSV today probably when I have a moment and see if I can identify what might be wrong. In the meantime did you take a look at the docs?

Hey mvanderhorst,

The exporting.js bit is only used in the admin panel where the chart gets converted into a high res PNG automatically. That PNG is then attached to the post and saved into the Media section of WordPress. If you wanted to include it in the front end you’d need to do that yourself and then filter the chart options to have the export feature turned on.

Thanks, yes, I realized how stupid my question was anyway about 5 minutes after I asked it. I did get it to work within a plugin which I like because I didn’t want to dirty up the template that much but either way I was making it out to be more complicated than it really was.
