Data Reset on Specific Chart

[mcgrizzz]

The data on one of my charts is being reset every couple of hours it seems. It will start with saying there's no data to display, then collect new data.

Is this part of the design ? This specific chart, "Recipes Crafted", deals with larger numbers than the other custom chart, maybe that's where the issue lies.

Here is the code for my chart generation.

What are you trying to achieve? The total amount? Pie charts only keep the value of the last 30 minutes. It has no history.
