I'm using the astrodata node and wanted to plot the sun distance values (app. 148.100.000 km) on the y axis of a line chart.
I had to divide the values by 1000 to make something happen.
I was searching the docs for some information about maximum values – to no avail.
Is 148 million too large of a number for the chart to handle? Where's the limit?
It works ok for me with big numbers
Can you show us what the messages that you are sending into the chart look like if you feed them to a debug node?
Very interesting, @Colin, thanks for caring!
The Astrodata nodes deliver their data/values directly in the msg object. For example, the sun distance is in msg.sunDistance, not in msg.payload or msg.payload.sunDistance.
When I connect a chart node directly to the output of such an astro data node and configure its y values to be msg.sunDistance I get nothing in the chart.
However, when I use a change or a function node in between and set the value of msg.payload to msg.sunDistance's value and then configure the y value in the chart node to be msg.payload it works indeed. 
So, it's not a problem with large numbers but it seems to be a problem with the chart node not being able to correctly access msg.sunDistance ...
Again, it works for me with the value in msg.sunDistance. Feed the messages into a Debug node set to Output complete message and show us what it looks like, and show us how the chart node is configured.
