MatPlotlib errors

Hi,

Setting everything up on a new machine in a new house so gradually replicating what I had on my old set-up. That included weather charts from Matplotlib and Fantastic Weather. However, I am getting this error:

Matplotlib Error [Hourly forecast chart] Error type: invalid literal for int() with base 10: ''
Matplotlib Error [Hourly forecast chart] error producing chart. See logs for more information.

Any simple fix?

There's not enough here to diagnose the problem, but I can say that I'm not getting similar errors on either server.

1. Do you have a fully-configured Fantastic Weather Plugin *and* and fully-configured Hourly Forecast Device set up?
2. Is the Fantastic Weather Hourly Forecast Device populated with valid data in its states?

The error is saying that the Matplotlib Plugin can't convert the target Hourly Forecast state (which is an empty string) to an integer.

I think the answer to both questions is yes.

Here is more from the log...

Okay, we're zeroing in on it. Within the Matplotlib Chart Device, what is the setting for the 'Y Axis Precision'?

Also, what version of the plugin and what version of Indigo are you running?

Solved it with the Y1 formatting menu. Thanks for your help and sorry for having been a total muppet... Had missed that menu.

It's not your fault. The plugin is a victim of its customizability. There are so many settings that I had to break them into groups to make them somewhat manageable. :D

Glad you were able to sort it out.

Sorry to hear that you're having trouble. Indigo 2022.1 ships with numpy v1.22.3 (v1.16.6 for Python 2.7), which is installed with lots of other Python 3 packages, and should be available on your system. I'm running Catalina 10.15.7 on my server and the Matplotlib plugin runs fine. Indigo supports Sierra 10.12, so that should not be an issue. The Matplotlib plugin doesn't ship with any additional Python packages and it should work on your system. My first recommendation would be to re-run the Indigo installer to make sure that all the needed Python packages are installed in their proper locations. Do you have any other instances of Python installed on this machine (other than the ones that ship with Indigo?)
