When new charts added no charts shown & "Charts Reload" not working

[dirkwa]

I have on my SK v2.12.0 the freeboard-sk v2.12.2 and @signalk/charts-plugin v3.0.0

when use the charts plugin with one subdir everything is fine and works as expected.
Now I added a 2nd path and no chart is shown anymore but they are available via the API.

One thing I noticed is that in the newcaledonia folder the file names are inside a '' but linux ignores that ans says it is the same file.

to exclude this I renamed all the files in that dir:

Than I clicked on the plugin again "submit" to re-read the dir. The API now shows:

But Freeboard-SK is still not showing the charts, even pushing the "Reload Charts" button when selecting a chart.

Only a "SK Server Reload" brought all the charts.

[panaaj]

Are there errors in the broswer console?... Freeboard uses the response from GET signalk/v2/api/resources/charts
If no charts are shown in the UI then there is an issue processing the response.

[dirkwa]

This is what my browser looked like when I deleted one folder in charts plugin and a) pressed submit and b) reloaded SK

So it looks like a V2 API issue.

** After SK Restart:**

[panaaj]

The charts plugin requires a restart to read new chart files and paths.

There is a PR to address this (along with some other issues)
SignalK/charts-plugin#34

You can try this as a test?

[dirkwa]

How to apply that?

[panaaj]

Download this file https://github.com/panaaj/charts-plugin/releases/download/v3.1.0-rc1/signalk-charts-plugin-3.1.0.tgz to the folder .signalk folder in your home directory.
and then on your server open a terminal...

cd ~/.signalk
npm i signalk-charts-plugin-3.1.1.tgz

[dirkwa]

You confused me a bit with v3.1.1

What I did:
wget https://github.com/panaaj/charts-plugin/releases/download/v3.1.0-rc1/signalk-charts-plugin-3.1.0.tgz
npm i signalk-charts-plugin-3.1.0.tgz

Than Restart SK

--> Everything works as expected !

[panaaj]

Ooops... sorry re the typo.

Glad that seemed to fix it.... I will seek to get the charts-plugin update released.
This version detects when new files are placed in the chart folders and makes them available to new requests...saves having to restart the plugin.
