I don’t use any special classes

          var c = document.createElement("div");   // < container for chart
          c.style.width = self.config.width + "px";
          c.style.height = self.config.height + "px";
          self.wrapper.appendChild(c);

          canvas = document.createElement("canvas");   // < --- chart itself
          canvas.id = "myChart" +self.ourID ;
          canvas.style.width = (self.config.width -10) + "px";
          canvas.style.height = self.config.height + "px";    
          canvas.style.backgroundColor=self.config.backgroundColor;
          c.appendChild(canvas);

@rafaelcota i don’t see it, but maybe there is a weird character between width and 400

so, take the space out, for both height and width

width:400,
height:800,

how big is your screen?

sdetweil

@rafaelcota great work!!..

for grins, edits the MyCovid19.js

line 168ish

          if (!self.config.stacked)
            c.style.display = 'inline-block';

comment out those two lines…

the prior module which I cloned had the ability to generate multiple charts at once,
but how that got set in your instance I have no idea…

rafaelcota

@sdetweil
This is what I’ve done so far:

I’ve deleted the spaces in height and width and numbers;
I’ve disabled ALL other modules, so this one runs alone;
I’ve commented out those two lines in MyCovid19.js

And all still the same…

It just gets the dimensions from wherever it gets them… so weird…

sdetweil

@rafaelcota but now it shouldn’t have inline-block applied, in the elements view

rafaelcota

@rafaelcota BTW, my resolution is 1920 x 1080 in an RPI 4

sdetweil

@rafaelcota and I am running this particular test on a 1920x1080 ubuntu… but my pi4 is just behind me at 3840x2160

rafaelcota

@sdetweil
It still there…
I’m sure you have better things to do than debug this with a user… I’m going to do a clean install, even if it does mean to use the brand new MM version (don’t have much installed, and have lots of time nowadays) and see what happens…

sdetweil

@rafaelcota use my installer script
see here
https://github.com/sdetweil/MagicMirror_scripts

rafaelcota

@sdetweil Thank you…

Used them… worked well.

Did a clean install, use my old config and same thing happened.
Change my config.js with original+MyCovid19 and ALL OK!

So, I changed the original config.js with my modules, one by one and ALL went OK.

So, I got curious, and then went to change the original config.js to my old one, module by module so I could find which one was interfering, and ALL went OK.

UNTIL, and this is really strange, when I change the address of localhost at the beginning, it went to the same problem again.

If I have address: “localhost”, ALL is OK
If I have address: “0.0.0.0”, then the problem appears again.

Any ideas?

Here’s my mirror working OK

and
ipWhitelist:[],

rafaelcota

@sdetweil I don’t understand how this parameters relate with the size of a graph.

I think it’s weird, at least it kept me entertained for a couple of hours in quarantine. :)

I hope you and your family and friends are OK.

sdetweil

@rafaelcota all ok here…

i have no idea really on the parms affecting… all my pi systems use address:“0.0.0.0” and ipWhitelist:[]
so I can open their pages on my pc at my desk. (easier to debug modules this way, run there , debug here)

i can only think that something in the chart.js library is trying to get a file or something and there is a cross site scripting restriction to stop it…

Yeah, 0.0.0.0 is not the IP address of your Pi. If you don’t want to use localhost, try the IP address of your Pi on your local network instead. (you can find the local IP address by entering ip address from your Pi) The Magic Mirror framework is a web server at heart, so it needs to understand what IP address it is using. You can try 127.0.0.1 as well, as that is the “local loopback” IP address. It always points to itself.

sdetweil

@bhepler no… 0.0.0.0 means listen on any/all physical network interfaces (wireless AND ethernet

127.0.0.1 means listen ONLY on the loopback interface … means ONLY apps INSIDE this same machine can access the url … (another browser for example)…
remote-control from your PC cannot connect

ip_address, means listen ONLY on the interface with that address (ie, listen on wireless or ethernet, not both)

bhepler

@sdetweil - Yeah… except 0.0.0.0 doesn’t work. So… what can you do?

I put the network IP of my pi in that field and then connect to that IP address if I’m ever on the pi itself.

sdetweil

@bhepler 0.0.0.0 works for me on multiple systems without problem

And ipWhitelist:[],

almostgithub

@rafaelcota Strange i am also having the same exact problem. My PI was also set to 0.0.0.0, however i changed it to localhost, and even tried its actual IP address as well and it did not fix it. I can change the height but not the width at all. I also tried placing it in other places on my mirror, as well as deleting the white space too

sdetweil

@almostgithub weird… I have 6 different systems running the module, ALL have address:“0.0.0.0”, ipWhiteList:[],

and I cannot reproduce the problem.

do another git pull… I just force commented out the inline-block statement that should never have been executed… see if it makes a difference

rafaelcota

@sdetweil Nope… didn’t work, it just don’t work with address 0.0.0.0, only with localhost as address…it’s really weird…
I’m using VNC to see my mirror remotely since it can’t be access from any other device… no problem for me, but my curious mind wonder how this can be.

Thank you for your time and concern,
