Loading diagrams in XML format

[VinuraD]

Hello! I am new to grafana as well as to this plugin. I am generating an XML content like this: in a flask server and try to retrieve that in grafana by providing my localhost url. (I have enabled the download source option). Is this method possible? However the graph is not loading and no error is displayed either.

Hi @VinuraD Welcome to grafana users ;) your xml must be begin by mxgraph, i can't see that in you model try a graph in draw.io and clieck on menu Extra > edit diagram See the xml like this example https://app.diagrams.net/?lightbox=1&highlight=0000ff&edit=_blank&layers=1&nav=1&title=Untitled%20Diagram.drawio#RtVXbjtowEP2aPLYiMddHCLSVdhErIfWyL5Wxh8SqEyPjLKFfXxsPuYJ2K%2B0iHsbHM%2BOZc8ZOQOKs%2FKrpIV0rDjKIBrwMyDKIonAYRYH7D%2FjZI5PZ0AOJFhydamAr%2FgKCA0QLweHYcjRKSSMObZCpPAdmWhjVWp3abnsl26ceaAI9YMuo7KM%2FBDepR6fRpMa%2FgUjS68nheOZ3Mnp1xk6OKeXq1IDIKiCxVsp4KytjkI68Ky8%2B7sud3aowDbl5S8DzaLV4%2BJ4MN%2FSBLmK2Xv%2FeLD9hlhcqC2wYizXnKwO27oMz2VmKnIMOyOKUCgPbA2UOP1nhLZaaTNpVaM2dKqwjf9xVAGV%2FEu3QTWFsFkAcDwdtoLzbVVhxZYcMVAZGn60LBgyRXRyvam5OtVhjhNKGTlPEKI5HUiWuGbQGkvgfhEY9QufMKH2X1SKT3oEsHA%2FCTt4j3YF8UkdhhMqty04ZozLrIN3GouIyVtLF2Wxkf%2Fk1csylSFysUR1tlBcgrq7L4H10qIhHIcJpXwhyQ4jxRwlB3j7Zewnl3L0VlgrIOZpLJunxKFibPyiF%2BdmwfzkKP49wtSyR0cvi3KIXeO%2Bl6ZBri1OFZvD6fTVUJ2BeG8O%2BWA0xRjfEuGIaJDXipV3uLYXwhCclbCPVLISz9iyQSUdk3yZGNZ%2BsTqLu7SZRJ5HnoZfoMjBV27dmyC7rl9e7198vsvoH

Hi! Thanks for replying...! So this means that even if I generate the XML content of this example (your's) locally, I should be able to generate the graph? Hence, I just copied its XML content and only changed cell-ids (pardon me for my laziness) and returned it through the server to the plugin. But the graph still not showing up and an error comes up; "Error : TypeError: Failed to fetch" Is this kind of drawing not supported or can there be any other issue ? (I have not previously come through the mxgraph format as well) I have tried it returning as a string with xml syntax as well as an XML elementtree

try get started in doc

[VinuraD]

Okay...I will be referring the docs as well. Meanwhile this is the new XML content I am trying to retrieve to the plugin, here

Hi, on the manual and repo site for the plugin (site link) you have put, "By selecting URL, flowcharting downloads xml file from url with mxgraph definition. /!\ NOT EMPLEMENTED". Does that mean this functionality is not implemented yet? Thanks

[algenty]

See configuration examples at https://play.grafana.org/d/Unu5JcjWk/flowcharting-index?orgId=1

Hi @VinuraD

You export it to XML.

uncheck compress

then output only the <mxGraphModel> content in your flask endpoint including <mxGraphModel> tag.

then customize your shapes inside <mxGraphModel> as you wish

then in grafana flowcharting choose Download Source using source type XML (note you can do this with both CSV and XML just return the right syntax. both have its perks).

this should work :)

or menu > extra > edit diagram

[CrashLaker]

omg @algenty ... i didn't know that! o.O just saved a bunch os clicks 👏

[CrashLaker]

something like this would work

[VinuraD]

@CrashLaker Thanks for reply. It was my fault at the flask server implementation that I had not implemented Cross Origin Resource Sharing (CORS), Otherwise it was the same way. So, my bad! Thanks for the support @CrashLaker and @algenty

[VinuraD]

@CrashLaker Sorry for bothering again. You mentioned that both CSV and XML can be used as source type. Could you please guide me to source/doc or any example which shows that. In my case I can only select "Source Type: XML content" from the drop down menu in grafana. Thanks!

[algenty]

CSV only available since 0.9 released yesterday

[VinuraD]

That's great. I updated and checked the same process with source type csv. However, I encountered a different issue. But will start that in another new thread. Thanks!

Hi,

still, getting an error Error : "TypeError: Failed to fetch" if I want to host my file https://example.com/example.xml any suggestion why it's happening? grafana 8.2.5

p.s

on the server side where I host XML file webserver returns status code 200 on grafana req for XML file.
