[schmo90]

Hy i also have troubles with the real time chart.

it shows the chart only for 0,5s and then it will disapear?

do you ever had this issue?

and is it possible to ad more ticks on the x-axis?
if i display temp data from a day, it will only show two ticks

Good day all,
i’m able to see my data locally on my php file, but unfortunately i cannot see the graph on my MM page…

This is what i see when i open my index.php file:

This is the config file:

And this is what i see in my MM page:

Any suggestion? Consider that i’m not an expert…

Thanks.

I have the issue that the graph is jumping back to the beginning.

Has anyone else this issue?

@zazzo hm strange your data looks code…

[schmo90]

Hy i solved the issue with jumping values.

you are deleting the y axis values in the file mmm-chart.js

but not the label dataarray.

i added the line:
this.chartData.labels = [];
at #296 and now i have fixed the jumping value issue

i also added the suggestedMin/Max parameter and to change the line chart to a stepped line chart

@logen563 Hi. I am interested how you did this? Would like to display graph. Data is from an xml file that I download daily.

[schmo90]

@ricq you have to convert the xml to the json format.

i have now build a python script which provides the data from my sensors.

or you build a php script…

How do i turn my MQTT temperature data from Mosquito into jason data providing me with a url for this module? or is there a way to get your module to read an mqtt topic?

@zazzo how did you create that php file in the first place? I’m new to this and really struggling. thanks in advance

@turntablist2 u can use any language u like. I created a conversion script in JavaScript for one person.

It’s knowing your data, and how you would organized it into items you would chart.

Draw the chart on paper, what are the x and y axis?, how do you get your data into points along the line.
