The easiest way to visualise serial port in to line chart
Do we have any example showing us getting data from serial and visualising it on the line chart?
So I started exploring stm32cubemonitor. First I tried this configuration by reading directly variable register but it didn't work for me, i was getting 0 values and line charts don't make sense in this case.
I build my application on zephyrOS. So the issue may be because of that. But anyway, I dont have time to figure it out now. So I decided to move getting data from serial comport and show it on the line chart but I couldn't find any examples
here is my basic flow, but I know it is not easy like this above, so First I checked the data structures chart node can accept and visualise it. And it is:
The following example shows an input msg for a chart node for the variable "var1" :
{
"topic":"data",
"payload":
{
"groupname": "groupname1",
"variablename": "var1",
"variabledata": [
{
"x": "0",
"y": "1231"
},
{
"x": "1",
"y": "12"
},
{
"x": "2",
"y": "3615"
}
]
}
}So I am printing out exactly in this structure but I cant still see anything on the chart. So can anyone shed some light on how to fix it? An example would be nice.
Cheers!
