flow example for bar chart to track number of starts daily please?

Open houser42 opened this issue 4 months ago • 3 comments

Is there an example somewhere for a bar chart to track number of starts daily? We have a machine that we would like to have a bar chart that shows how many starts it does daily, so one new bar for each day that shows number of starts as bar and a number count. We are so far unable to accumulate the payload count in a bar chart. We are now sending a number:1 to the bar chart every time it starts, but the chart does not add, but creates a new bar for each payload.

Is there any flow example or good starting point out there please? Many thanks!

You might be better to ask for help on the node red forum. It will be seen by a wider audience there.

Thanks, I will, but figured the expertise on the flow fuse V2 chart is here. I have the basic payloads and such working. Just wondering if it is possible to configure the chart as a one bar per accumulated day, and if so how. Ah well. Thanks again.

Rather than type "Bar", you can use type "Histogram", and it will accumulate based on the category/x-value sent: https://dashboard.flowfuse.com/nodes/widgets/ui-chart#histograms
