Persistent data with Bar-Chart node #13

Open Soiski71 opened 1 year ago

Soiski71 commented 1 year ago

Hi, I'm sorry but I need to come Back on the Bar-Chart Node and how it handles the persistent data. With this simple data flow I'm trying to reset the last combined data from bar-chart (when node red service is restarted). If I connect the persistent data to the final chart flow it shows it in the start correctly (restore works from flow TEST2), but immediately once new data is inserted to bar-chart flow it overrides all restored data with new data (chart data starts from "zero").

If I tried liking the persistent data to bar-chart-data it does not handle it correctly

Can you send a sample code how you have solved that bar-chart-data fully survives a node-red system restart.

Help much appreciated !

I gave you an example in https://github.com/arneman/node-red-contrib-dashboard-bar-chart-data/issues/8

In your example you only store the payload of the message and you inject the stored data after the bar-chart-data node, but it has to be injected before (and then bar-chart-data sends a new message to the chart).

another example without persist node: [ { "id": "35cacbff598f14a1", "type": "bar-chart-data", "z": "faf7d35d62e6719c", "name": "bar-chart-data", "x_interval": "seconds", "x_size": "60", "unit": "", "precision": 2, "is_meter_reading": "False", "agg_by": "sum", "x": 560, "y": 560, "wires": [ [ "f40133052733dd08", "6ab8252d49d27fdb" ] ] }, { "id": "a43fc9b07b7fd6de", "type": "inject", "z": "faf7d35d62e6719c", "name": "", "props": [ { "p": "payload" }, { "p": "topic", "vt": "str" } ], "repeat": "", "crontab": "", "once": false, "onceDelay": "20", "topic": "test", "payload": "1", "payloadType": "num", "x": 310, "y": 560, "wires": [ [ "35cacbff598f14a1" ] ] }, { "id": "6ab8252d49d27fdb", "type": "function", "z": "faf7d35d62e6719c", "name": "store", "func": "flow.set('bar-chart-data-store', msg);\nreturn msg;", "outputs": 1, "noerr": 0, "initialize": "", "finalize": "", "libs": [], "x": 750, "y": 620, "wires": [ [] ] }, { "id": "89b6d0fa150e7fec", "type": "function", "z": "faf7d35d62e6719c", "name": "restore", "func": "msg = flow.get('bar-chart-data-store' || {});\nreturn msg;", "outputs": 1, "noerr": 0, "initialize": "", "finalize": "", "libs": [], "x": 440, "y": 480, "wires": [ [ "35cacbff598f14a1" ] ] }, { "id": "655a4109fe0262a4", "type": "inject", "z": "faf7d35d62e6719c", "name": "after restart", "props": [ { "p": "payload" }, { "p": "topic", "vt": "str" } ], "repeat": "", "crontab": "", "once": true, "onceDelay": 0.1, "topic": "", "payload": "", "payloadType": "date", "x": 230, "y": 480, "wires": [ [ "89b6d0fa150e7fec" ] ] }, { "id": "f40133052733dd08", "type": "ui_chart", "z": "faf7d35d62e6719c", "name": "", "group": "20ad50091d22a9aa", "order": 9, "width": 0, "height": 0, "label": "chart", "chartType": "bar", "legend": "false", "xformat": "HH:mm:ss", "interpolate": "linear", "nodata": "", "dot": false, "ymin": "", "ymax": "", "removeOlder": 1, "removeOlderPoints": "", "removeOlderUnit": "3600", "cutout": 0, "useOneColor": false, "useUTC": false, "colors": [ "#1f77b4", "#aec7e8", "#ff7f0e", "#2ca02c", "#98df8a", "#d62728", "#ff9896", "#9467bd", "#c5b0d5" ], "outputs": 1, "useDifferentColor": false, "className": "", "x": 810, "y": 540, "wires": [ [] ] }, { "id": "20ad50091d22a9aa", "type": "ui_group", "name": "Default", "tab": "15ab88b14795fa9a", "order": 1, "disp": true, "width": 22, "collapse": false, "className": "" }, { "id": "15ab88b14795fa9a", "type": "ui_tab", "name": "X-TEST", "icon": "dashboard", "disabled": false, "hidden": false } ]
