ApexCharts EVAL function for writing to the log?

[mafieu86]

Hello, I'm having trouble writing to the system logs when a user clicks on an ApexCharts graph.

My initial idea was to control an input field by clicking on a bar in the chart, but that didn't work. So, I tried to simplify it by just writing something to the log, but I've noticed that clicking on the chart doesn't do anything at all.

Here's the code for my chart.

Is there a problem with my EVAL function?

Am I missing something?

type: custom:apexcharts-card
header:
  show: true
  title: "TEST — clic global (events.click via this.hass)"
apex_config:
  chart:
    events:
      click: |
        EVAL: (event, chartContext, opts) => {
          try {
            this.hass.callService('system_log','write',{
              message: 'Apex CLICK (events.click): coucou',
              level: 'warning',
              logger: 'custom.apexclick'
            });
          } catch(e) {
            console.warn('apex click error', e);
          }
        }
graph_span: 2d
all_series_config:
  type: column
  group_by:
    duration: 1d
    func: max
    fill: 'zero'
series:
  - entity: sensor.energie_piscine_jour_hp
    name: HP
  - entity: sensor.energie_piscine_jour_hc
    name: HC

Thank you very much for your help.

If it is just logging then you could also achieve this via tap_action but I guess you are looking for more.
hass is only there in transform and data_generator.... here you could get it via the DOM ...at least, this is what I found a while ago
document.querySelector('home-assistant').hass

thx so much !!!!
Amazing, this is the solution for me !

do note it is really hack-a-like ... maybe @RomRider has an idea on how to improve on this, on the other hand, your use/request is way at the edge what 'nomal' (sorry) people use :)

and btw, I suggest to not post in two locations...
if you want to ask things on the forum, I suggest to use the big (huge) one as this is used by most, single posts often donot get attention. Both have their (dis)advantages but few people use github https://community.home-assistant.io/t/apexcharts-card-a-highly-customizable-graph-card/272877
