ApexCharts card - A highly customizable graph card

I was using a line and a column - how can I change the width of the bars? I followed vdrainers post for the line width but the bars are too wide particularly on a mobile device…

You could try with:

        apex_config:
          plotOptions:
            bar:
              columnWidth: '70%' # 70% is the default value

Thanks. I did look in the apex docs but they are not that easy to navigate.

No they are not, but it still provides great insights. You’ll learn where to look while using it more :slight_smile:

I got it working and even zooming works! That is what I always found lacking in Home Assistant lovelace graphs. The only thing I don’t know is how to zoom out. I think the ‘toolBar’ option (https://apexcharts.com/javascript-chart-demos/line-charts/zoomable-timeseries/) is not working yet?

toolbar works, it’s here:

apex_config:
  chart:
    toolbar:
      show: true

Ok, really great, going to test now!

          - type: custom:apexcharts-card
            graph_span: 24h
            header:
              show: true
              title: Media Management
            apex_config:
              stroke:
                width: 3
                curve: smooth
              chart:
                toolbar:
                  show: true
                  tools:
                    zoom: true
                    zoomin: true
                    zoomout: true
                    pan: true
                    reset: true
            series:

Doesn’t show any tools… did I miss something?

This works for me:

type: 'custom:apexcharts-card'
apex_config:
  chart:
    height: 450
    zoom:
      type: x
      enabled: true
      autoScaleYaxis: false
    toolbar:
      show: true
      autoSelected: zoom
    xaxis.type: datetime

Really nice card! I’m about to replace some of my mini-graph-card’s but because of a lot of datapoints, it’s a bit slow. Is there an equivalent of points_per_hour (mini-graph-card) on this card? Thanks!

Yes, you can use group_by in each series to reduce the nb of datapoints. It will aggregate the data the same way mini-graph-card does.
Check the doc on github, it explains how it works :slight_smile:

Can you tell me what I did wrong with the chart zoom/pan options above?

You are missing the zoom part:

            apex_config:
              stroke:
                width: 3
                curve: smooth
              chart:
                zoom:
                  enabled: true
                toolbar:
                  show: true
                  tools:
                    zoom: true
                    zoomin: true
                    zoomout: true
                    pan: true
                    reset: true

Thanks again for the data_generator. I just played with it a bit, but am having a bit of trouble getting to the data I’d like to map. The data state attributes of my weather.openweathermap entity):

My card config:

  - type: 'custom:apexcharts-card'
    graph_span: 8d
    span:
      start: hour
    series:
      - entity: weather.openweathermap
        data_generator: |
          return.entity.attributes.datetime.map((time, index) => {
            return [new Date(time), entity.attributes.precipitation[index]];
          });

This however, returns no data (showing loading on the graph). I suppose it has to do with the fact that datetime and precipitation are not attributes of the weather entity, but are contained in the forecast attribute. Haven’t found a way to get past this yet.

On another note: I tried to use a style attribute on the card (make it wider on my picture-elements card) but get an error value.style is extraneous. The config I tried:

  - type: 'custom:apexcharts-card'
    graph_span: 8d
    span:
      start: hour
    series:
      - entity: weather.openweathermap
        data_generator: |
          return.entity.attributes.datetime.map((time, index) => {
            return [new Date(time), entity.attributes.precipitation[index]];
          });
    style:
      left: 50%
      top: 65%
      width: 90%

Thy with this:

          return entity.attributes.forecast.map((entry) => {
            return [new Date(entry.datetime), entry.precipitation];
          });

I’ll fix that, good catch :slight_smile: Would you mind opening an issue on github please?

          return entity.attributes.forecast.map((entry) => {
            return [new Date(entry.datetime), entry.precipitation];
          });

This didn’t work, I’m afraid.

Going on Github now for the issue with style.

With this exact code:

      - type: custom:apexcharts-card
        graph_span: 8d
        span:
          start: hour
        apex_config:
          dataLabels:
            enabled: true
        header:
          show: true
          title: Precipitation Forecast
        series:
          - entity: weather.home
            type: column
            data_generator: |
              return entity.attributes.forecast.map((entry) => {
                return [new Date(entry.datetime), entry.precipitation];
              });

I get the result you expect:

Edit: Also make sure you are running the last version (and that it is not cached by your browser). Check the console. If you don’t see 1.2.0, clear your cache

Ugh! I didn’t see that in the docs. Thanks.

Latest version and cache have been ruled out, however, still not seeing the bars on my graph. I did find the following error in the console, though:

apexcharts-card.js:1 Error: <svg> attribute height: Expected length, "NaN".

I’m guessing that he doesn’t recognize the precipitation value as a number?
