Give datapoint and series indexes to "click" chart event.

[ThinkSalat]

I'm trying to set an annotation on the x axis that displays the date where ever the user clicks.

It's a date, so I need the data from my series, something like how other events give you access to the series and the datapoint and series indices.

The arguments we have access to are event, context, and config. I can't seem to figure out how to access the actual data using that information.

I kind of have a similar problem.

Something strange happened, i used to use the dataPointIndex property to render specific data and it worked pretty well but i discovered after seeing that i rendered no data that the config property didn't contain the dataPointIndex property anymore, it only contains config and globals.

I did not update the package.

Is there a condition for config to give dataPointIndex ?

@mikedotJS Which event you used to get dataPointIndex? The click event?

[mikedotJS]

Yes, the click event from a Bar typed chart.

[junedchhipa]

It provides the correct seriesIndex and dataPointIndex when I tried on a column/bar chart. Can you please provide your code?

[mikedotJS]

The code, working pretty well until recently.

  const handleBarClick = ({ clientX, clientY }, chartContext, { dataPointIndex ) => {
    setAreDetailsVisible(areVisible => {
      if (!areVisible) {
        setDetailsStyle({
          ...detailsDefaultStyle,
          left: clientX,
          top: clientY,
        });
        setCurrentDataPointIndex(dataPointIndex);
      }
      return !areVisible;
    });
  };

  const barOptions = {
    chart: {
      events: {
        click: handleBarClick,
      },
    },
    plotOptions: {
      bar: {
        horizontal: true,
      },
    },
    colors,
    dataLabels: {
      enabled: true,
    },
    xaxis: {
      categories: personaeNames,
    },
  };

const barSeries = [
    {
      data: personaeIndexes,
    },
  ];

<Chart
   height="100%"
   options={barOptions}
   series={barSeries}
   type="bar"
   width="100%"
/>

I just tested on a brand new CodeSandbox and it worked as it did formerly for me.

So now the question is : what in my context makes them disappear ?

[ThinkSalat]

const handleBarClick = ({ clientX, clientY }, chartContext, { dataPointIndex ) => {

Whoa. Just tried destructuring the way you did and it worked! Amazing!

Now I'm having another issue. I'm adding annotations using ApexCharts.exec(chartId, 'addXaxisAnnotation', params) in the onClick event.

I also check if there is an existing annotations using context.config.annotations.xaxis

However, the annotations I'm adding are not showing up here.

instead of switching the date and location of the annotation, it's just adding a bunch of new ones, and none of them show up in the context. how can we access the current annotations from the click event?

I have a question, the dataPointIndex is -1 for the first item. Shouldn't this be 0?

[amstrad]

Hi, i´m using vue-apex-chart and i can´t sadly get dataPointIndex when using click event.. it does on dataPointSelection event..but sadly that only works when i click over the bar with data, not good experience for low or zero heigh bars...maybe i´m doing something wrong or should i check something else than click/dataPointIndex Would appreciate any idea

[sleleko]

Hi! How open other detailed chart when I get seriesIndex and dataPointIndex? And how send it's for open new chart with more detailed info? May be any were exist some example ?

Hi! try use example from doc (https://apexcharts.com/docs/options/chart/events/) chart: { events: { click: function(event, chartContext, config) { // The last parameter config contains additional information likeseriesIndexanddataPointIndexfor cartesian charts } } }

In config you can find dataPointIndex . But how work with him? I,m use vue-apexcharts too

hi everyone. i am a newbie to reacjs apex chart. I have this graph. the first grap is for LGAs in that state and the second graph for the wards in a particular lga. i want to add a click event to the first bar chart. that when I click a bar for a particular lga, the second graph will show the graph for all the wards in that lga. how can I achieve this?
