Question

I have a stacked bar chart, whose x axis labels would be date, the labels are overlapping how do I arrange them in such a way that it does not overlap on the next label of x axis.

I did not get how to arrange them changing the angle of the label, can anyone help me out solving the problem.

const myDataset = [
  [
      { x: "20/10/2020", y: 18653 },

];

class App extends React.Component {
  // This is an example of a function you might use to transform your data to make 100% data
  transformData(dataset) {
    const totals = dataset[0].map((data, i) => {
      return dataset.reduce((memo, curr) => {
        return memo + curr[i].y;
      }, 0);
    });
    return dataset.map((data) => {
      return data.map((datum, i) => {
        return { x: datum.x, y: (datum.y / totals[i]) * 100 };
      });
    });
  }

  render() {
    const dataset = this.transformData(myDataset);
    return (
      <div>
        <VictoryChart height={400} width={400}
          domain={{ x: [0,5], y: [0, 100000] }}
          domainPadding={{ x: 30, y: 20 }}

             data={data} key={i} labelComponent={<VictoryLabel y={250} verticalAnchor={"start"}/>}/>;
              })}
            </VictoryStack>
            <VictoryAxis dependentAxis />
            <VictoryAxis 
            padding={{ left: 80, right: 60 }}
            axisLabelComponent={<VictoryLabel angle={20}/>}
            tickFormat={["20/oct/20","21/oct/20", "23/oct/20","24/oct/20","25/10/20"]}/>
        </VictoryChart>
      </div>
    );
  }
}

ReactDOM.render(<App/>, mountNode);

The above code can be copy pasted in below link and can edit https://formidable.com/open-source/victory/gallery/100-column-chart/

Is there any way that I could arrange them like below.

Answer 1

I've gotten it to work by passing a VictoryLabel with a -45 degree angle to the tickLabelComponent prop on your independent axis:

<VictoryAxis tickLabelComponent={<VictoryLabel angle={-45} y={350} />} />

So instead of passing the VictoryLabel to the axisLabelComponent prop on the VictoryAxis, pass it to the tickLabelComponent prop.

You might also need to add some padding to your VictoryChart component if the labels are cut off:

padding={{top: 100, bottom: 90, left: 70, right: 80}}

Answer 2

This is the solution i used. I had to display time on the x-axis.

In your case, you can take off the tick formatting from the VictoryAxis and let VictoryChart do the date formatting by adding property scale={{x: 'time'}} to VictoryChart

And then add fixLabelOverlap to VictoryAxis which fixes the overlap issue.
