Beschreibung
I am trying to update a whole bar chart using Plotly React.
First I have a bar chart with bars on vertical, then after I click wherever on the chart I would like to rotate the chart 90 degrees and have the bars on horizontal with different data. So X axis becames Y and vice-versa.
I have tried using the revision prop of the <Plot /> component and the layout.dataverision property but it doesn't work.
When I click on the chart, it just empties.
I have
const onUpdate = (event) => {
console.log('update', event);
};
which logs the appropriate data and layout in console before and after the click.
Basically the data updates but the layout does not and the issue comes from the x and y axis trying to display the same type data and not assessing what is the new data.
// here xaxis thinks it has to display strings
// and yaxis thinks it has to display numbers
// which is correct only for the first set of data
xaxis: {autorange: true, range: Array(2), type: "category"},
yaxis: {autorange: true, range: Array(2), type: "linear"}
// the second set of data reverses the x and y axes, so the new properties should be:
xaxis: {autorange: true, range: Array(2), type: "linear"},
yaxis: {autorange: true, range: Array(2), type: "category"}
How can I make Plotly asses the new data and update the layout accordingly ?
Thank you.

Rechercherichtung
Beginne mit der Reproduktion in src/BarChart.js aus dem verlinkten CodeSandbox und untersuche, wie die Plot-Komponente vor und nach dem Klick data, layout, revision und layout.datarevision erhält. Reproduziere den Achsentausch und vergleiche das gerenderte Diagramm mit den protokollierten Props; abgeschlossen ist die Untersuchung, wenn das Ersetzen von data beide Achsentypen aktualisiert und das Diagramm nicht mehr leer wird.
