Description
Hi, I am currently facing issues adjusting the legend of a plot when a new trace with a new y-axis is added to the plot.
Somehow the legend seems to be overlayed on the newly added y-axis title.
This is my current code set-up:
Angular Template:
<plotly-plot #plotlygraph [style]="{position: 'relative', width: '100%', height: '100%'}"
[useResizeHandler]="true"></plotly-plot>
Angular Component:
// Initial Layout
layout = {
title: 'Anomaly Plot',
autosize: true,
xaxis: {
autorange: true,
type: 'date',
title: { text: 'DateTime' },
},
yaxis: {
autorange: true,
type: 'linear',
title: { text: '°C' },
},
};
// Add new trace with a new y-axis
layout[yaxis2] = {
autorange: true,
type: 'linear',
side: 'right',
title: { text: 'mA' },
};
According to this example here the legend seems to have been adjusted automatically without any further configuration.
Is there a configuration am missing? if not, how can I achieve adjusting the label not to overlay the newly added y-axis?

Research direction
Start with the Angular template and component layout shown in the issue, then compare the dynamic y-axis addition with the linked CodePen example. Reproduce the plot with the added yaxis2 and determine the relevant legend or layout configuration; done means the legend no longer overlaps the newly added y-axis title.
