Description
Description
There is an issue with the title's automargin feature when a slider or buttons are displayed. In this case, when automargin increases the top margin, it will push down the chart’s tick labels (correctly) but will NOT push down the traces. Then, the trace is in the wrong location on the y-axis and misrepresents the data values.
Screenshots/Video
Steps to reproduce
- Go to the sample codepen from https://plotly.com/javascript/sliders/#add-a-play-button-to-control-a-slider :
https://codepen.io/plotly/pen/NbKmmQ - Add the following to the layout:
margin:{autoexpand:true, t:0}, title:{automargin:true, text:"Title"}, - You can see that the yaxis ticks do not line up with the data/trace
Notes
This seems to be a combination of margin:{autoexpand:true}, title:{automargin:true} and having sliders and/or buttons displayed. You can also set a bigger title font (like font:{size:"36"}) for this to have a greater effect.
