Chart titles in Plot or Plotlyjs?

[gganapat]

Hi:

Notebook 2.0 is a huge improvement over earlier versions which was quite buggy. It's becoming more feasible to do relatively complex computations. The documentation progress is commendable. I have a question on plotting. I could not get layout to work with Plotly. I was assuming something like this would work.

trace1 = <|
	"x" -> dat, 
	"y" -> power, 
	"mode" -> "markers",
    "layout" -> <|"xaxis" -><|"title" -> "Date"|>, "yaxis" -><|"title" -> "Power"|>|>;
|>;

Plotly[trace1]

Plot without layout works but I tried different layout options and none work. Trying to add Plot Title, change width, height also failed. Any tips?

Thanks!

We are very glad to hear that! 🚀

Regarding Plotly it was actually a bug.., that we did not pass Layout correctly. A new version is uploaded, you only need to open Settings and click Check Updates it will force frontend to fetch new version on the next startup.

The correct example then will look like

trace1 = <|
	"x" -> Range[100], 
	"y" -> Sinc @ Range[100] // N, 
	"mode" -> "markers"
|>;

layout = <|"xaxis" -><|"title" -> "Date"|>, "yaxis" -><|"title" -> "Power"|>|>;

Plotly[trace1, layout]

probably we need to use different margin parameter for default, but you can specify it in layout association

For more information in API, please check

• Plotly
• PlotlyAddTraces
• PlotlyDeleteTraces
• PlotlyExtendTraces
• ... etc in the same section

Regarding native Plot function

Yes, it still does not support PlotTitle, but PlotLegends kinda work in most cases.
