Clone figure.layout so plotly.js doesn't mutate it

[valentijnnieman]

This fixes the bug where Graphs would resize when only supplying one of either width or height in figure.layout, especially visible in a Tab component.

• Can we create a test case for this? You could run through the example that you created and take screenshots on every click. If you rebase, then we should see the test fail before the commit and then fixed after the commit.
• Can we create a new issue about cloning data and include some of the notes from our internal discussion about cloning data arrays?

@chriddyp Created issue #287 and wrote a test.

[chriddyp]

Instead of sleeping, could we try adding an element with an ID inside tab-2-example and then doing a self.wait_for_element_by_css_selector('#tab-2-element')? In principle it should be more stable.

[chriddyp]

Although maybe let's try to start using the official selenium API rather than my wait_for_element_by_css_selector api, which might be buggy. more context here: #288

thanks! 💃

Can you re-base? You would just need to change PlotMethod to Plotly.react

[radekwlsk]

Change introduced in 0.28.1 breaks my candlestick dcc.Graph.

Changed

candlestick and OHLC charts are now plotted using the Plotly.react method instead of the Plotly.newPlot method.

On 0.28.0 it works correctly.

My dcc.Graph has initially empty figure and is in a hidden html.Div, once button of input form is pressed the callbacks generating data, and returning it to output which is figure of a dcc.Graph fires together with callback that sets hidden=False of the html.Div containing the graph.
On 0.28.1 it does not resize correctly to page width set in CSS, the figure only has height=900 set.

Is that what those changes fix?

@radekwlsk - Can you create a small, reproducable example?

[rmarren1]

@radekwlsk This is a known issue: https://community.plot.ly/t/plotly-resize-bug-using-html-details-hidden-div-and-width-100/11201/6

I think that the temporary patch on candlestick we had between 0.22.1 and 0.28.1 fixed this on candlestick, but lead to other bugs.

I think that as a work-around, you can display an empty Div (no children) when you should have hidden=True and then, rather than setting the figure prop of your Graph with a callback, you can set the children prop of your Div with a newly constructed Graph. This way, it will re-size.

Can this be closed? #256

[valentijnnieman]

@rmarren1 Yep.
