I can find how to set the width/height of the figure by changing the ‘layout’ attribute. How can I set height/width of individual subplots? Is this functionality available?

Hi there,
For individual heights/widths of subplots, check out this tutorial: [https://plot.ly/python/subplots/#custom-sized-subplot](https://plot.ly/python/subplots/#custom-sized-subplot)
You need to fiddle with the xaxis/yaxis domains to get a proportion that you want.
Hope this helps!

Thanks Adam,
I am able to change the xaxis/yaxis domains as per the tutorial. But it appears to be a relative size (since it normalizes to 1). What I want to be able to do is to set a size in pixels for width and height for individual subplots. this way I can ensure, the plots don’t become tiny when I am plotting 10 rows x 10 cols. I am ok with scrolling the page in my browser to see the plots. Is there a way to do that?

Example of what I am referring to…

@Adam, just checking back to see if you had any insights. If there is no way around it, it would be helpful to know 🙂

If you want to set width/height of subplots in pixels you first
set the `layout.height`, `layout.width`, `layout.margin.top`, `layout.margin.bottom`,`layout.margin.left`, `layout.margin.right`, in pixels.
Then the plotting rectangle has the width =layout.width - layout.margin.left - layout.margin.right
and the height= layout.height - layout.margin.top - layout.margin.bottom.
In such a rectangle you set the width and height of each subplot, in pixels.
Then you define a scaling map from the rectangle
[0, layout.width - layout.margin.left - layout.margin.right]x[0, layout.height - layout.margin.top - layout.margin.bottom] to the rectangle [0,1]x [0,1].
This mapping let you find out the domain for the xaxis, yaxis associated to your subplots.

Thanks @empet. This does the trick!

Hi,
Would anyone mind posting some small code example of how to fix a constant height for each subplot? I’m basically aiming for something as @siddharthm in [Setting height/width of subplot](https://community.plotly.com/t/setting-height-width-of-subplot/1861/3?u=jlbgit) , trying to create new (sub-)plots in [plot.ly](http://plot.ly) Dash on button click. I’ve been experimenting with `layout = go.Layout(...`, `figure.layout.update(...` and `figure['layout'][...` but I cannot get it to work properly.
Any help would be much appreciated!
Thanks

@ [siddharthm](https://community.plotly.com/u/siddharthm) can you post a snippet of your code?
got lost with all the params here and where to put them
I want exactly what you did - only 2 columns instead of three

Hi Siddharth,
could it be possible for you to share this portion of your code.
thank you very much in advance for your help
