Setting only min or max values for axis and not a range.

Dear all

Many thanks for all your wonderful efforts with Plotly

I just wanted to ask if it might be possible to tweak the range function a little

currently an axis range can be set in the layout like this …

layout = go.Layout(
xaxis=dict(
range=[2, 5]
),

in some cases it would be desirable to only specify a min value. Plotly can then work out the max value automatically.

Or perhaps a user would want to set a max value and have a plotly work out the min value

Either-way it would be nice (for me at least) to only specify one of the range limits and not both. However I can see why this might not be a highly required function and I’m sure there are lots of other things to do first

matplotlib offers this function …

plt.xlim(2,5) #sets a range
plt.gca().set_xlim(xmin=2) # sets only the lower x value and allows computer to work out upper value
plt.gca().set_ylim(ymax=50) # sets only the lower y value and allows computer to work out upper value

Found the solution for setting the x or y axis’s minimum value to zero. Add the following to the layout() object: yaxis = list(rangemode = 'tozero') or xaxis = list(rangemode = 'tozero')

Same request to set axes separately from python backend

Proposal is to allow pass None if value should be automatically determined: range=[2, None]
