Apply axis styling to all subplot axes in a plotly figure

Source: R/plot_axis.R
apply_subplot_axis_styling.Rd

When using plotly subplots (e.g., via split.by in dittoViz), axis styling must be applied to all subplot axes (xaxis, xaxis2, xaxis3, etc.) individually. This helper function detects how many subplots exist and applies the provided axis styling to all of them.

Usage

apply_subplot_axis_styling(fig, xaxis_style, yaxis_style)

Arguments

fig

A plotly figure object.

xaxis_style

A named list of axis styling parameters for x-axes.

yaxis_style

A named list of axis styling parameters for y-axes.

Value

The modified plotly figure with axis styling applied to all subplots.

Details

The styling is queued with plotly::layout(), which merges it into each axis when the figure is built, so the axes' other properties (range, domain, title text, ...) are kept. Only the styling is queued, never a copy of the axis as it stands, so a property written to the figure's layout after this call (such as a range raised by apply_stat_annotations()) is not reverted at build time.

Examples

fig <- plotly::plot_ly(mtcars, x = ~wt, y = ~mpg, type = "scatter", mode = "markers")
xaxis_style <- list(showline = TRUE, linecolor = "black", linewidth = 1)
yaxis_style <- list(showline = TRUE, linecolor = "black", linewidth = 1)
apply_subplot_axis_styling(fig, xaxis_style, yaxis_style)
