mjs_add_css_rule: Add a CSS rule to the rendered htmlwidget

In hrbrmstr/metricsgraphics: Create Interactive Charts with the JavaScript 'MetricsGraphics' Library

Description

This function will add a CSS rule to a widget-created DOM stylesheet. rule should be a valid CSS rule as you would enter in a <style>...</style> block. No checking is done to ensure validity.

Usage

mjs_add_css_rule(mjs, rule, warn = TRUE)

Arguments

mjs	metricsgraphics plot object
rule	character vector of CSS rule(s) to add to the widget DOM
warn	show warnings for global CSS rules? (default: TRUE)

Details

Use {{ID}} (followed by a space) to target the CSS rule just to the widget vs the whole DOM.

Vectorized over rule

Value

metricsgraphics plot object

Note

This is for expert use only. You need to know quite a bit about the visualization and target DOM to effectively use this function. CSS rules without the {{ID}} are applied to the entire DOM.

Examples

set.seed(1492)
stocks <- data.frame(
  time = as.Date('2009-01-01') + (365 * 0:9),
  X = rnorm(10, 0, 1),
  Y = rnorm(10, 0, 2),
  Z = rnorm(10, 0, 4))

stocks %>%
  mjs_plot(x=time, y=X) %>%
  mjs_line() %>%
  mjs_axis_x(xax_format="date") %>%
  mjs_add_css_rule("{{ID}} .blk { fill:black }") %>%
  mjs_annotate_region("2013-01-01", "2016-01-01", "Crazy times", "blk")
