renderGauge: Render the Gauge Chart Plotted by ECharts into Shiny...

In ECharts2Shiny: Embedding Interactive Charts Generated with ECharts Library into Shiny Applications

Description

renderGauge() function helps render the gauge chart into Shiny application.

Usage

renderGauge(div_id, theme = "default", gauge_name, rate,
            show.tools = TRUE,
            animation = TRUE,
            running_in_shiny = TRUE)

Arguments

div_id	The division id users specified for this chart. The division will be specified in ui.R.
theme	Which ECharts theme to use. Valid values include "default", "roma", "infographic", "macarons", "vintage", "shine", "caravan", "dark-digerati", "jazz", and "london".
gauge_name	The title to show on the gauge. It can not be ignored.
rate	As the gauge helps show some kind of rate, users need to give this rate value. It must be numerical or integer values.
show.tools	If display the tool bar. The default value is TRUE.
animation	Whether display the chart with animation. The default value is TRUE.
running_in_shiny	If we're actually running this in a Shiny library, or we're simply doing testing. Default valus is "TRUE". If "FALSE", the function will print what it's supposed to evaluate.

Note

Users need to state the division for the chart first, with tags$div() function of Shiny packages. Please note that the division id must keep unique (duplicated division id will cause error).

  }

  # UI layout -------------------------------------------------
  ui <- fluidPage(
    # We MUST load the ECharts javascript library in advance
