lc_colourSlider: Add a colour slider

Description

Colour slider provides an easy way to change any continuous colour scale interactively. If your chart uses a continuous colour scale, you can just link a colour slider and it will be automatically synchronized with your chart's colour scale.

Usage

lc_colourSlider(data = list(), place = NULL, ..., chartId = NULL, with = NULL)

Arguments

data

Name-value pairs of properties passed through the dat function. These properties will be re-evaluated on each updateCharts call.

place

An ID of the container, where to place new chart. It will be ignored if the chart already exists. If not defined, the chart will be appended to the web page's body.

...

Name-value pairs of properties that will be evaluated only once and then will remain constant. These properties can still be changed later using the setProperties function.

chartId

An ID for the chart. All charts must have unique IDs. If a chart with the same ID already exists, it will be replaced. If ID is not defined, it will be the same as the value of the place argument. And if both are not defined, the ID will be set to ChartN, where N - 1 is the number of existing charts.

with

A dataset or a list from which other properties should be taken. If the dataset doesn't have a column with the requested name, the variable will be searched for outside of the dataset. Must be a data.frame or a list.

Available properties

You can read more about different properties here.

• chart - ID of the chart to which the colour slider should be linked.

• layer - id of the layer to which the colour slider should be linked. If the chart has only one layer, this property is optional.

Global chart settings

• width - width of the chart in pixels.

• heigth - height of the chart in pixels.

• paddings - padding sizes in pixels. Must be a list with all the following fields: "top", "bottom", "left", "right".

• title - a title of the chart.

• titleX, titleY - coordinates of the chart title.

• titleSize - font-size of the chart title.

Examples

if (FALSE) data("iris")
lc_scatter(dat(x = Sepal.Length, 
               y = Petal.Length,
               colourValue = Petal.Width,
               symbolValue = Species),
           with = iris,
           title = "Iris dataset",
           axisTitleY = "Petal Length",
           axisTitleX = "Sepal Length",
           colourLegendTitle = "Petal Width",
           symbolLegendTitle = "Species",
           showLegend = FALSE,
           chartId = "scatter")
