Color sequence defaults depend on the colors attribute and can be explicitly specified using a vector of colors as argument. The colorscale must be an array containing arrays mapping a normalized value to an rgb, rgba, hex, hsl, hsv, or named color string. The custom string value can be assigned to the name argument, which results in a modified legend name in the following example code. grep is used to search or matches to argument pattern within each element of a character vector: they differ in the format of and amount of detail in the results. Making statements based on opinion; back them up with references or personal experience. This page is about using color to represent categorical data using discrete colors, but Plotly can also represent continuous values with color. the answer I provided that is linked by @r-beginners is generic in this respect. Plotly Express lets you specify an ordering over categorical variables with category_orders, which will apply to colors and legends as well as symbols, axes and facets. By default, Plotly will use the color sequence from the colors attribute, and the default active template is plotly which uses the plotly color sequence. Dash for R is an open-source framework for building analytical applications, with no Javascript required, and it is tightly integrated with the Plotly graphing library.

Plotly R supports a large number of built-in continuous color scales. For example, in the tips dataset, the smoker column contains strings: The size column, however, contains numbers: Converting this column to strings is very straightforward, but note that the ordering in the legend may not be sequential by default, but here it produces sequentially (see below for how to control discrete order): Converting a string column to a numeric one is also quite straightforward: Dash for R is an open-source framework for building analytical applications, with no Javascript required, and it is tightly integrated with the Plotly graphing library. Since build_plotly() (the function plotly() calls internally) always calls brewer.pal() (see line 474 here), it's not possible to fix this without rewriting the build_plotly() function to not call brewer.pal() with fewer than 3 data classes. Just like in ggplot2, you'll have to specify a color in one of the following ways:.
