Note that multiple color scales can be linked to the same color. The Plotlycolors argument accepts explicitly-constructed color sequences as well, as lists of CSS colors: Warning: If your color sequence has fewer colors than the number of unique values in the column you are mapping to color, the given colors will be mapped for some values and random colors will be mapped for other values : The example above assigned colors to data values on a first-come-first-served basis, but you can directly map colors to data values if this is important to your application with colors. In most cases, discrete/qualitative/categorical data values have no meaningful natural ordering, such as in the continents example used above. Now we will plot the same graph with the discrete color technique. fig = px.scatter(df, x="sepal_width", y="sepal_length", color_discrete_sequence=['red']) This argument is to use a custom color paletter for discrete color factors, but if you are not using any factor for color it will use the first element for all the points in the plot. No interpolation occurs when using color sequences, unlike with continuous color scales, and each color is used as-is. Mapped variables on the x/y-axis are the number of babies and the years they are born in. Not the answer you're looking for? This means that numeric strings must be parsed to be used for continuous color, and conversely, numbers used as category codes must be converted to strings.

Python Plotly can be used to display both the color representation i.e. This document explains the following discrete-color-related concepts: Most Plotly functions accept a color argument which automatically assigns data values to discrete colors if the data is non-numeric. Built-in color scales are stored as a string of CSS colors: A collection of predefined sequential colorscales is provided in the 'RColorBrewer' package. This means that numeric strings must be parsed to be used for continuous color, and conversely, numbers used as category codes must be converted to strings. In some cases, however, there is a meaningful order, and in this case it can be helpful and appealing to use part of a continuous scale as a discrete sequence, as in the following wind rose chart: This works because just like in px.colors.qualitative, all built-in continuous color scales are stored as lists of CSS colors: Dash is an open-source framework for building analytical applications, with no Javascript required, and it is tightly integrated with the Plotly graphing library.

Get started with the official Dash docs and learn how to effortlessly style & deploy apps like this with Dash Enterprise. For discrete colors, we need to calculate the exact values of the tip instead of the value range. Note that this does not change the order in which values appear in the figure or legend, as can be controlled below: If your data set already contains valid CSS colors which you wish to use directly, you can pass the special value "identity" to colors, in which case the legend is hidden by default, and the color does not appear in the hover label: Plotly lets you specify an ordering over categorical variables with categoryorder, which will apply to colors and legends as well as symbols and axes. These strings are case-sensitive. paletteer_c ("ggthemes::Red-Green-Gold Diverging", 30) paletteer_c ("ggthemes::Sunset-Sunrise Diverging", 30) This is the reproducible example: And the code to produce the heatmap in plotly: As you see, the produced plot has a scale that is continuous.
