![]() The color parameter enables you to modify the color of the points according to some variable. ![]() This parameter will accept so-called “ named colors“, but hexadecimal colors will work too. I’ll show you an example of this in example 2.īy default, the color is a sort of medium blue, but you can change it to a wide variety of colors. If you plot a scatterplot with multiple colors (i.e., multiple categories), there is a set of default colors that will be applied as the default color palette.īy using the color_discrete_sequence parameter, you can override those defaults, and specify the exact colors that you want for your points or categories of points. If you plot a scatterplot with only one color, then by default, the color the points will be a medium blue. The color_discrete_sequence parameter enables you to modify the interior color of the points (or the whole color palette applied to a set of points). The variable that you provide as the argument to this parameter should be numeric (although the string variables are allowed in some special cases).Īlternatively, if you don’t specify a DataFrame, then you can use the Series or list-like object as the argument to the y parameter. The y parameter allows you to specify the variable that will be mapped to the y-axis. The y parameter is very similar to the x parameter. If you specify a DataFrame with the data_frame parameter, the argument to this parameter should be a name of one of the columns of your dataframe.Īlternatively, if you don’t specify a DataFrame, then you can use the Series or list-like object as the argument to the x parameter. The variable that you use as the argument to this parameter should be numeric (although the function will allow string variables in some special cases). The x parameter allows you to specify the variable that will be mapped to the x-axis. If you don’t provide a DataFrame, then you’ll need to change how you use the x and y parameters. (There are other formats that your data could be in, so you need to be careful about the format of your data.) Tidy data is data structured so that every variable is in its own column and every observation has its own row. Your DataFrame should be in so-called “tidy” format. The data_frame parameter allows you to specify the Pandas DataFrame that contains the data that you want to plot. Let’s quickly discuss each of these data_frame (required) So in the spirit of applying the 80/20 rule, I’ll explain what I think are the most important parameters that you should learn first: The truth is, you’ll probably only use a few of these regularly, so it’s a poor use of time to try to explain all of them. The px.scatter() function has roughly 4 dozen parameters that you can use modify your Plotly scatterplots. Let’s look at those parameters, and then we’ll look at some examples afterward. This is the common convention, and we’ll be sticking with it in this tutorial.īeyond a basic scatterplot, there are some variations on the scatterplot that you can also create by using a few parameters. Note that this assumes that you’ve imported Plotly Express as px. In the simple case, you simply call the function as px.scatter, provide the name of the dataframe you want to plot, and them map variables to the x and y axes. The syntax to create a scatterplot with Plotly Express is fairly simple. Here, I’ll walk you through the basic syntax for a Plotly Express scatterplot, and I’ll explain a few additional parameters that will enable you to modify your plots. There are actually several ways to create scatterplots in Python (i.e., the Seaborn scatter and Matplotlib scatter) and there is also more than one way to create a scatterplot with Plotly.īut the easiest way to create scatter plots with Plotly is with the px.scatter function from Plotly Express. Then, individual observations in the data are plotted as points. One numeric variable is mapped to the x-axis, and the other is mapped to the y-axis. However, if you’re new to Plotly or new to data science in Python, everything will probably make more sense if you read the whole tutorial.Ī quick introduction to the Plotly scatter plotĪs you’re probably aware, a scatterplot is a data visualization that plots two numeric variables. If you need something specific, you can click on any of the links above. ![]() It will also show you clear, step-by-step examples of how to create a scatter plot in Plotly express. So the tutorial will explain the syntax of the px.scatter function, including some important parameters. Specifically, it will show you how to create a scatterplot with Plotly express. ![]() This tutorial will show you how to make a Plotly scatter plot.
