By customizing markers, the scatter plot in Stata will also be customized. The marker window looks something like as followingĪs shown in the above image, there are different options that could be used to customize our markers. In this window, there are different options that could be used to visualize the markers in Scatter plot in Stata. Once selected, the marker properties window will appear. To deal with markers in Scatterplots in Stata, select the marker properties on the twoway graph window, below the Y variable option, as shown below.
These markers show the points where different observations lie. Markers are the points on the scatter plot used to visualize the presence of points on the graph. Marker Properties in the Scatter Plot in Stata By disabling plot 2 and Plot 3, these fitted lines can be removed. These fitted lines were generated using plot 2 and plot 3, as shown below. The new window will appear where you can disable the both linear and quadratic fitted lines to get the original scatter plots in Stata. To remove these fitted lines, click on the accept button in the plot window as shown below Similarly, these fitted lines can also be removed from the scatter plots created earlier in Stata. One can get the different kind of fitted lines, as per the requirement of their data. There are different kinds of fitted lines option in the stata that can be used.

To get a quadratic line, follow the similar path that was used earlier to get a linear fitted line. Instead of a linear fitted line, we can also get a quadratic fitted line or non-linear fitted line in the Scatter plots in the Stata.
Using Quadratic Fitted Line in the Scatter Plot: The fitted line created will look like this, showing a negative relationship between price and mileage. The following window will appear where the fit plots instead of basic plot will be chosen. To create a fitted line in the scatter plots in Stata, select the Fit plots from the below window and click on the accept button on the twoway graph window as shown in the image below.īy clicking on the accept button, the new window will appear where we choose the create option again. If the fitted line is upward sloping, the relationship is positive and if the line is negatively sloped, the relationship is negative. The fitted line can show the direction of the relationship, whether it is positive or negative. However, the best way to find a relationship between variables in scatter plot is by using fitted line in the generated Scatter plot. Using Fitted Line in the Scatter plot in StataĪs, the prediction is given about the negative relationship between mileage and prices. From the image below, it is clear that there exists negative relationship between mileage and price, thus price decreases when mileage increases and vice versa. The price and mpg will be chosen in the respective dependent and independent variable list as shown below.Ĭlicking on the submit button generates the following scatter plot in the Stata. Simply, we want to study how mileage (mpg) would affect the price of the cars. In the twoway graphs, as shown in above image, the scatter plot in Stata can be created by clicking on the create option, where scatter option is chosen.Īs scatter plot is the relationship between two variables, one dependent and one independent, so our dependent or y variable here is Price and independent variable or x variable is the Mpg. However, our aim is to create scatter plot here, so we will choose the first option of Twoway graphs. Looking at the drop-down list in graphics, it is visible that all kinds of graphs can be created, including pie charts and bar graphs. To create scatterplot for the data we used, click on Graphics in the menu bar. Scatter Plot in Stata Related Book: A Visual Guide to Stata Graphics by Michael N. The data we choose has different variables including price of the cars, their mileage, manufacturing country etc. We will continue with the auto data given on the first row to create scatter plots in the Stata. By clicking on the last option, a list of files or data sets is appeared, by which you can use a given data set to practice on Stata.
