![]() To do so, we can once again open the Chart Builder and choose Grouped Scatter as the chart type. ![]() In this case, we could create a scatterplot of hours studied vs. Suppose we also have a categorical variable in our dataset, such as gender: In this case, it means 66.2% of the variation in exam scores can be explained by the number of hours spent studying. This represents the percentage of variation in the response variable that can be explained by the predictor variable. The R 2 value also appears in the top right hand corner of the plot. Once we click OK, a scatterplot with a line of best fit will appear: We can also produce a scatterplot with a line of best fit by selecting the option called Simple Scatter with Fit Line in the Chart Builder window: Once you click OK, a new scatterplot will appear with the y-axis minimum value set to 0: To change this to 0, click Y-Axis1 (Point1) in the Element Properties box and set the Minimum value to 0: In this example the minimum point on the y-axis is 65. Once you click OK, the following scatterplot will appear:īy default, SPSS chooses a minimum point for the y-axis based on the smallest value in your dataset. Drag the variable hours into the x-axis and score into the y-axis: Then drag the first option that says Simple Scatter into the editing window. In the window that pops up, click Scatter/Dot in the Choose from: list. ![]() We can create a basic scatterplot in SPSS by clicking on the Graphs tab, then Chart Builder: We can create a scatterplot to visualize the relationship between hours studied and exam score received. Suppose we have the following dataset that displays the hours studied and exam score received for 15 students: This tutorial explains how to create and interpret scatterplots in SPSS. It helps us visualize both the direction (positive or negative) and the strength (weak, moderate, strong) of the relationship between the two variables. If you can imagine a weather forecast with arrows, thats the effect I'm looking for.A scatterplot is a type of plot that we can use to display the relationship between two variables. Willing to take a long path to enlightenment and learn but equally if anybody has any ideas or solved solutions it would be great. But I am afraid it is way beyond my intellect and talent. I came across the piedatamarkers.xls which uses a macro to replace the dots with pie charts (that are themselves configurable), credit to Andy Pope with additionally his gauge chart on shows a good way of rotating a variable length (representing wind speed) line according to angle (wind direction if it was an arrow) so it seems it is in the art of the possible. Ideally I would also want to show the speed and direction as a data label next to them. That was failry easy but now I'm looking for a way (a macro maybe) to replace the plotted points with an arrow that inidcates direction and speed. I have already configured a chart that plots the lat/long (converted the the lat/long to decimals etc) and plotted their positions on an xy chart with the image in the background. I want to plot the wind and speed values as arrows (small arrow, low speed etc) on an x y scatter chart overlayed on top of a map image. I have a large list of wind speed and direction values for a fixed range of latitudes and longitudes taken over 8 weeks.
