![]() If the given points are (3,2) and (2,3), then plot these two points on the X- and Y-axis. ![]() Question 2: Two different points are to be plotted on a graph. (0, 1) (4, 0) (7, 7) (−5, 0) (−4, 4) (0, −5) (8, 0) (6, 0)Īnswer: Since the coordinates lying on x-axis have their y coordinate zero (0), the following points will lie on x-axis: Question 1: Which of the following points lie on the x-axis? The next step is to plot these ordered pairs on the coordinate plane graph.Īs a final step, we will join these points to form a straight line and that will be the representation of the equation y = x + 1. Now, let’s build a table to represent the corresponding values of y for different values of x and create their ordered pairs: x Let us consider a linear equation, y = x + 1. To understand how to represent a linear equation on the graph using the X- and Y-axis, Representing a Linear Equation on X- and Y-Axis Now, the y-coordinate of B(3,4) is 4, so we will go 4 spaces up from this point.Īnd thus we have plotted our point B(3,4) on the graph using the axes. So we will start from the origin and move 3 units to the right on x-axis. Let us learn how to plot a point on the graph by using the X- and Y-axis.įor example: Let’s try to plot the point B(3,4) on the graph. The origin is where the two axes intersect and is written as (0,0). Here, x represents the location of the point with respect to the x-axis and y represents the location of the point with respect to the y-axis. The x-axis is also called the abscissa and the y-axis is called the ordinate.Īny point on the coordinate plane can be located or represented using these two axes in the form of an ordered pair of the form ( x,y). These two axes intersect perpendicularly to form the coordinate plane. The x-axis is a horizontal number line and the y-axis is a vertical number line. The x and y-axis are two important lines of the coordinate plane. Representing a Linear Equation on X- and Y-AxisĪn axis in mathematics is defined as a line that is used to make or mark measurements.Of course, you can also add a data label to this data point and change the color and/or style of the error bars. Repeat the same for the error bar in the other direction to get the following chart: Next, right-click on either the x- or y- error bar and choose “Format Error Bar”.Ĭhange the direction to “Minus” and the percentage to 100. To add error bars in Excel 2013/2016, with the data series selected, click the green plus sign to the right of the chart, select the box next to “Error Bars” and choose the percentage type. Next, we can add percent error bars to this single-point data series. But this time only select the individual x- and y-values to create a series with a single data point. It still starts by adding a second series to the chart. Instead of using a series to create the horizontal and vertical lines on the scatter chart, his method is to use error bars. I’ve used the above method for a long time, but the next method was recently introduced to me by Jon Peltier of. ![]() Plot Coordinates in Excel Using Error Bars We could also use this method for multiple x/y pairs also: See also Calculating the Integral of an Equation in Excel with VBA So if the desired x-value is updated, the horizontal and vertical markers update as well. Of course, since it’s a chart series it automatically updates. Then we can add a data label and change the horizontal and vertical lines to dashed lines for better readability: So if we start with the data from our table of air density and temperature, then add a second series with those pairs of data (using a scatter plot with straight lines and markers), we get the following: The first and second pair of data points comprise the horizontal line from the y-axis to (x-value, y-value) and the second and third points make up the vertical line extending upward from the x-axis. The lines extending from the x- and y-axes to the interpolated point (x-value, y-value) can be created with a new data series containing three pairs of xy data. It would be nice to know where that data point falls on the x- and y-axes, so let’s look at one of the ways to do that: Plot XY Coordinates in Excel by Creating a New Series The intermediate green point on the line was interpolated from the available data. In the scatter chart below, the blue line represents the available data points. ![]() As an example, I’ll use the air temperature and density data that I used to demonstrate linear interpolation. If you have a scatter plot and you want to highlight the position of a particular data point on the x- and y-axes, you can accomplish this in two different ways.
