how to plot a graph in excel using 2 points

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: 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.
