But I am sure you get such data once in a while. I seldom deal with data that has this kind of outliers.

I have put all these 4 chart examples in a workbook so you can see the underlying technique. Let the bars reach sky: You can of course, set axis max to an arbitrary value, just so that all the small values are clearly displayed and let the higher values literally cut thru plot area. Read broken y-axis to know how to do this.Ĥ. I have used 2 charts and aligned them neatly. Split the axis in to two: This is the most trickiest technique. Use log scale for vertical axis (axis option > check logarithmic scale)ģ. Now, how do you go about making a chart?Ģ. That is, you have data like the numbers shown to right, with a surprising bump during Christmas time. How do we effectively plot all of them in a chart? We have a lot of small numbers and a few very large numbers. Once you have the desired length, you can move it to be positioned at X=1 and change the shape outline to black.Īnd with all those changes, you should be left with a lovely forest plot.Here is an interesting charting problem we come across once in a while. There is no easy way to do this on Excel, so the best method I’ve found is to just manually add a vertical line yourself by going to Insert> Shapes, and then select the straight line option.Ī tip here is when your clicking and dragging to add the line, keep your finger on the shift key to ensure the line will be straight. Lastly, it is common for forest plots that present odds ratios to add a vertical solid line that passes through X=1. In the Format Axis sidebar, I will change the Major Units to be 1 and select to show the Major Tick Marks on the Outside. I will also adjust the X axis by right-clicking on it and selecting Format Axis. To do this, select the X axis and go to Format> Shape Outline and select black. Next, I will add an outline to my X axis so this becomes visible. Simply select a major gridline to select them all and press delete on your keyboard. Remove major gridlinesĪs well as removing the Y axis border, I also recommend removing the major gridlines. To do this, click to select the Y axis and then go to Format> Shape Outline and then select No Outline. Remove Y axis borderĪnother thing I suggest is remove the Y axis border. Also, change the border colour to black too. In the right sidebar, select Fill and Line and go to Marker. To do this, right-click on a point on the graph and select Format Data Series. The first is to change the colour of the scatter points to black, as traditionally forest plot points are solid black circles. There are a few more things we can do before we finish. Format the forest plot Change the scatter points to black Repeat these calculations for all the studies in your sheet.Ħ.

Graph upper 95% CI – Subtract the cell containing the effect size (odds ratio) from the actual upper 95% confidence interval.

Graph lower 95% CI – Subtract the cell containing the actual lower 95% confidence interval from the effect size (odds ratio).

To do this, I will create two new columns in my sheet. In this case, the error bars will represent the 95% confidence intervals.īefore we can do this, we need to calculate the difference between the effect size, so the odds ratio for my example, and the lower and upper 95% confidence interval values. Next, let’s add the error bars to the scatter points. Add error bars (whiskers) to the scatter points To delete this, simply click on the right axis and press delete on your keyboard. Instead, click on any bar to select them all, and then go to Format and change the Shape Fill to No Fill.Īnother thing I suggest you do is to remove the axis on the right, which corresponds to the Positions, as we don’t need to see this. Since we still want to see the study names for our labels to the left of the axis, we cannot simply click on the bars and delete them. Next, we can remove the clustered bar graph, as we don’t need to see this.
