1. Axis Tick Labels

I want to display overlapping boxplots using Sigmaplot 12. When I choose the scale for the x-axis as linear then the boxes do indeed overlap but are much too thin.

See figure below. Of course they should be much wider.When I choose the scale of the x-axis to be 'category', then the boxes have the right width, but are arranged along each single x-value.I want the position as in figure 1 and the width as in figure 2.

I tried to resize the box in figure 1 but when I choose 100% in 'bar width' than it still looks like Figure 1.many thanks! Okay, I found the answer myself.

Axis Tick Labels

In Sigmaplot, there is often the need to prepare 'style'-columns, for example if you want to color your barcharts, you need a column that holds the specific color names.For my boxplot example I needed a column that has the values for 'width'. These had to be quite large (2000) in order to have an effect. I have no idea. First I thought it would be because of the latitude values and that the program interprets the point as '1.000's, but when I changed to values without decimals, it didn´t get better.Well, here is the result in color.Have fun!

How to: space two or more separate bar plots on the same graphThere are times where you need to create bar charts of extremely disparatedata that requires two separate plots. Spacing these bars correctly can betricky. The best means is to plot each bar chart at a specific x-offset value,so that when the bar widths are adjusted, the bars will be correctly spaced.Here is an example on how to create a graph as shown:1.

If you need to plot a grouped bar chart with two axes, youwill need to create two bar plots on the same graph. However, if you do that,typically the bars will simply plot on top of each other:2. To avoid this, you need to use different, numeric X valuesfor each bar chart. In this example, you could enter:A OffsetB Offset0.1.as your different X offset numbers. If you pick these as your x data columnsfor the two different bar charts, you get:3. This isn’t exactly what you want yet. Now you needto go and reduce the bar widths appropriately.

Change the widths of the barsfor each plot to 40%, then click Apply.4. Now change the Fills to the color you want for each plotand click Apply.5. You’re not done yet! You need to label the X axis properly.Double click the axis, and change the Scale so that the Nearest Tick optionis unchecked, then click Apply.6. Go to the Ticks panel, and set the tick increment to Manual,at intervals of Every 1.7. Finally, go to the Tick Labels panel, and select the originalX Category column as the tick labels.8. Click OK to finish, then double click the legends to editthem as desired.
